INTRODUCTION

This document represents a working draft of the strategic plan to restore anadromous fish

species to Rhode Island coastal streams. The project was initiated thanks to a grant provided to

the Department of Environmental Management, Division of Fish and Wildlife (DFW), by Luther

Blount.

The dams of the Industrial Revolution were placed in rivers for an inexpensive and reliable

source of power. Little thought was given to the effects on native fish populations. Fish passage

efforts at the time met with little success. The end result was the extirpation of local populations

of American shad, alewives, blueback herring, Atlantic salmon, and other species. As the

Industrial Revolution waned, so has the need for the dams, yet they remain.

The concept of environmental responsibility is raised for readers of this report to consider.

The dams of the Industrial Revolution in Rhode Island are the most numerous and problematic

impediments to anadromous restoration. Additionally the dams have completely altered the

characteristics of many streams, raising water temperatures, concentrating sediment and

pollutants, buffering the normal and necessary water level fluctuations, and altering the species

composition of flora and fauna. Most of the dams spill water from the top (where the water

temperatures are the warmest). This may result in the equivalent of a series of warmwater ponds

end to end rather a natural stream channel. As many of the dams have already provided their

benefits to Rhode Island and outlived their useful live (as well as pose a hazard), it is suggested

that dam removal be given due consideration as a fish passage alternative. Complete removal of a

dam may benefit a host of fish and wildlife species in any system rather than simply providing fish

passage for certain freshwater and anadromous species. More typical stream corridor vegetation

(both wetland and upland) can become reestablished, ultimately lowering water temperatures

through shading (with corresponding increases in dissolved oxygen), improving water quality

through attenuation of contaminants, and reducing erosion and sedimentation. Where feasible,

dam removal should be considered first.

A great deal of work toward the restoration of anadromous species in Rhode Island

waters where extirpated, has been conducted with varying degrees of success. Little fish passage

work has been done in recent years due to funding limitations. The bulk of RI Division of Fish and

Wildlife, (DFW) effort has focused on transplanting river herring broodstock into areas where fish

passage is already established, and the stocking of hatchery-reared Atlantic salmon fry, parr, and

smolts into the Pawcatuck watershed. Monitoring of returning adults and out-migrating juveniles,

is also conducted annually. Research initiatives on improving upstream and downstream fish

passage from other states and at the federal level, (particularly at the USGS Conte Lab) may hold

some promise for improving anadromous populations.
Rhode Island Anadromous Restoration Plan

Rhode Island has direct control of anadromous species spawning areas and freshwater life

stage juvenile habitats within its borders, but the marine life stages of Atlantic salmon, American

shad, alewives, and blueback herring that are migratory and travel outside of Rhode Island

territorial waters fall under multiple jurisdictions. Rhode Island can protect and enhance

freshwater habitats through fish passage improvements, land acquisition, regulation, and increased

public awareness. Marine life stages protection and enhancement will require interstate

cooperation through the Atlantic States Marine Fisheries Commission (ASMFC), intercontinental

cooperation through the North Atlantic Salmon Conservation Organization (NASCO), and

federal oversight by the United States Fish and Wildlife Service (FWS) and National Marine

Fisheries Service (NMFS).

This report identifies Rhode Island watersheds with the potential to restore, establish, or

enhance anadromous fish populations through upstream passage for migrating adults and

downstream passage for juveniles. In both cases the primary goals are to minimize passage

induced mortality allowing expansion into unutilized and underutilized habitats with the most

cost-effective passage method available. Reintroduction of spawning broodstock is another

critical component of the restoration efforts.

Partnerships between the RI Department of Environmental Management (DEM), US

Army Corps Of Engineers (USACE), NMFS, USFWS, Natural Resources Conservation Service

(NRCS), local interest groups, and an informed constituency will be necessary to fund and

implement the various fish passage methods recommended in this plan.

METHODS

Site inspections were conducted throughout Rhode Island to all streams and rivers

discharging to Rhode Island Territorial Waters. Sections outside of the state boundary are not

included as part of this plan. Site inspections were made on foot, from a canoe, or by boat. The

Blackstone River Watershed was not included as part of this plan. Observations were made for

the various types of spawning and juvenile habitat for the target anadromous species listed in

Table 1. The following were noted during each site inspection:

• Measurements of the width of the stream were taken where appropriate to aid in

habitat area size calculations.

• Obstructions to fish passage were located, measured for height and width (if

appropriate), judged for the type of fish passage methods that might be effective,

and their proximity to anadromous habitat noted.

• Characteristics to aid in judgement of anadromous suitability were noted during

site inspections such as:

• water levels
Rhode Island Anadromous Restoration Plan

• water characteristics

• surrounding land use

• the presence or absence of anadromous species (when and where

appropriate)

• other fish and wildlife species observed

• substrate types

• submerged aquatic vegetation types

• surrounding upland vegetation types

• surrounding wetland vegetation types

• surrounding land use types

• point sources of pollution or runoff

• anything else of significance

This data was stored in spreadsheet database format on a watershed by watershed and stream by

stream basis.

Data from a number of sources was considered in preparation of this report:

• RIDEM Dam Safety Section Database

• Anadromous fisheries surveys (electrofishing, beach seineing, passive capture of

both adult and juvenile migrants, electronic and visual observations and counts of

migrating fish).

• DFW Unpublished stream and pond survey data (for indicator species of habitat

suitability.

• DFW Federal Aid Performance Reports.

• RIDEM DFW Freshwater Fisheries Comprehensive Survey.

• The State of the State's Waters (Section 305(b) 

• USFWS Fish Passage and Diversion Structures Course.

• USGS Topographic map set for Rhode Island.

• Aerial photo-interpretation of photos from RI photo sets.

• RIGIS/RIDEM shapefiles used with ArcView mapping software.

• MapTech Terrain Navigator topographic map software (RI, CT, MA).

• Planimeter and curvimeter. 

For the purposes of this report, dissolved oxygen levels are a parameter used as an indicator of

anadromous suitability.

To simplify the use of this plan, only watersheds judged to have some level of anadromous

suitability for one or more of the target anadromous species are included. Recommendations for

fish passage will range from individual dams all the way to more substantial multiple-fishway

projects necessary to access large areas of habitat. Areas compromised by diminished water

quality will be noted to aid in the restoration decision making process.

