recent changes

2015-09-24: Based on new information obtained from the U.S. Army Corps of Engineers, the effective date range for seasonal conservation pools was changed from 1974 - present (2015) to 2004 - 2010.

Lake Kemp is 98.6% full as of 2016-07-26

The elevation-storage rating curve used to produce the storage hydrograph is made of two segments: (1) the segment up to the conservation pool top (below the red line) is based on measured data, while the segment in the flood pool (above the red line) is an extrapolation from the first segment and shouldn't be relied upon for flood storage information.
