Abstract

The removal of the Otsego City Dam on the Kalamazoo 

River at Otsego, Mich., is under consideration by the Michigan 

Department of Environmental Quality and the city of Otsego. 

The historical discharge of papermill waste containing polychlorinated biphenyls from sources upstream from the dam 

has led the U.S. Environmental Protection Agency to designate 

the Kalamazoo River from Morrow Dam near Comstock to its 

mouth near Saugatuck as a Federal Superfund site. The papermill waste is concentrated in organic sediment and kaolinite 

clay, with the sediment containing as much as 94 milligrams 

per kilogram polychlorinated biphenyls. This contaminated 

sediment could move if the dam is removed; therefore, it is 

necessary to estimate the characteristics and configuration of 

the sediment before removal plans begin.

Data from augered sections and sediment cores show that 

the current Otsego City impoundment sediments were deposited in two distinctly different sedimentary environments:

(1) lacustrine sediments consisting of organic-rich silt and 

clay, fine to medium sand, and some gravel deposited in a 

repetitive, cyclic fashion related to former stream velocities 

when the Otsego City impoundment water levels were

2-4 feet higher (1880s-1960s), and from downstream movement of lacustrine sediments during the removal of the 

upstream Plainwell Dam superstructure in the 1980s; and

(2) more recent (1980s-2002) coarse-grained alluvium 

deposited on top of the lacustrine sediments. The volume of 

instream sediment contained within the Otsego City impoundment is estimated to be about 457,270 cubic yards. This 

estimate is based on the composite thicknesses of the lacustrine deposits and overlying alluvium, which were determined 

to contain PCBs, and does not include bank or flood-plain 

deposits.

Introduction

From the mid-1800s to the early 1900s, four dams were 

constructed on the Kalamazoo River between the cities of 

Plainwell and Allegan, Mich. (fig. 1). The Otsego City Dam 

was built in the 1840s in an effort to create a freight business 

on the Kalamazoo River (Dalrymple, 1972). The original dam 

was 5 ft high and contained a lock for the passage of barges, 

canoes, or rafts. In the 1880s, a papermill was built at the dam 

site and remains in operation to date (2002). Over the years, 

the dam has been rebuilt and repaired, providing a continuous 

industrial water supply for the mill. 

Beginning in the 1950s, the storage capacities of the four 

impoundments were reduced by an influx of papermill waste 

rich in polychlorinated biphenyls (PCBs) from upstream industrial sources (Malcolm Pirnie Engineers, 1958). The primary 

industrial activity associated with PCB releases to the Kalamazoo River was the recycling of carbonless copy paper containing PCBs as an ink solvent (Camp Dresser & McKee, 1999). 

Kalamazoo-area papermills that de-inked or re-pulped paper 

from 1957 to 1971 incorporated the PCB-laden ink solvent 

in their waste discharge. These paper wastes also included 

kaolinite clays, which were found in the impoundment sediments to contain concentrations of PCBs as high as 94 mg per 

kg (Blasland, Bouck, & Lee, 1994). During the 1960s, water 

levels within three of the four impoundments were lowered, 

exposing previously inundated contaminated sediments. In 

response to the lowering of water levels, the river began to 

erode the sediments and transport them downstream, but much 

of this waste clay remains impounded behind the Otsego City 

Dam. If the dam is removed, transport and deposition of the 

impounded materials could alter the downstream characteristics of the stream channel and increase the PCB exposure 

potential to stream biota. 

The presence of PCBs in the Kalamazoo River has 

prompted the U.S. Environmental Protection Agency (USEPA) 

to designate the reach from the city of Kalamazoo to its outlet 

into Lake Michigan as a Federal Superfund site. The Michigan Department of Environmental Quality-Environmental 

Response Division (MDEQ-ERD) and the city of Otsego 

are considering the removal of the Otsego City Dam (Dennis Eagle, MDEQ-ERD, oral commun., 2000). Removal of 

the structure will return this part of the Kalamazoo River 

to run-of-the-river flow and improve aquatic habitat in the 

reach. Removal of the dam can also result in problems such as 

movement of sediment downstream and migration of invasive 

species from the Great Lakes to headwater areas. Because

additional impoundments downstream from the project area 

will remain in place, migration of invasive species should not 

be a problem; however, movement of contaminated sediments 

is a concern. The release of these sediments may result in the 

spread of additional contaminants into the downstream environment (Doyle and others, 2003). 