The state is broken down into individual watersheds as shown in the Map Legend and

Table 1. Species Suitability Matrix. If any portion of an identified watershed can potentially

support a self-sustaining population of a particular anadromous species, it is indicated by a black

circle. If this is limited for a particular reason or there is anything else worthy of note, it its

indicated by a white circle and comments are included.

One measure of anadromous suitability, for the purposes of this plan, is found in Table 2,

Freshwater Fish Indicator Species For Anadromous Habitat Suitability. It is assumed that if a

particular freshwater body can support the freshwater species in the list, the system has habitat

characteristics suitable for the anadromous target species.

Maps A through O show all watersheds judged to have some level of anadromous

restoration potential. Maps B, C, D, E, H, K, N, and O all have more than one watershed included

on each map because the watersheds are in close proximity to each other. Obstructions to fish

passage are indicated either by a red or green circle. A red circle indicates that the obstruction is

impassible to one or more of the target anadromous species and either requires removal or a fish

passage device to allow access to spawning habitat for the respective species. A green circle

indicates that the obstruction either has a fish passage device or some other characteristic which

allows upstream fish passage. The obstructions are numbered simply for identification purposes.

The upstream limits of suitability as judged by this plan are indicated by the circle with a crosshair.

On maps that include more than one watershed, obstruction numbers commence with “1” for each

respective watershed.

Obstruction Tables 3 through 17 detail the characteristics of the watersheds identified with

anadromous restoration potential. Each obstruction number corresponds with the obstruction

numbers on the maps for the respective watersheds. 

• The column in the tables entitled, “Passage Sequence to Reach Obstruction” identifies the

route the fish will follow while ascending the stream to reach the respective obstruction.

• “Existing Anadromous Population” lists the target anadromous species known to be

established immediately downstream of the obstruction.

• “Species Suitability Immediately Above Obstruction” indicates passage will allow access

to suitable anadromous habitat for the respective species somewhere in that segment or in

an accessible tributary.

• “The Habitat Size Above Obstruction (Acres)” indicates the combined total habitat size,

made accessible by passage beyond the obstruction, for one or more of the target

anadromous species.
Rhode Island Anadromous Restoration Plan

10

• The “Obstruction Height (Feet)” is the vertical height the fish passage device must be

designed for.

• The “Drainage Area - Miles2 ” when known, is included to aid in the design of a fishway.

• The “Recommended Passage Method” if dam removal is not an option, is the suggested

fish passage device based upon the target species, obstruction characteristics, water flow

and watershed size.

• The “Restoration Factor (Acres / Foot)” is simply the acreage of anadromous habitat

divided by the height in vertical feet of the obstruction. This number helps to determine

which restored areas should produce the highest anadromous population size, with the

least financial expenditure. Given as a factor, the number can be used with the most up-todate anadromous population estimate methods and most up to date cost-per-vertical-foot

fishway construction cost estimates.

• “River or Stream” is the name of the mainstem river, stream, brook, or pond in some

cases, where the respective obstruction is located.

• “City or Town” is where the obstruction is located.

• “Dam / Obstruction Name” is the identified dam name from the RIDEM Dam Safety

Section, the name listed in the appropriate USGS topographic map, or identified local

name.

• “State ID No.” is the identified dam’s assigned number from the RIDEM Dam Safety

Section.

• The latitude and longitude for the respective obstructions was determined with MapTech

Terrain Navigator mapping software.

• The “Dam / Obstruction Type” is as described by the RIDEM Dam Safety Section

combined with site inspection observations.

Table 18, Recommended Fish Passage Sites, lists suggested fish passage sites for a number of

watersheds around the state. The projects range from simple projects like the Indian Lake Dam in

the Point Judith Watershed to multiple fishway projects in the Pawtuxet River Watershed.

I. Plan Objective

“To provide a tool that will help identify where anadromous fisheries restoration activities

should be conducted in Rhode Island coastal streams.”

II. Expected Results or Benefits

A strategic plan will assist in the decision-making process regarding the scheduling of

anadromous fisheries restoration in Rhode Island. It will provide an organized framework to

identify and prioritize future work. It will evaluate feasibility of restoration to allow intelligent

allocation of available funds. It will identify short-term and long-term goals that can serve as a

reference to pursue state appropriations, local endowments, and grant opportunities that can be

combined with US Fish and Wildlife Service, (FWS) and National Oceanographic and

Atmospheric Administration, (NOAA) federal grants.

Anadromous restoration will enhance habitat values for a variety of species in both the

marine and freshwater environments. Anadromous species provide both recreational and

commercial fishing opportunities. If dam removal is used as a fish passage method, a more natural

stream corridor may result with some semblance of pre-dam conditions. Aesthetic and educational

opportunities also result from the anadromous restoration effort. People may observe fish

passage, recovery, and monitoring at the respective fishways, observe sampling techniques, and

assist with a variety of volunteer efforts as they become available.

Appendix A. Recommended Watershed Enhancements.

Obstruction locations and characteristics discussed in sections A. through O. In Appendix A. can

be seen in the corresponding watershed map and respective watershed obstruction table. 

A. Pawcatuck River Watershed

The Pawcatuck River Watershed (PRW), one of the three largest in Rhode Island, is located in

the southwestern portion of Rhode Island and southeastern Connecticut. The watershed is

approximately 308 square miles (80% within Rhode Island). Rhode Island portions include the

towns of Westerly, Charlestown, South Kingstown, Richmond, Hopkinton, Exeter and West

Greenwich. Connecticut portions include the towns of Stonington, North Stonington, Voluntown

and Sterling. The basin is approximately 25 miles long north to south, and 24 miles wide east to

west. The mainstem originates at Wordens Pond in South Kingstown, has a course of 31 miles,

and ultimately discharges to Little Narragansett Bay in Westerly. The lower five miles of the river

are tidal.

Aquatic habitats range from warmwater impoundments and flowing water to freestone streams in

the Wood River and Usquepaug River watersheds. Warmwater areas are predominated by

submerged aquatic vegetation, and have habitat suitable for American shad, alewives, and

blueback herring. Coldwater sections in the are suitable for Atlantic salmon and anadromous

trout. This is the only watershed identified by this plan with significant areas of salmon habitat.

Substantial water withdrawals occur to support turf growing and a number of golf courses.

 Significant impacts on resident and stocked fisheries have been observed by RIDFW staff.

