Pinto Lake catchment TMDL addressing cyanobacterial blooms

Information

On 16 July 2020, the Central Coast Regional Water Quality Control Board adopted a total maximum daily load (TMDL) for phosphorus and an associated implementation strategy for improving water quality in Pinto Lake, located in Santa Cruz County. Reducing phosphorus loading to Pinto Lake is anticipated to reduce the frequency and severity of cyanobacteria blooms. The TMDL implementation strategy describes how the Water Board’s regulatory mechanisms, and non-regulatory actions will address phosphorus loads from various sources in order to attain water quality standards.
