Notes

2013-06-19: The vertical datums of gauge, conservation pool and dead pool elevations for this lake have been adjusted to NGVD29-0.05ft.

Inks Lake: 95.1% full as of 2022-11-27

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.