R.I. Department of Environmental Management (2002), indicated that several sections of the river

fell below the C classification (less than 5 mg/1 of dissolved oxygen). Most of the watershed has

high water quality

While Denil fishways exist at Potter Hill Dam (Map A.3) and Bradford Dam (A.8), fish passage

efficiency has been poor for shad and river herring. Water flow through broken gates in the dam

on the opposite bank from the fishway draws shad and herring away from the fishway entrance.

Correcting this problem should be given the highest priority. While many areas in the watershed

have suitable anadromous habitat, the following areas are is identified by this plan as the focus for

this watershed. There are eight dams on the mainstem of the Pawcatuck River. The first is

breached and the next two have Denil fishways (Potter Hill A.3., and Bradford, A.8.,

respectively). The habitat suitable for Atlantic salmon, and made accessible by these fishways is

confined to Tomaquag Brook. The most realistic fish passage work providing access to additional

habitat should be directed to the mainstem and Usquepaug/Queen River. The following work

would result in a significant expansion of potential river herring and American shad spawning
Rhode Island Anadromous Restoration Plan

21

habitat making this a more cost effective option than some of the other alternatives. The next dam

upstream of Bradford on the mainstem (Richmond USGS Gaging Station - dam A.13.) is not an

impediment to Atlantic salmon and needs only minor work to allow alosid passage. Carolina Dam

(A.15) is breached and is not an obstruction to fish passage. Fishing Falls Dam (A.16.) will

require removal or a Denil fishway. Horseshoe Falls Dam (A.17.) will require a Denil fishway. 

Kenyon Dam (A.18.) will require a Denil fishway. Usquepaug Dam (A.28.) on the Queen will

require a Denil fishway. This fish passage expansion would provide access to over 1300 additional

acres of habitat, portions of which are suitable for all the target species of this plan.

B.1. Mashaug Pond Watershed

B.1.1. Mashaug and Little Mashaug Ponds (suitable for river herring and white perch) are coastal

barrier lagoons adjacent to Block Island Sound. Because there typically no saltwater intrusion,

salinity levels range from brackish to fresh. Passage into barrier ponds requires either natural or

manual breaching of the barrier beach at least twice annually at appropriate times. Springtime

breaching will allow migrating adult alewives and white perch access to spawning areas and a fall

breach will allow juveniles to exit the system. The technique of manual breaching has been used

successfully for many years at Quicksand Pond in Little Compton. Adult fish stage just beyond the

surf zone adjacent to the Quicksand barrier beach. Sufficient water leaches through the sand to

give the necessary olfactory cues. If the barrier does not breach naturally by April 1st, DFW

personnel have used a back-hoe and bull dozer to remove enough sand to allow the pond to

breach. This manual breach method if employed during calm sea conditions has allowed the

barrier beach to heal itself quickly because sand from the barrier travels only a short distance

offshore. Fall breaching to allow juvenile passage has typically coincided wit fall rain events and

should normally be undertaken by October 1st annually. Using DFW personnel and equipment, this

is a cost-effective fish passage method for this system.

B.2. Ninigret Pond Watershed

Ninigret Pond is another coastal barrier lagoon with a permanent man-made breachway. A

number of small tributaries in the watershed are suitable for anadromous restoration. 

B.2.1. East Pond (suitable for river herring and white perch) is located at the southwest

corner of Ninigret historically supported a substantial spawning population of white perch in the

1960's and early 1970's (pers. observation). Passage could be restored through culvert repair

under East Beach road and stream restoration on either side of the culvert. The habitat is suitable

for both river herring and white perch. Stocking of broodstock is necessary.

B.2.2. King Tom Pond (suitable for river herring and white perch) discharges to the

northern part of Ninigret Pond. Fish passage through a steeppass is fishway placed in a trench in

the earthen dam is recommended. The fishway should be closed seasonally and a method for

juvenile out-migration should be employed. Stocking of broodstock is necessary.

B.2.3. Cross Mills Pond (suitable for river herring and white perch) discharges to the
Rhode Island Anadromous Restoration Plan

22

northern part of Ninigret Pond. Fish passage through a trench in the earthen dam and gravel

parking lot adjacent to the dam, installation of a steeppass, and placement of a concrete box

culvert under Old Post Rd. is recommended. This will bypass the existing spillway and culvert

system. The fishway should be closed seasonally and a method for juvenile out-migration should

be employed. Stocking of broodstock is necessary.

B.2.4. and B.2.5. Factory Brook/Pond (suitable for river herring and sea-run brook trout)

discharges to the northern part of Green Hill Pond (connected to Ninigret). Recommended fish

passage is via steeppass fishway, attached to existing concrete spillway in dam. The fishway

should be closed seasonally and a method for juvenile out-migration should be employed.

Upstream, earthwork is required to move boulders to establish more efficient fish passage.

Vegetation/debris inspections and removal will be required regularly to maintain passage to

Factory Pond. Stocking of broodstock is necessary.

B.3. Trustom Pond Watershed

Trustom and Cards Ponds are coastal barrier lagoons with minimally altered barrier beaches. The

U.S. Fish and Wildlife Service (FWS) has control over a large percentage of land in the watershed

as part of the Trustom Pond National Wildlife Refuge. Additionally Trustom Pond is manually

breached regularly to improve water quality in the pond, enhance diversity, and provide habitat

for piping plovers.

B.3.1. As Trustom Pond (suitable for river herring and white perch) is manually breached

regularly by FWS, fish passage through the barrier beach simply requires coordination between

the RIDEM Division of Fish and Wildlife (DFW) and FWS. Stocking of broodstock is necessary.

B.3.2. If access to Trustom Pond is available, passage to Mill Pond could provide a unique

salmonid research opportunity. The DFW Perryville Trout Hatchery is immediately upstream of

Mill Pond. Effluent from the trout hatchery results in a relatively stable flow into Mill Pond.

Offspring of sea-run brook trout and Atlantic salmon reared to the smolt stage at Perryville

hatchery and subsequently released into the system just prior to breaching of the barrier each

spring could be evaluated as a source of potential broodstock. The preferred estuarine conditions 

identified as suitable for sea-run brook trout (by Bigelow and Schroeder 2002) are not present in

the system, but the simplicity of the experiment makes it a cost-effective opportunity. Placement

of a steeppass fishway in the dam would provide direct access to the hatchery. In the absence of

the fishway, a weir-type trap could be placed downstream of the dam and checked regularly DFW

hatchery personnel.

