2013-02-08: The rating curve for OH Ivie Reservoir has been updated and replaced with data from the Colorado River Municipal Water District.

O. H. Ivie Reservoir: 20.0% full as of 2017-11-22

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, and (2) 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.

Percent Full is based on Conservation Storage and Conservation Capacity and doesn't account for storage in flood pool.