In the summers of 2001-2002, the U.S. Geological Survey (USGS), in cooperation with MDEQ-ERD and USEPA, 

conducted channel surveys of instream sediments in the 

Otsego City impoundment on the Kalamazoo River. Rheaume 

and others, 2002, reported on the volume, character, and size 

distribution of the instream sediments in the surrounding 

Plainwell, Otsego, and Trowbridge impoundments. 

Purpose and Scope

This report (1) describes the results of the USGS 

and MDEQ-ERD data-collection effort in the Otsego City 

impoundment, (2) relates this information to the depositional 

history of sediments behind the dam, and (3) provides an estimate of the volume of instream sediment in the Otsego City 

impoundment. Maps of sediment distribution and thickness, 

as well as tables of lithologic descriptions and particle-size 

analysis results, are provided.

Hydrologic Setting

The city of Otsego lies in the Kalamazoo River Valley in 

the southwestern part of Michigan (fig. 1). This river valley 

was a large, glacial meltwater channel, formed in the interlobate zone between the Michigan and Saginaw glacial-ice lobes 

during the late Pleistocene Epoch (Leverett and Taylor, 1915). 

As the Michigan Ice Lobe retreated to the west, broken upland 

ridges consisting of poorly bedded cobble, sand, and gravel, 

developed (Monaghan and Larson, 1984). These ridges mark 

the drainageways or channels of a much larger river than present that flowed during this glacial epoch (Deutsch and others, 

1960). As ice blocks melted and outlets lowered, the Kalamazoo River was rejuvenated and developed its modern-day size 

and course (Martin, 1958). 

Currently (2002), the main stem of the Kalamazoo River 

originates in Calhoun County at the confluence of the North 

and South Branches and flows northwestward for 123 mi to 

Lake Michigan near the city of Saugatuck. The river has meandering channels and point bars, and flows through a broad, 

well-defined flood plain. The Kalamazoo River has a drainage area of more than 2,000 mi2

 with more than 400 mi of 

tributaries, including Portage Creek, a known source of PCBs 

(Stratus Consulting, Inc., 2000). A USGS streamflow-gaging 

station has been operating on the Kalamazoo River at Comstock, Mich., from 1931 to present (2002). The drainage area 

at Comstock is approximately 1,010 mi2. The mean annual 

flow for the 70-year period of record is 896 ft3/s. A maximum 

daily mean flow of 6,830 ft3

/s was recorded on April 8, 1947, 

and a minimum daily mean flow of 185 ft3/s was recorded on 

August 7, 1934 (Blumer and others, 2001). The Kalamazoo 

River from Kalamazoo to Plainwell has an average slope of 

2.6 ft/mi, whereas the average slope from Plainwell to Allegan 

is 4.9 ft/mi (Malcolm Pirnie Engineers, 1958). Historically, the 

river has been impounded for hydroelectrical and other industrial purposes where the gradients are higher (Blasland, Bouck 

& Lee, Inc., 1994). 

Methods of Investigation

This study was conducted to determine the volume, 

character, and size distribution of sediments in the Otsego 

City impoundment. The sediment volume estimate is for the 

instream reach from the Otsego City Dam to the foot of the 

Plainwell Dam (approximately 1.8 mi upstream) and does not 

include bank or flood-plain deposits. 

Description of Transects

Eighty-five transects were established in the impoundment (fig. 2a). Transect spacing on the main stem of the Kalamazoo River was based on the river width at the Otsego City 

dam (fig. 2a). Transect G1 was positioned as close to the dam 

as safety would allow. Transects G2, G3, and G4 were spaced 

upstream at intervals of one river width apart. Transects G5, 

G6, and G7 were spaced at intervals of two river widths apart. 

Transects G8, G9, and G10 were spaced at four river widths 

apart, providing data into the end of the backwater for the 

current (2002) impoundment. The distance from the dam to 

transect G10 is approximately 1.2 mi. The end of this backwater was indicated by increased river velocities, riffles, and 

debris islands. Transects in all other channels of the Otsego 

City impoundment (A, B, C, D, E, F, H, I, and J) generally 

were placed at the beginning, ending, or splitting of channels 

(fig. 2). 

Reference points were established at each transect by driving a steel fence post into the right or left bank, close to the 

edge of the water. Altitudes of the top of the reference points 

were surveyed to 0.1 ft using Real Time Kinematic Global 

Positioning System (RTK GPS) equipment. Altitudes of bank 

height and water surface were measured from reference points 

as transects were completed. 

A 3/16-in. steel cable tagline, painted at 5-ft intervals, 

was stretched across the river perpendicular to the channel at 

each transect. As the transect data were collected, latitudelongitude coordinates were taken at both ends of the tagline 

and at the left and right banks by use of a hand-held GPS unit. 