C.1. Point Judith Pond Watershed

Point Judith Pond is a tidal estuary with a permanent, man-made breachway. Salinity levels

typically range from oligohaline to polyhaline conditions, with little anadromous habitat in the

pond itself.

The Saugatucket River is the major tributary discharging to the northern end of the pond.
Rhode Island Anadromous Restoration Plan

23

This river has been the primary focus for anadromous restoration in the watershed. Two Denil

fishways exist in the system at present. Both fishways have characteristics that result in less-thanoptimal upstream passage efficiency. The Main St. fishway C.1.2., (intended to allow American

shad to pass) has a section steeper than the optimal 1:8 slope. Additionally, the overall fishway

was constructed 6" too low for normal water levels during passage periods. The velocity of the

water in the fishway is higher than optimal for alewife and blueback herring passage, and

impassible for American shad. A downstream passage slot/ramp device is recommended to

minimize juvenile passage mortality.

Downstream juvenile passage at the spillway adjacent to the Palisades fishway C.1.3., is

necessary. An open sloped channel is recommended to minimize juvenile mortality. Upstream

passage efficiency at the gatehouse in the spillway for Saugatucket Pond C.1.4., could be

improved with minor modifications. A deeper and narrower slot would maintain water levels and

improve passage.

Indian Lake would add a substantial amount of habitat with minimal cost. A simple

rearrangement of stones in and below the dam C.1.8., combined with a series of pools (similar to

conditions downstream of the steeppass fishway in the Gilbert Stuart) would allow upstream

passage.

C.2. Narrow River Watershed

Narrow (Pettaquamscutt) River is a tidal estuary with a permanent inlet to Narragansett Bay.

Salinity levels typically range from oligohaline to polyhaline conditions. Alewife spawning has

been observed downstream of the first obstruction. The first obstruction C.2.1. at Gilbert Stuart

Birthplace, is a dam with various water control structures serving the historic grist mill.

Anadromous fish passage is via a man-made stream channel combined with a steeppass fishway.

The system has self-sustaining populations of alewives and blueback herring. Diversions of water

to run the mill for demonstrations and to reduce impoundment levels during periods of high

water, create a significant fish passage and mortality worthy of attention. The diversion of water

attracts upstream migrating fish away from the true fish passage channel into an enclosed area

where the fish are susceptible to stranding, low dissolved oxygen, and predation. A steeppass

fishway for this bypass channel is recommended to correct this problem.

C.3. Wesquage Pond Watershed

Wesquage Pond (suitable for river herring and white perch) is a coastal barrier lagoon in close

proximity to Narragansett Bay. Because there limited saltwater intrusion, salinity levels range

from brackish to fresh. Passage into barrier ponds requires either natural or manual breaching of

the barrier beach at least twice annually at appropriate times. Springtime manual breaching will

allow migrating adult alewives and white perch access to spawning areas and a fall breach will

allow juveniles to exit the system. A cooperative agreement with the Bonnet Shores Fire District

is established to maintain this passage method and should be maintained.
Rhode Island Anadromous Restoration Plan

24

D.1. Annaquatucket River Watershed

The Annaquatucket River has four Denil fishways. The Secret Lake Fishway (D.1.4) is a

functional fishway, but few herring ascend the fishway and take advantage of the available habitat.

Presumably, alewives and blueback herring which ascend fishway D.1.3. detect no attraction flow

from the channel leading to Secret Lake and spawn in Belleville Pond. It is recommended that a

steeppass fishway be placed in the bypass channel (D.1.4A.) adjacent to the Secret Lake Fishway.

This will expose a percentage of fish ascending the Annaquatucket River to attraction flow

resulting in passage into an underutilized habitat. 

D.2. Cocumcussoc Brook Watershed

Cocumcussoc Brook simply needs stones removed at D.2.1 to facilitate passage for herring and

rainbow smelt.

E.1. Hunt River Watershed

This watershed already has two fishways in the first two dams on the mainstem. Unfortunately the

fishways have not allowed river herring passage in the past with maximum efficiency. As of 2002,

these fishways are scheduled for retrofits to enhance river herring passage. This system has high

quality habitat for American shad also, but the Denil fishways are incapable of passing shad, even

with the proposed modifications. This system would be ideal however for anadromous brook

trout if a suitable strain could be located. 

E.2. Bleachery Pond Watershed

While this system has habitat suitable for river herring, the significant height of the first

obstruction results in a low restoration factor as indicated in Table 7.2.1.

E.3. Apponaug Cove Watershed

This system has an existing herring run that could be enhanced by improved fish passage at the

partially passable obstruction.

F. Conimicut Point Watershed

While this system has some water quality concerns, it still has a substantial herring run into

Warwick Pond. The system needs scheduled debris and vegetative removal. 

G. Pawtuxet River Watershed
Rhode Island Anadromous Restoration Plan

25

The Pawtuxet Watershed at over 232 miles2 has plenty of anadromous habitat, but the sheer

number of dams combined with the poor water quality in the lower reaches of the mainstem result

in a low overall ranking. One standout project however, despite the poor water quality would be

to remove the first obstruction on the mainstem. This would be valuable for the stream corridor,

and would enhance stream characteristics as described in the introduction of this report.

H.1. Woonasquatucket River Watershed and H.2. Moshassuck River Watershed

These urban watersheds have local interest in establishing fish passage but the poor water quality

and high number of dams make other watersheds more attractive alternatives.

I. Ten Mile River Watershed

This watershed is a standout for anadromous restoration. Alewives and blueback herring have

been observed spawning in the Seekonk River immediately downstream of the first dam at Omega

Pond. I.1. Members of a local fishing club regularly net the herring and lift them over the dam. In

the mid 1990's river herring broodstock were stocked into the Turner Reservoir above I.3. as an

experiment to evaluate the spawning and rearing habitat. The juveniles were successfully observed

an captured confirming the viability of the system. By putting in 2 fishways and breaching the dam

at I.2. passage would be provided to over 300 acres of habitat.

J. Runnins River Watershed

The Runnins Watershed while small, has the last known native shad run in Rhode Island. Despite

water quality issues in the urbanized watershed, the run persists. Cooperative arrangements with

the state of Massachusetts should be made to protect and enhance the remaining population.

K.1. Mussachuck Creek Watershed

This watershed has a remnant population of anadromous herring that persist despite a collapsed

culvert obstructing passage to formerly accessible habitat. Admirably, the RI Department of

Transportation has made verbal commitments to correct this problem. 

