Capabilities
Gomez and Sullivan's scientists and biologists focus
on: instream flow studies, water level management studies, aquatic habitat evaluation, water quality monitoring, fish population surveys, impact
assessment, entrainment studies, fish passage efficiency and design, sediment
investigations, and habitat improvements plans.
- Fisheries and Fish Passage
- Gomez and Sullivan's staff has a diverse
background with regard to conducting and managing fisheries and fish
passage investigations. Our project experience includes:
evaluation of fish community structure and habitat use; instream flow
evaluation and setting; management of angler (creel) surveys; assessment
of fish entrainment and survival; assessment of intake protection
alternatives; and evaluation of diadromous and resident fish passage at
dams and hydroelectric facilities. Our staff is also familiar with
the latest fisheries technologies and has strong technical expertise
with fish collection, fish identification, and tagging techniques.

- Water Quality
- Gomez and Sullivan's staff has over 20
years experience in water quality analysis and research.
We have designed a variety of water quality monitoring and modeling
studies. Gomez and Sullivan staff have successfully studied the
effect of dams and impoundments on dissolved oxygen, temperature,
nutrients and mercury methylization.

- Instream Flow Studies
- Gomez and Sullivan has experience utilizing
various instream flow setting techniques such as: hydrology based
(Range of Variability Analysis, Indicators of Hydrologic Alteration,
USGS Streamstats), standard-setting (Tennant, Aquatic Base Flow,
Wetted Perimeter) and incremental (Instream Flow Incremental
Methodology, Physical Habitat Simulation and Demonstration Flows) to
determine appropriate flow regimes for aquatic biota. We
have conducted PHABSIM based instream flow studies on over 18 rivers
throughout New England and New York. In addition, we have
completed several demonstration flow studies in consultation with
agencies and NGOs, where flows were visually observed and ranked in
terms of habitat quality for the species/life stages of
interest.