For locations along the main stem of the Kalamazoo River 

within the impoundment (G1-G10), the transect width between 

the banks was divided into 15 equal sections for measurements 

of water depth, water velocity, and sediment thickness

(appendix 1). In all other river channels (A, B, C, D, E, F, H, 

I, and J), spacing of data points across transect lines generally 

was set at 10-ft intervals. The coordinates for individual data 

points were interpolated from the bank coordinates. 

Hydrologic Setting 3
Collection of Data Points and Sediment Cores

Data points (water depth, water velocity, and sediment 

thickness) were collected across each transect in the impoundment. Water depths and water velocities were measured by 

standard USGS methods (Rantz and others, 1982) using a 

boat-cable measuring device equipped with an A-reel, a 15- or 

30-lb weight, and a Price AA standard current meter. 

Hand augering along transect lines was performed in 

order to determine sediment thickness. Thickness of the 

impoundment sediment was obtained by boring with a 1-ftlong by 11⁄2- in.-diameter auger bit with 4-ft extension pipes. 

The depth of the impoundment sediment that overlay the 

pre-dam alluvium (altitude prior to dam construction) was 

indicated when the auger could no longer be advanced. This 

contact between the pre-dam outwash and the post-dam sediments was distinct, and could be determined easily by a grinding that could be heard and felt when the auger bit contacted 

the underlying coarser material of cobbles and stones. 

Core samples were collected at one point along selected 

transects, generally where impoundment sediments were thickest (fig. 2b). Cores were collected at depths where lithology 

changed by use of a stainless steel 2-in.-diameter sediment 

bore. Changes in sediment texture and color were observed in 

the field. A total of 164 samples from 76 core locations were 

collected and sieved at the Michigan State University Department of Geography Geomorphology Laboratory by use of U.S. 

Standard Sieves. 

Estimation of Sediment Volume

In order to estimate the volume of the instream sediments, a series of grids was generated by use of a geographic 

information system (GIS). Grid surfaces for water depth and 

post-dam sediment were interpolated on the basis of augerpoint data by use of TOPOGRID in Arc/Info 8.2. Contours 

were generated from the interpolated grid surfaces. The 

contours were modified, redrawn manually on the basis of

point. This comparison allowed for a root mean squared error 

(RMSE) by

The RMSE provides an error estimate for the grid cells 

corresponding to the auger-points, which were used as the 

control, and is a measurement of how well the interpolated 

surface fits the observed auger-point data. In the absence of 

additional data, these points are believed to be representative 

of the grid as a whole. As outlined in the “National Standard 

for Spatial Data Accuracy,” the RMSE can be used to determine the accuracy using the equation for data with normally 

distributed error (Federal Geographic Data Committee, 1998). 

A summary of the maximum residuals, RMSE, and accuracy 

are listed in table 1.

Sediment Characteristics within the 

Otsego City Impoundment

Stratigraphic relations among the sediments within and 

flanking the channel vary as a function of distance upstream 

from the dam. The area inundated by the impoundment during 

the different time periods is reflected by the sediment stratigraphy and can be divided into an upper zone and a lower zone. 

The upper zone contains the reach flooded by the dam 

when it was fully operational at design-pool levels (2-4 ft 

higher than present). Backwater from the impoundment

extended 1.6 mi upstream from the Otsego City Dam or 0.2 mi 

below the Plainwell Dam (fig. 2). As water levels behind the 

Otsego City Dam were lowered (late 1960s), previously inundated backwater sediment was exposed. In the upstream reach 

of the historical impoundment, lacustrine deposits remain in 

the floodplain but have been eroded completely in the present-day river channel. At these locations, increased slopes and 

river velocities have exposed very coarse pre-dam alluvium, 

which in some places has been overlain by recent (1980s2002) sand and gravel.

The lower zone is the 1.2-mi extent of backwater created by the present-day dam (approximately from the dam to 

transect G10; fig. 2). Three stratigraphic units can be identified 

in the lower zone. These units are (1) outwash and alluvial 

cobble, gravel, and sand deposited before dam construction, (2) interbedded lacustrine clay, silt, and sand deposited 

and redeposited when water levels were 2-4 ft higher in the 

impoundment, and (3) sand and gravel deposited after water 

levels in the impoundment were lowered. 

Lithologic descriptions of the cores are given in 

appendix 2. Particle-size distributions for the samples are presented in appendix 3. A summary of the sediment thicknesses 

at core locations through the main stem of the river within the 

study reach is given in table 2.