K.2. Prince Pond Watershed

A herring run persists in this system despite heavy recreational fishing pressure on a very small

system. Watershed specific regulations need to be adopted to address this issue.

L. Kickamuit River Watershed

This is high ranking system for herring restoration despite being used as part of a local drinking
Rhode Island Anadromous Restoration Plan

26

water supply. A Denil fishway is already designed for the first obstruction.

M. Almy Brook Watershed

This system already has a herring run into Nonquit Pond. Another section of the system has a 380

acre reservoir suitable for herring. The dam is very large but the habitat size makes it an attractive

alternative.

N.1. Quicksand Pond Watershed, N.2. Tunipus Pond Watershed, N.3. Briggs Marsh Watershed,

and N.4. Long/Round Pond Watersheds are all coastal ponds in close proximity to tidal waters.

An alewife population persists in Quicksand Pond and Tunipus Pond because natural breaches of

the barrier allow spawning access. More attention should be given to Briggs Marsh which now

also breaches regularly.

O.1. Sachuest Point Watershed, O.2. Easton Pond Watershed, O.3. Newport Watershed, and O.4.

Lawton Valley Watershed

Gardiner Pond is a standout for anadromous restoration potential because of its size and close

proximity to tidal waters.
Rhode Island Anadromous Restoration Plan

Appendix B. Fish Passage Methods

B.1. Fishways.

B.1.A. Alaska Steeppass Fishway.

An Alaska steeppass fishway is a cost effective method to provide anadromous fish

passage. It is made of aluminum alloy and is designed to be constructed in a modular fashion. The

device is usually set no steeper than a 1:6 slope in dams with relatively stable flow and relatively

small watershed size. Steeppass fishways are typically used in obstructions with relatively stable

water levels during migration periods. The zone for most efficient passage is indicated by the

shaded ellipse in Figure 1. Costs are typically in the area of $15,000 per vertical foot of dam from

design to completion as of the date of this report (R.Quinn, pers. comm.). If possible, the fishway

should be used on dams with a minimum drainage area of 5 miles2. Target species for passage are

alewives and blueback herring.

Figure 1.
Rhode Island Anadromous Restoration Plan

28

B.1.B. Denil Fishway.

Two types of Denil fishway are considered in this plan. Both are constructed with

concrete walls and floor. Slots are placed in the concrete allowing placement of wooden baffles in

the fishway. The velocity of the water is dissipated sufficiently by the baffles to allow efficient

upstream passage of fish. The zone for most efficient passage is indicated by the shaded ellipse in

Figure 2. Denil fishways are typically used in obstructions with relatively stable water levels

during migration periods. For streams suitable for alewives and blueback herring, a 3 foot wide,

1:6 slope Denil fishway is used. The minimum drainage area for this fishway is 16 miles2. For

streams suitable for American shad, typically a 4 foot wide, 1:8 slope Denil fishway is used. The

minimum drainage are for this fishway is 20 miles2. Costs are typically in the area of $30,000 per

vertical foot of dam as of the date of this report.

Figure 2.
Rhode Island Anadromous Restoration Plan

29

B.1.C. Pool and Weir Fishway.

Pool and weir fishways for the purposes of this plan will be considered a specialty passage

device to be used when other devices are deemed unacceptable during the design phase of a fish

passage project. 

Figure 3.
Rhode Island Anadromous Restoration Plan

30

B.1.D. Slot Fishway.

Slot fishways, for the purposes of this plan, will be considered a specialty passage device

to be used when other devices are deemed unacceptable during the design phase of a fish passage

project. They are designed for obstructions with high variations in flow.

Figure 4.
Rhode Island Anadromous Restoration Plan

31

B.2. Breaching of Dams.

B.2.A. Complete removal.

In the absence of contaminated sediments behind a respective obstruction, this removal

method is the preferred method of restoration by this plan. Complete removal of a dam may

benefit a host of fish and wildlife species in any system rather than simply providing fish passage

for certain freshwater and anadromous species. More typical stream corridor vegetation (both

wetland and upland) can become reestablished, ultimately lowering water temperatures and

improving water quality through shading and attenuation of contaminants respectively. Vegetation

can stabilize floodplains with corresponding reductions in erosion, and sedimentation as well. 

It is recognized that a host of socioeconomic and historic issues must be considered for

any dam removal proposal yet these factors are outside the scope of this plan. Recommendations

for particular fishway designs in this plan are not intended to preclude the consideration of dam

removal first in any restoration effort.

B.2.B. Slots.

Some of the low dams which cannot be removed (i.e.: a U. S. Geologic Survey gauging station

dam) may be appropriate for a permanent or manage fish passage slot. The slots are cut or

constructed into dams to provide sufficiently non-turbulent, reduced velocity water for passage of

fish that do not normally jump to ascend rivers such as shad and river herring. In cases where

water levels are of concern during dry periods, stop logs, boards, and gate designs can be

incorporated to reduce flow and maintain water levels. 

B.2.C. Diversions.

In some cases diverting fish around an obstruction may be a reasonable passage alternative. Many

of the historic dams in Rhode Island have abandoned diversion channels and water control

structures which may be altered to pass fish upstream as is, or combined with one of the other

passage methods. In some cases creating a new diversion around an obstruction may be a more

cost effective alternative than some of the other methods.

B.3. Culverts.

Culverts can obstruct upstream and downstream fish passage in a variety of ways. If the

downstream end of a culvert is high enough above the water during upstream migration periods,

the roadway, trail, railroad bed, etcetera, becomes a barrier to passage no different than a dam. In

other cases, culverts that are too small a diameter can increase the velocity of the water to levels

that impact efficient fish passage. The restrictions can also serve to collect debris and concentrate
Rhode Island Anadromous Restoration Plan

32

predators. The darkness inside of culverts may also hinder fish upstream fish passage due to

behavioral characteristics of the fish. The expense for culvert replacement or new installations

should be borne by whomever needs the fill in and around the particular stream. The preferred

alternative would be to remove the fill where possible.

B.3.A. In-kind replacement.

Method used when failure occurs and passage was not hindered prior to failure. Should only be

used if complete removal or spanning the stream corridor are not available options.

B.3.B. Pre-cast box culverts.

To be used during new construction or when attempting to eliminate an obstruction. The culvert

should be sized large enough to keep water velocities to minimum, and have sufficient depth to

allow upstream and downstream movement of fish throughout the year. Should only be used if

complete removal or spanning the stream corridor are not available options. 

