Description:

The Auke Creek weir, located in Juneau, Alaska, is a permanent fish counting structure that allows for near complete sampling of downstream and upstream migrant salmonid species. The weir has been in operation in its current configuration since 1980, creating one of the richest long-term series of anadromous salmonid data in the North America. Data include abundance, migration timing, age, length, and weight of trout and commercially important salmon species, as well as creek temperature, and gauge height. We summarize data collected in 2022 and report historical trends from 1980 to 2022. Since 1980, the temperature of Auke Creek has shown a significant increase. Coinciding with environmental changes, several biological attributes of Auke Creek salmonids have also been changing, such as migrations occurring earlier. Despite changing biotic and abiotic conditions, the abundance of most species and populations of Auke Creek salmonids has remained stable.
