Bureau of Reclamation’s Reform Act (RRA) in the Central Valley, AAR conducted a fishery resources assessment that included: (1) Determining fishery resources habitat and population conditions; (2) Statistical analysis of potential changes that could have occurred as a result of implementation of the RRA; and, (3) Determining the impacts of the RRA on fishery resources, including winter-run Chinook salmon, Delta smelt, and striped bass.

CENTRAL VALLEY PROJECT IMPROVEMENT ACT, CALIFORNIA — IMPACTS ON FISHERY RESEOURCES

As part of the U.S. Bureau of Reclamation’s Programmatic EIS for the Central Valley Project Improvement Act, AAR analyzed the impacts of past, present, and proposed restoration projects Central Valley Chinook salmon, Central Valley steelhead trout, striped bass, American shad, and white sturgeon.

CLIFTON COURT FOREBAY, CALIFORNIA — SEDIMENT MPACTS OF DREDGING ON STRIPED BASS

AAR assessed the potential impacts of different concentrations of suspended sediment on striped bass, as a result of dredging in Clifton Court Forebay in the San Joaquin River Delta.

LITTLE HASTINGS ISLAND CONSERVATION BANK — REHABILITATION MEASURES FOR THREATENED AND ENDANGERED FISH SPECIES

In connection with the proposed Little Hastings Island Conservation Bank in the Sacramento-San Joaquin Delta, AAR is evaluating restoration measures that would provide additional habitat for fishery resources. Fish species of interest include: Central Valley steelhead; Central Valley Chinook salmon; delta smelt; North American green sturgeon; longfin smelt; Sacramento splittail; white sturgeon; and, river lamprey

SAN JOAQUIN RIVER WATERSHED, CALIFORNIA — CHINOOK SALMON SMOLT QUALITY STUDY

Dr. Alice Rich designed and supervised a Chinook salmon smolt quality study in the San Joaquin, Merced, and Tuolumne rivers. Physiological smolt and stress indicators were monitored in emigrating fish during the parr-smolt transformation. The data were then used to assess smolt quality at different sites (the rivers, the State Pumping Facility, fish trucked to Antioch) as the fish emigrated from the system. Smolt quality was correlated to survival, using tag return data.

SAN JOAQUIN COUNTY. CALIFORNIA — HABITAT CONSERVATION AND OPEN SPACE PLAN

In connection with the development of the San Joaquin County Habitat Conservation and Open Space Plan, AAR conducted a fishery resources assessment that included: (1) Analysis of existing information; (2) Identification of life stage requirements of fish species of special importance; (3) Analysis of impacts of various landuses (e.g., urban development, activities undertaken by public agencies, agriculture, water diversions, etc.) on fishery resources; (4) Transformation of data into GIS format (ArcInfo); and, (5) Identification of measures to mitigate for the loss of fishery resources and/or habitat.

SAN JOAQUIN RIVER WATERSHED , CALIFORNIA — THERMAL IMPACTS ON CHINOOK SALMON AND STEELHEAD

The San Joaquin and its tributaries are listed as impaired by high water temperatures, under the State’s Clean Water Act Section 303 (d). Dr. Alice Rich provided expert witness testimony, on behalf of the California Department of Fish and Game, on the impacts of the existing thermal conditions within the San Joaquin River and its tributary rivers.

SAN JOAQUIN RIVER WATERSHED, CALIFORNIA — IMPACTS OF A HOUSING DEVELOPMENT ON THREATENED AND ENDANGERED FISH SPECIES

As part of the environmental process for the proposed River Islands at Lathrop Project in the Sacramento-San Joaquin Delta, AAR has been contracted to address fishery resources issues that include the following Tasks: (1) Water quality and water temperature monitoring; (2) Designing fish screens; (3) Designing and implementing on-site biological monitoring; (4) Designing a Fish Monitoring Plan to assess any future impacts of the project on the fish species; (5) Section 7 Consultation with the agencies; and, (6) Periodic Fishery Resources Technical Reports.

CALAVERAS RIVER, CALIFORNIA — WATER QUALITY IMPACTS OF BOAT DOCKS ON SALMONIDS

As part of the environmental process for the Brookside Housing Project, AAR provided the following: (1) Section 7 Consultation with agencies to assess the potential impacts of the project on Chinook salmon, steelhead, delta smelt, and Sacramento splittail; (2) Designing and implementing a three-year water quality and water temperature monitoring effort; and, (3) Designing and implementing on-site biological monitoring during construction

DELTA WETLANDS PROJECT, CALIFORNIA — THERMAL IMPACTS ON SALMONIDS

In a project in the Sacramento River System in which water would be stored for later discharge, AAR provided an analysis of the thermal effects of the project on Chinook salmon and steelhead. Dr. Alice A. Rich provided testimony, on behalf of the California Department of Fish and Game at the State Water Resources Control Board.

AMERICAN RIVER, CALIFORNIA — INSTREAM FLOWS, WATER TEMPERATURES, AND GROWTH OF ANADROMOUS FISHES

AAR assisted Sacramento County in a multi-year dispute over the effects of water diversion from the American River Bay by the East Bay Municipal Utility District for domestic uses. To address the relationship between flows in the American River and thermal requirements of anadromous fishes, AAR designed and conducted laboratory and field physiology studies on Chinook salmon, steelhead trout, and American shad. The results of the studies were presented to the State Water Resources Control Board by Dr. Alice A. Rich.

HABITAT CONSERVATION AND MANAGEMENT PLAN, BEALE AIR FORCE BASE, CALIFORNIA — SALMONID SURVEYS

In connection with revising a Habitat Conservation and Management Plan that addressed natural resources issues at Beale Air Force Base, AAR conducted snorkeling surveys for Central Valley steelhead and fall-run Chinook salmon in Dry Creek on the Base.

YUBA RIVER, CALIFORNIA — THERMAL IMPACTS OF REDUCED FLOWS ON CHINOOK SALMON AND STEELHEAD

AAR analyzed the thermal impacts of a water diversion on Chinook salmon and steelhead in the Yuba River for the California Department of Fish and Game (DFG). The results of the analysis were presented to the State Water Resources Control Board Hearings by Dr. Alice A. Rich.

PG&E’S DE SABLA-CENTERVILLE PROJECT, CALIFORNIA — THERMAL IMPACTS ON SPRING-RUN CHINOOK SALMON

Dr. Alice Rich provided testimony on the existing thermal conditions within the Project Area. The testimony included: (1) analyzing the physiological effects of water temperatures on the various life stages of Spring-run Chinook salmon; and, (2) analyzing the effects of water temperature-related mortality (both sublethal and lethal) on the population of Spring-run Chinook salmon in the Butte Creek and West Branch Feather River Systems