B.3.C. Spanning.

Spanning the stream, avoiding physical alterations to the channel, is the preferred method if a

stream crossing is unavoidable. 

B.4. Special Circumstances.

B.4.A. Barrier Beaches.

Passage through barrier beaches into barrier ponds requires either natural or manual breaching of

the barrier beach at least twice annually at appropriate times. Springtime breaching allows

migrating adult anadromous species access to spawning habitat and emigrating juvenile salmonids

access to marine waters. Fall breaching allows emigrating juveniles alosids to exit the system.

B.4.A.1. Timed manual breaching.

The technique of manual breaching has been used successfully for many years at Quicksand Pond

in Little Compton. Adult fish stage just beyond the surf zone adjacent to the Quicksand barrier

beach. Sufficient water leaches through the sand to give the necessary olfactory cues. If the

barrier does not breach naturally by April 1st, DFW personnel have used a back-hoe and bull dozer

to remove enough sand to allow the pond to breach. This manual breach method if employed

during calm sea conditions has allowed the barrier beach to heal itself quickly because sand from

the barrier travels only a short distance offshore. Fall breaching to allow juvenile passage has

typically coincided wit fall rain events and should normally be undertaken by October 1st annually.
Rhode Island Anadromous Restoration Plan

33

Using DFW personnel and equipment, this is a cost-effective fish passage method for barrier

beaches.

B.4.A.2. Natural breaching.

Natural breaching can occur after a heavy rainfall, during moon tides, during storms, or after any

combination of these events. If the breach occurs at the appropriate time, anadromous species will

take advantage of the fish passage opportunity.

B.4.B. Vegetation and Debris. 

Existing anadromous runs and restored runs need regular inspections to address obstructions

caused by vegetation and debris.

A.4.B.1. Shore-based.

Can be conducted by DFW personnel and volunteers.

A.4.B.2. Vessel-based.

Should only be undertaken by DFW personnel unless special arrangements are made.

B.4.C. Fish Lifts.

No fish lifts have been recommended in this plan. In the event that an effort is initiated to restore

the endangered shortnose sturgeon, Acipenser brevirostrum (Figure 12) in Rhode Island, a fishlift

or some other type of fish passage method will be required in the absence of dam removal.
Rhode Island Anadromous Restoration Plan

34

Appendix C. Life Histories and Habitat Requirements of Target Species

C.1. Atlantic Salmon.

Figure 5.

Atlantic salmon are anadromous, migrating from the ocean to fresh water specifically to

reproduce. Most adults migrate from the ocean to the river in the spring. A smaller number

migrate upriver in early fall. They stop eating when they enter fresh water, living off their body fat

and tissues for up to a year. The adult salmon seek cold water areas to spend the summer.

Spawning typically takes place in October and November. Eggs are buried in prepared

gravelly-cobble areas in streams called redds. Most females lay a total of 7,000 to 8,000 eggs in

two or more redds. Unlike Pacific salmon species, Atlantic salmon do not always die after

spawning, and can return to the ocean. A steady supply of clean, well oxygenated water is critical

to sustain the eggs. The eggs remain in the gravel throughout the winter before hatching in the

spring. Newly hatched salmon, called sac fry, obtain food from their attached yolk sac. The

salmon emerge from the redd, primarily from April to June, when the yolk sac has been

completely absorbed. Feeding activities begin at this time. Salmon fry, approximately one and

one quarter inches long at emergence, quickly set up feeding territories which they defend from

other fish. Growing salmon prefer stream habitat lined with cobble-sized stone and clean, cool

(60-70o F) water that is free of sediment. Fish are found in riffles and along the interface of fast

moving water, under overhanging cover and generally toward the bottom of the water column. 

Fry that have spent their first summer in the stream where they hatched are three to four inches

long by fall and are called parr. After one full year in freshwater, the parr will have grown to a

length of four to six inches. Parr remain in freshwater for a period of one to three years. The

freshwater residence period is largely dependent on growth rate. The fastest growing parr,

usually from warmer, more productive tributaries, spend only one year in freshwater. Slower

growing parr, often from colder, less fertile tributaries, spend three, or rarely, four years in

freshwater. Most parr in the Pawcatuck River basin spend two years in freshwater. During their

first fall, parr may disperse widely from their first summer location to seek new habitat. Parr

destined to leave the freshwater environment the following spring begin a process called

smoltification during the preceding winter. Pronounced physical changes occur during the spring
Rhode Island Anadromous Restoration Plan

35

after salmon reach a size suitable for migration to the sea, six to eight inches or more. These

changes allow juvenile salmon to adapt to life in marine waters. Throughout the smoltification

process a series of behavioral, physiological, and morphological changes occur that transform

young salmon from territorial, bottom-dwelling, freshwater fish to schooling, saltwater fish.

Juvenile salmon leaving for the ocean are called smolts. Smolts lose the dark vertical stripes, parr

marks, on their sides and become bright silver in color. Smolts migrate to Long Island Sound

from April through June. Some smolts may commence pre-smolt movement in the fall to start

their long migration.

Smolts move eastward and begin a long migration northward along the coast after reaching Block

Island Sound. The salmon eventually arrive at waters off of the west coast of Greenland where

they share feeding grounds with other Atlantic salmon from North America and Europe. Most

Pawcatuck River salmon return to spawn after residing in the ocean through two sea winters

(2SW). A few salmon, called grilse, return after spending only one winter at sea (1SW), and

others wait until after their third sea winter to return (3SW). The average 2SW salmon grows

from six inches long and weighing about two ounces as a smolt entering Block Island Sound to

about 30 inches and 10 pounds as a returning mature salmon. Grilse (1SW) average about four

pounds and 3SW salmon often weigh more than 15 pounds.

Adult salmon return to Rhode Island primarily in May and June. In the freshwater environment,

the color of the adult salmon slowly changes from silver to a very dark color. The salmon attempt

to reach their natal streams, where they spend the summer holding in deep, cold pools before

spawning in the fall. From the time they enter the freshwater until spawning, often six months

later, the salmon do not feed; feeding begins after they return to saltwater in the fall or spring.

