Temperature is one of the most important environmental factors controlling the distribution and behavior of fishes. Fish often inhabit a specific thermal niche where they optimize physiological performance. Although water temperature requirements and preferences vary according to individual species and life stage, of interest and relevance to us is continual engagement in field projects investigating thermal preferences and tolerances exhibited by species of interest (e.g. Chinook and Coho Salmon).  

We have performed water temperature analyses in support of various research projects since 2008. Currently a multi-year thermal monitoring study within the numerous watersheds throughout Alaska and will require water temperature data to help understand how thermal conditions may influence salmonid distribution and abundance. 

Live temperature monitoring available soon for the following locations: Kenai River, Upper Moose Creek, Ugashik River, and Egegik River.

The Fish and Aquatic Conservation program leads aquatic conservation efforts for the U.S. Fish and Wildlife Service. We are committed to tackling the nation’s highest priority aquatic conservation and recreational challenges to conserve, restore, and enhance fisheries for future generations.


Welcome to our Southern Alaska Office! We have dedicated staff working with partners to conserve fish and wildlife via habitat restoration and conservation, fish assessment and management, technical assistance, cost-sharing, funding, and outreach.
Established in 1971, our office works to support and sustain salmon recovery, improve fisheries, prevent fish habitat degradation fragmentation, restore fish habitat, and control invasive species on the Kenai Peninsula and in western Alaska.

Fish and Wildlife Conservation Offices specialize in providing fish population information. This data is critical for managing fisheries and assessing management strategies. Data is collected by tagging and recapturing fish, monitoring angler harvest, and even tracking the DNA they behind leave in...
