For specific information about conservation pool elevation, current storage and percent full, access these data maintained by the Texas Water Development Board for major Texas reservoirs here.
Data are tidally affected -- Astronomical tides cause significant cycles of approximately 24.84 hours at this site. Because a different portion of the 24.84-hour tidal cycle is averaged in successive daily (24-hour) computations, a systematic secondary oscillation, unrelated to basin hydrology and having a period of about two weeks may be apparent in daily data.
This station managed by the Houston Field Unit.
