Description

1. Supplemented and analyzed hourly water temperature collected at our long-term monitoring sites at 18 locations in the Sprague River sub-basin.
2. Used water temperature data to estimate the range of potential spawning dates, and the associated dates of emergence, for spring and fall Chinook in the Sprague system.
3. Used water temperature data to evaluate suitability of thermal habitats for summer rearing by juvenile Chinook salmon.
4. Compared water temperature analyses to two remote sensing data sets from FLIR projects that measured surface water temperature throughout the Sprague drainage in 1999 and 2007.

Project Benefit

With the signing of the Klamath Basin Restoration Agreement and Hydroelectric Agreement and the amendment of the Klamath Basin Anadromous Fish Reintroduction Plan the return of Chinook salmon is imminent. This project will help provide guidance for Chinook salmon stock selection and reintroduction strategies, by providing important insights (e.g. timing and distribution in relation to potential limiting factors) into potential Chinook reproductive patterns in the Sprague. This information will be useful in guiding initial reintroduction studies designed to evaluate and select stocks for reintroduction.

Key issues addressed by habitat attribute research
Based on thermal regimes in the Sprague River sub-basin, what spawning timing and distribution might be possible for adult spring and fall Chinook, and what emergence timing and distribution might result? This is an important threshold question, and the answers provided by this study will help guide stock selection and initial active research into stock performance when reintroduction begins.