Pre-dam Outwash and Alluvium

As glacial ice retreated from the study area 10,000 to 

15,000 years ago, meltwaters flowed westward through continually lowering outlets (Martin, 1958). The glacial Kalamazoo 

River was much larger than the present river, eroding large 

volumes of sediment as it cut through outwash and lake plains 

to form the Kalamazoo River Valley. After the end of the 

Pleistocene epoch, the volume of water discharged through 

the Kalamazoo River diminished greatly, leaving the river to 

occupy only a small part of its outwash and alluvium-filled 

ancestral river valley (Deutsch and others, 1960). For thousands of years, the Kalamazoo River meandered across the 

Kalamazoo River Valley, reworking the pre-dam outwash and 

alluvium. This pre-dam material is identified easily and consists of cobbles, coarse gravel, and lesser amounts of medium 

to coarse sand. 

Lacustrine Deposits

For approximately 80 years, the Otsego City Dam 

impounded water at levels 2-4 ft higher than present impoundment levels (fig. 3a). Lacustrine material deposited in the 

impoundment consisted of interbedded, organic-rich silt 

and clay, fine to medium sand, and some gravel deposited 

cyclically in response to changes in river velocities during 

high and low flows. Previous work has shown that elevated 

PCB concentrations are contained in the lacustrine deposits 

(Weston, Inc., 2002).

Judging from streambank elevations, the thickness of the 

lacustrine material was as much as 10.5 ft thick in the Otsego 

City impoundment by the mid-1960s. In the late 1960s, water 

levels were lowered in the Otsego City impoundment (fig. 3b), 

causing some of the previously deposited lacustrine sediments 

to be eroded and transported downstream. Demolition of the 

upstream Plainwell dam superstructure (Camp Dresser & 

McKee, 1999) in the mid-1980s resulted in appreciable channel erosion of lacustrine sediments in the Plainwell impoundment (Rheaume and others, 2002). The mobilized sediments 

subsequently were redeposited in channels of the Otsego City 

impoundment. This aggradation resulted in the river becoming 

more braided as the main channels were filled and new channels that were lower in elevation were cut (fig. 3c). 

Auger-point data and sediment cores collected in 2001-02 

showed that the thickness of the lacustrine deposits in the main 

stem of the present Kalamazoo River (fig. 3d) ranges from 0 

to 7.5 ft in the Otsego City impoundment (table 2); however, 

thicknesses as great as 11.2 ft were observed in the side channels of the impoundment (appendix 1).

Post-drawdown Alluvium

From an examination of sediment cores, the most likely 

period of channel stabilization was the 1980s. After the channels stabilized, sand and gravel began to aggrade within the 

impoundment from upstream sources. These recent coarsegrained alluvial deposits lie directly over the lacustrine 

deposits and, for the most part, consist of sands and gravel 

with lower PCB concentrations than those in the lacustrine 

sediments. Sediment samples of these deposits collected by 

the USEPA in 2001 contained PCB concentrations less than 

30 ppm (Weston, Inc., 2002). These post-drawdown alluvium 

deposits are not PCB free because PCBs continued to be 

released into the channel from erosion of flood-plain deposits, slumping streambanks, and upstream channel-bed scour 

(Camp Dresser & McKee, 1999). Auger-point data and sediment cores collected in 2001-2002 showed that the thickness 

of the post-drawdown alluvium ranges from 0 to 3.0 ft in the 

main channel of the Otsego City impoundment (table 2).

Impoundment Bathymetry

Altitude of the water surface, present-day streambed, and 

base of the impoundment sediment was determined at each 

data point along transect lines. Altitudes for each layer were 

established by level and rod survey (appendix 1). Water depths 

in the impoundment during low flows ranged from 0 to 10 ft, 

with average depths being less than 7.5 ft (fig. 4). 

Sediment Thickness and Volume in the 

Impoundment

As inferred from sediment-thickness data gathered near 

the dam, the streambed bottom of the pre-dam river was at 

altitudes 7-10 ft lower than the bottom of the present-day 

impoundment (fig. 5). Particle-size analysis of core samples 

collected in the impoundment indicate that the pre-dam river 

consisted of a cobble-gravel bottom and stable cobble-lined 

banks.

When water levels were lowered in the Otsego City 

impoundment during the mid-1960s, dam lacustrine sediments were eroded, transported, and redeposited. Subsequent

demolition of the upstream Plainwell Dam in the mid-1980s 

resulted in the movement of lacustrine sediments in the Plainwell impoundment. As these sediments moved downstream, 

they filled in channels in the Otsego City impoundment. New 

channels were formed, and increased river velocities began to 

transport and deposit coarser grained sands and gravel from 

upstream. 

