This page provides analysis, based on Reclamation 2019 Proposed Action, of current and historical temperature conditions for fish using only observed data. Actual pre-season and in-season management decision processes are complex employing multiple sources of observed data, models, and forecasts. For further information, see the Thresholds section.
