1 The Elevation Trigger is invoked when Hinckley Reservoir elevation falls below the 10% historical low level. The elevation trigger is 1222 feet in May, 1198 feet October 15 to December 31 and linearly interpolated from 1222 feet on May 31 and 1198 feet on October 15.
2 "Normal" Hinckley Reservoir elevations for a given date are based upon the average of 59 years of daily Hinckley Reservoir elevation data (1942-1979 and 1987-2007).
3 cfs is the abbreviation for cubic feet per second.
4 The 2012 Operating Diagram establishes the rate of release of water from Hinckley Reservoir based upon varying reservoir levels throughout the year. Image of the 2012 Operating Diagram.
5 The Inflow Trigger is invoked when the 30-day running average Hinckley Reservoir inflow is below 300 cfs.
