| Summary: | This project characterized stream temperature regimes in the Bristol Bay, Kodiak Island, Cook Inlet, Copper River, and Prince William Sound regions to better understand thermal habitats for spawning and juvenile salmon. We aggregated 1,691 summertime stream temperature time series from 420 monitoring locations across southwestern and southcentral Alaska and calculated a suite of metrics related to the magnitude, frequency, duration, timing, and variability of stream temperatures. We categorized streams into one of six different thermal regimes using metrics including temperature range, stability, and timing. Thermal regimes represent a gradient of cold to warm habitats with Groups 1 and 6 experiencing the coldest temperatures, and 2, 3, 4, and 5 ranging from colder to warmest. Group 1 had the latest timing of maximum stream temperatures and Group 6 had the most stable stream temperatures. A comparison of stream thermal regimes among regions showed that cold habitats with later timing of maximum temperatures, ... |
