Management Threshold Forecasts
These short-term forecasts predict the probability of exceeding low flow or high temperature (hoot owl) management thresholds over the next 1-4 weeks. Forecasts are based on real-time streamflow and water temperature data from U.S. Geological Survey (USGS) streamgages, combined with species-specific flow and thermal thresholds. More about how it works.