Westjohn (1997) showed that both the coarse-grained alluvium and fine-grained lacustrine deposits in a river channel are 

capable of being transported downstream if a dam is removed. 

For this reason, the post-drawdown alluvium and dam lacustrine deposits are considered as one unit in the Otsego City 

impoundment and are reported together in the volume estimate 

as total cubic yards of instream sediment (fig. 6, table 3). 

The estimated total volume of instream sediment in the 

Otsego City impoundment is 457,270 yd3. Sediment thickness 

ranges from 0 to 11.2 ft, and the average thickness is 3.7 ft 

over the 3,291,470-ft2 impoundment (appendix 1). Approximately 56 percent (258,000 yd3

) of the total 457,270 yd3 of 

sediment in the impoundment is in the main-stem channel 

between the Otsego City Dam and Plainwell Dam (transects 

G1-G10, A13-A5, A2-A1); and 44 percent is in the side channels (B, C, D, E, F, H, J, & I). Of the 258,000 yd3

 in the main 

channel, 93 percent is located in the lower half of the main 

channel between the dam and transect G10 (figs. 2A and 6).

Summary

The Michigan Department of Environmental Quality 

(MDEQ) and the city of Otsego, Mich. are considering the 

removal of the Otsego City Dam. Removal of the structure 

will return part of the Kalamazoo River to run-of-river flow 

and improve aquatic habitat in affected river sections. However, because of PCB contamination in the sediment, the U.S. 

Environmental Protection Agency (USEPA) has designated the 

Kalamazoo River from the city of Kalamazoo to its outlet into 

Lake Michigan as a Federal Superfund site. Removal of the 

dam may result in a mobilization of contaminated sediment 

with adverse consequences on the downstream environment.

The U.S. Geological Survey (USGS), in cooperation 

with MDEQ and USEPA, studied the volume, character, 

and size distribution of instream sediments in the Otsego 

City impoundment on the Kalamazoo River in 2001-2002. 

Water depth and sediment thicknesses were measured along 

85 transects. Sediment cores were collected at 76 sites in 

the impoundment. Sediment-depth profiles and particle-size 

analysis of core samples formed the principal basis for an 

interpretation of the depositional history and lithology in the 

Otsego City impoundment. The following are major findings 

and conclusions of the study:

•The pre-dam streambed has been well defined upstream 

from the Otsego City Dam. The pre-dam streambed 

easily is identifiable and is composed of very coarse 

outwash and alluvium material: cobbles, coarse gravel, 

and lesser amounts of medium to coarse sand. All of 

the sediment-depth measurements for this study terminated in this coarse pre-dam outwash and alluvium.

•Two types of deposits are present: (1) lacustrine deposits 

that accumulated after the dam was constructed and 

(2) recent (1980s to present) alluvial deposits that accumulated on the lacustrine deposits after the impoundment levels were lowered.

•Lacustrine deposits consist of interbedded, organic-rich 

silt and clay, fine to medium sand, and some gravel. 

Auger-point data and sediment cores within the main 

channel show that the thickness of the current (2002) 

lacustrine deposits ranges from 0 to 7.5 ft in the

Otsego City impoundment.

•Post-drawdown alluvium deposits are medium to coarse 

sand and gravel with traces of silt and clay. This 

coarse-grained surface is related to increases in gradient and velocity, which took place after water levels 

were lowered at the Otsego City Dam in the 1980s. 

These alluvium deposits lie directly on remaining 

instream lacustrine deposits. Thickness of the postSummary 13
drawdown alluvium ranges from 0 to 3.0 ft in the main 

channel of the Otsego City impoundment.

•The combined volumes of post-dam lacustrine deposits and post-drawdown alluvium are estimated to be 

457,270 yd3. Total sediment thickness ranges from 0 to 

11.2 ft, and average thickness is 3.7 ft over an area of 

3,291,470 ft2. Approximately 56 percent (258,000 yd3) 

of the total 457,270 yd3 of sediments in the impoundment is within the main-stem channel between the 

Otsego City Dam and Plainwell Dam; 44 percent is 

within the side channels. Of the 258,000 yd3 in the 

main channel, 93 percent of that is located in the lower 

half of the main channel.

Appendix 3. Particle size of selected sediment samples from cores collected in the Otsego City impoundment on the Kalamazoo 

River at Otsego, Mich.--Continued

[Particle sizes are tallied by using Wentworth size classes, in which the size doubles with each class (0.063, 0.125, 0.25, 0.5, 1, 2, 4, 16 mm); >, greater 

than; < less than or equal to; mm, millimeters; --, no data.]
