Proposed Minimum Flows at Iron Gate Dam

Regardless of hydrologic conditions, daily minimum flows at Iron Gate Dam must be met or exceeded to meet the needs of coho salmon in the Klamath River and are defined in the table below.  Further details of how IGD flows are calculated in Fall/Winter Operations and how EWA is determined and distributed in Spring/Summer Operations is described in the 2013 Biological Opinion for the Klamath Project.
