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.

Rainfall Disclaimer Rainfall monitoring sites operated by the USGS in Texas are strictly for operational purposes. Precipitation data, if available for this station, are temporary and will only be displayed for 120 days. Precipitation data will NOT be available for retrieval following the 120-day display period. The temporary classification means that documented routine inspections and other quality assurance measures are not performed that would make the data acceptable for archival, retrieval, or future use in general scientific or interpretive studies.
