FY23 BAHG Recommendation

The BAHG recommends the FY23 Budget and Workplan as described in the FY21-23 

Triennial Budget and Workplan for consideration by the TWG.

The BAHG recommends the following revisions to the FY23 Workplan as prioritized

below and as funds become available (see Table 1): 

1. Continue JCM-West (Project Element G.6),

2. Continue TRGD (Project Element H.2) with two sites instead of one,

3. Begin the Grand Canyon portion of the Water Quality Synthesis (proposal in development),

4. Investigate Aquatic Vegetation Removal Pilot in Lees Ferry to reduce brown trout habitat 

(proposal in development),

5. Continue Sandbar Vegetation Expansion (Project Element C.1) with two surveys instead of 

one,

6. Continue Streamflow and Sandbar Modeling to include silt and clay (Project Element B.5).

Cost share

Continue JCM-West (Project 

Element G.6)

1* Identifies drivers of 

humpback chub in 

western Grand Canyon

$250k • 2018

• 6-7 yrs

• Yes

This is a conservation measure.

Halfway through the study.

Yes No No

Continue TRGD (Project 

Element H.2) with two sites 

instead of one

2* Identifies drivers of 

rainbow and brown trout 

in Ferry

$67k • 2011

• Longterm monitoring

• Yes

Evaluates impacts of experiments 

(Bugflows, TMFs, HFEs) on 

rainbow and brown trout.

Yes No No

Investigate Aquatic Vegetation 

Removal Pilot in Lees Ferry to 

reduce brown trout habitat 

(proposal in development)

4

Possible control measure 

for brown trout, still in 

development

TBD • New

• Being developed

• No

Increasing brown trout 

population may impact 

humpback chub and other native 

fish.

No Yes No

Continue Sandbar Vegetation 

Expansion (Project Element C.1) 

with two surveys instead of one

5

Mapping vegetation on 

sandbars with the 

sediment group

$22k • 2014

• Longterm monitoring

• No

Measures what is reducing beach 

area: vegetation encroachment 

vs HFEs/operations

Yes Yes No

Begin the Grand Canyon water 

quality synthesis (proposal in 

development) 3

Modeling informs 

appraisal level studies re: 

temperature & DO 

modification

$125k • New

• 2 years

• Yes

This is an AMWG 

recommendation. Appraisal level 

studies are being done soon. 

Risks of warm water releases are 

high.

No Yes Reclamation 

funding Lake 

Powell portion, 

AMP funds Grand 

Canyon

Continue Streamflow and 

Sandbar Modeling to include silt 

and clay (Project Element B.5)

6

Improves accuracy for 

sediment modeling

$64k • 2021

• 1 year

• No

Would inform nutrients and 

turbidity dynamics on fish and 

foodbase.

No Yes First two years 

partially funded 

outside AMP

*These two projects were specified in the FY22 BAHG, TWG, and AMWG recommendation for funding in FY23.