Atlantic salmon, unlike Pacific salmon, do not die after spawning, though many die as a

consequence of the rigors of the upriver migration, the spawning effort itself, and not feeding for

up to one year while in freshwater. Adults that survive the rigors of migration and spawning are

called kelts. Kelts return to the ocean in late fall or early spring, at which time they regain their

silver color. A small percentage of salmon survive several spawning runs, alternating between

freshwater and marine environments. Repeat spawners and grilse are valuable to the salmon

population for maintaining genetic variability and providing a buffer for all sources (fresh and salt

water) of mortality affecting the predominant 2SW year class. Male parr becoming sexually

mature (precocious) in the freshwater environment insure spawning will occur when sea-run

females are present and sea-run males are absent.
Rhode Island Anadromous Restoration Plan

C.2. American Shad, Alosa sapidissima.

Figure 6.

 

American shad spawning may occur in both tidal and non-tidal freshwater, and the spawning

migration corresponds rising spring water temperatures over 50 degrees in the Pawcatuck

Watershed. Shad spawning runs in the usually extend from the middle of April until early July.

Spawning usually takes place between sunset and midnight Williams and Daborn 1984.

Depending on size, female American shad produce up to 659,000 eggs (Roy 1969).

Shad spawn in river areas dominated by broad flats with relatively shallow water (1-6 m) with

moderate (0.3-1.0 m/s) current (Munroe 2000). Highest survival rates of shad eggs reportedly

occur in those settling over gravel and rubble substrates (Layzer 1974). Fish selected sandy or

pebbly shallows for spawning grounds in the more slowly flowing section of the Annapolis River,

NS (Williams and Daborn 1984). Depending on size, female American shad produce up to

659,000 eggs (Roy 1969). Spawning usually takes place in the evening after sundown (Williams

and Daborn 1984). Eggs are released in open water, where they are fertilized by the males. The

juveniles grow throughout the summer, and leave the watersheds in the fall in response to cooling

water temperatures (Leggett and Whitney 1972).

Eight watersheds have been identified in this plan having areas suitable for American shad

restoration. Of the eight, the Pawtuxet, Woonasquatucket, and Moshassuck Watersheds have

significant water quality concerns. The Pawcatuck and Runnins Watersheds have existing shad

runs with room for improvement. The Point Judith and Hunt Watersheds have existing fishways

incapable of providing shad passage into the available habitat. The Ten Mile Watershed

downstream of the Turner Reservoir is the clear choice for shad restoration.

C3. Alewife, Alosa pseudoharengus and Blueback Herring, Alosa aestivalis

 Figure 7. Figure 8.

Spawning periods in Rhode Island typically range from March through June. Alewives generally

spawn 3-4 weeks earlier than blueback herring, with peak spawning separated by 2-3 weeks

(Jones et al. 1978).

In most Atlantic coast populations, juvenile river herring emigrate from freshwater-estuarine

nursery areas between June and November of their first year of life (Richkus 1975). Fecundity

estimates for alewives ranged from 48,000 to 360,000 in Bride Lake, Connecticut (Kissil 1974).

Alewives spawn in large rivers, small streams, and ponds, including barrier beach ponds.

Spawning substrates include gravel, sand, detritus, and submerged vegetation with sluggish water

flows. Blueback herring spawn in swift-flowing, deeper stretches of rivers and streams with

associated hard substrate (Loesch and Lund 1977) and in slower-flowing tributaries and flooded

low-lying areas adjacent to main streams.

Rainbow Smelt, Osmerus mordax

Figure 9.

Rainbow smelt are anadromous, spawning in freshwater and growing and maturing in estuaries

and coastal waters. In coastal streams, most smelt spawn above the head of the tide. Spawners

usually begin to move into spawning areas before the ice breakup. Spawning usually peaks with

bimonthly spring tides. Peak spawning occurs in late March through mid April in RI. Along the

east coast, smelt spawn at water temperatures of 4.0 to 9.0" C (Clayton 1976). Typically, the

substrate in the spawning area of coastal streams is gravel, with water depths at low tide

of 0.1 to 1.3 m (Murwski et al.1980). According to Clayton (1976), spawning site selection is

influenced largely by water velocity rather than depth or substrate. Adapted from USFWS, 1983.

Sea-Run Brook Trout, Salvelinus fontinalis.

Figure 10.

Some strains of brook trout are adapted to survival in the estuarine portions of costal streams and

rivers. Because the estuary is significantly more productive than typical freshwater brook trout

habit, the fish can attain a much larger size an provide a significant recreational fishing

opportunity.
Rhode Island Anadromous Restoration Plan

40

White perch, Morone americana.

Figure 11.

White perch spawn from April through June in estuaries, rivers, lakes, and marshes. Spawning is

usually in freshwater, but may occur in brackish water also. White perch are fecund compared to

similar-sized fish. The large numbers of eggs enable the white perch to propagate rapidly in

introduced areas.
Rhode Island Anadromous Restoration Plan

41

Shortnose Sturgeon, Acipenser brevirostrum. 

Figure 12.

Shortnose sturgeon are typically anadromous, migrating from the ocean to fresh water specifically

to spawn in the spring. They broadcast their eggs in areas with rubble substrate. Once hatched,

the young fish drift downstream and may eventually swim to brackish water. No specific

watersheds are recommended for sturgeon restoration in this plan.

Appendix D. Description of Strategic Plan Strategies

D.1. Biological Component.

To conduct an anadromous fisheries restoration effort for alosids, broodstock must either be

provided with passage to expand into unused habitat, or they must be physically transported in a

tank and stocked into the new habitat while ready to spawn. This trap and transport method has

been used successfully in Rhode Island for may years.

Anadromous salmonid broodstock are typically in short supply. The restoration method usually

consists of spawning males and females at a hatchery, and stocking either eggs, fry, parr, or smolt

stages into the watershed where restoration is desired. The juveniles imprint on the system and

return as sexually mature adults which are either intercepted for broodstock purposes, or allow to

continue their ascent to habitats where natural spawning can occur.

An additional consideration is finding a source of broodstock. Alosids must either be relocated

from streams already having self-sustaining runs in Rhode Island or be relocated from outside the

state, (usually from another New England state). Typically the fish are provided by the USFWS,

state fisheries agency, or a power generating agency. Salmonids are usually supplied by a federal

hatchery from outside of Rhode Island. Special effort is necessary to locate a strain of

anadromous brook trout.

D.2. Fish Passage Component.

