Tulare Lake Subbasin (TLS) Probation

On April 16, 2024 the State Water Resources Control Board (State Board) voted to place the Tulare Lake Subbasin (TLS) on Probation. In its resolution (Resolution No. 2024-0012), the State Board outlined the deficiencies of the 2022 TLS GSP that must be addressed. The Mid-Kings River GSA is coordinating with the TLS to define a path forward. The resolution also includes requirements regarding reporting and metering of groundwater extraction for persons within the TLS.
