Datum of gage changed from NGVD 1929, 1973 adjustment to NAVD 1988, 2001 adjustment, on Oct. 1, 2008. New datum is 3.12 ft below previous datum.
The reservoir outflow structure consists of six gates. Discharge through the gates are computed using provisional gate-opening ratings provided by USACE and are based on reservoir elevation and the opening of each gate. These ratings and computations have not been calibrated based on USGS discharge measurements. Total outflow from the reservoir is captured at downstream USGS station 08073100 - Langham Ck at Addicks Res Outflow nr Addicks, TX, where data are collected and published using standard USGS methods. Any additional drainage that enters the channel between the reservoir outlet structure and 08073100 is limited to surface runoff.