Maximizing fish passage efficiency of existing fishways in existing runs is considered one of the

highest priorities in this plan. Efficient adult passage upstream will result in dispersal of juveniles

over the entire available habit. This will help to maximize future adult returns, provided the

juveniles can exit the streams to marine waters as quickly and safely as possible. It is suggested

that corrections to existing fish passage devices including downstream passage of juveniles be

given the highest priority. These suggestions should also be incorporated into any new design

also.

As monies become available, this plan can be used to decide where work should be undertaken for

new projects. Projects identified by this plan range from simple vegetative removal projects all the

way to restorations of entire watersheds.

American eel, Anguilla rostrata upstream passage for juveniles should be considered in any

anadromous fish passage project. Where possible, passage devices should a component of any

project.

Predators of anadromous species have increased dramatically in recent years. Double-crested
Rhode Island Anadromous Restoration Plan

cormorants, Phalocrocorax auritus in particular aggregate near fishways where alosids are

staging. In systems where restoration is underway, this may significantly impact anadromous

populations. It is recommended that a predator management policy be developed and

implemented particularly in those systems where restoration funding is being used.

It is recommended that recreational harvest of anadromous species be closed in any watershed

which has a restoration effort underway for the respective species. For example: If herring

broodstock are being transported into a particular system, no harvest of those fish or fish

ascending the stream from marine waters should be permitted. The regulation change would

simply require that those areas where it is permissible to harvest herring be listed and close all

other areas.

D.3. Fish Passage Funding.

The following are some web sites of potential anadromous restoration funding.

NOAA Restoration Center - http://www.nmfs.noaa.gov/habitat/restoration/funding.html

National Fish and Wildlife Foundation - http://nfwf.org/programs/5star-rfp.htm

FishAmerica Foundation - http://www.fishamerica.org/content/conservation/fishamerica/

Ocean Trust - http://www.oceantrust.org/

Trout Unlimited - http://www.tu.org/index.asp

American Rivers - http://www.americanrivers.org/

CICEET - http://ciceet.unh.edu/index_new.html

Natural Resources Conservation Service - http://www.nrcs.usda.gov/programs/whip/

D.4. Monitoring.

Monitoring of exiting and new anadromous runs is necessary to evaluate success and diagnose

problems, particularly given the costs of restoration. A restoration project needs to be set up so

decisions can be made using data rather than “tradition” and modifications made in a timely

manner to address problems.

D.5. Marine Survival.

Because American shad, Atlantic salmon, alewives, and blueback herring are migratory, U.S. and

international efforts relating to anadromous fisheries in Atlantic waters need to be supported and

quotas and regulations adhered to.

Regulations need to be established for anadromous species in Rhode Island while in marine

waters, staging for a spawning run. Currently alewives and blueback herring are unprotected
Rhode Island Anadromous Restoration Plan

44

downstream of the “defined freshwater/marine boundary”, but have stringent harvest restrictions

upstream of the defined boundary. This paradox has persisted for years, preventing runs from

reaching their potential.

It is recommended that the recreational harvest of anadromous species be based upon monitoring

data rather than having a statewide blanket regulation. Many of the larger systems could

potentially support a higher recreational harvest, while some of the smaller systems may be having

a large percentage of the total spawning population removed.

D.6. Partnerships.

Many partnerships have developed in recent years with the goal of restoring anadromous species.

This includes a number of federal partners, neighboring states, local interest groups, and private

individuals. These partnerships need to continue and be expanded in order to maximize the

effectiveness of the restoration effort and facilitate the restoration effort. The extreme cost of

even a single fishway warrants commitments of broodstock, design, funding, permitting, dam

owner cooperation, construction performance, volunteer monitoring, and more.

Fishways provide outstanding educational opportunities. It is recommended that some of the new

Denil fishways that are constructed in the future incorporate viewing windows in the

turning/resting pool when safely accessible for viewing by the public either supervised or

unsupervised. The windows could also be used for upstream passage counts either visually or

remotely with an infrared camera/video monitoring device.

D.7. Updates and Revisions.

This plan needs to be continually refined and updated as time passes as restoration efforts

commence and as research dictates and watershed characteristics change.

Appendix E. Glossary of Terms.

alosid For the purposes of this report, any of the genus Alosa, including American

shad, alewife, and blueback herring.

anadromous Fish that begin their juvenile life in freshwater, emigrate to marine waters

to complete their adult growth, and migrate back to freshwater to spawn

(i.e. shad, salmon). 

attraction flow Moving water allowing migrating adult fish to achieve proper orientation in

the water column for upstream passage. Fish passage devices typically

provide means of attraction flow to help fish locate the entrance. It’s

possible to have counterproductive attraction flow which draws migrating

fish away from fish passage devices. 

baffle Device used in fishway structures to reduce velocities of flowing water to

levels sufficient to allow upstream passage of fish. 

broodstock Adult, sexually mature fish used to produce eggs and milt or in the case of 

stocking efforts, trapping and transporting adult fish engaged in a spawning

migration and relocating them in suitable habitats in another area. Juveniles

produced from transplanted broodstock will imprint on the new system,

and return as spawning adults.

catadromous Fish that complete their adult growth in freshwater, but migrate to

saltwater to spawn (i.e. American eel).

extirpation Local extinction of a population.

juvenile For the purposes of this plan: The freshwater life stage of any anadromous

species and is not yet sexually mature.

mesohaline Moderately brackish water with low range salinities (from 5-18 parts per

thousand). 

migratory Movement of anadromous species from one habitat to another on a

seasonal basis at a particular life stage..

oligohaline Moderately brackish water with low range salinities (from .5-5 parts per

thousand).
Rhode Island Anadromous Restoration Plan

81

ppt Parts per thousand (used as a measurement of salinity).

polyhaline Pertaining to waters with salinities of 18-30 parts per thousand.

salinity The salt concentration of water, measured in parts per thousand (ppt). 

salmonid From the family Salmonidae. For the purposes of this report, any Atlantic

salmon, anadromous brook trout, anadromous brown trout, and wild

freshwater populations of brook trout.

smoltification Physiological changes in juvenile Atlantic salmon allowing survival in saline

water.

spawning habitat Areas with characteristics sufficient to induce adult anadromous species to

spawn and conditions suitable for egg survival and incubation.

rearing habitat Areas sufficient to provide juvenile anadromous species with conditions

necessary to survive downstream migratory life stage. 

watershed Zone defined at the periphery by topography or physical barriers that cause

surface water and ground water to drain to a particular body of water.
