Implementation of a Nutrient Total Maximum Daily Load (TMDL) for Big Bear Lake

An amendment to the Basin Plan to incorporate a Nutrient Total Maximum Daily Load (TMDL) for Big Bear Lake was approved by the Regional Board on April 21, 2006, by the State Water Resources Control Board on April 3, 2007, by the Office of Administrative Law on August 21, 2007 and by the U.S. Environmental Protection Agency on September 25, 2007. The adopted TMDL requires dischargers to meet specific implementation tasks and compliance dates.

Dischargers in the Big Bear Lake watershed have formed a Big Bear Lake TMDL Task Force (TMDL Task Force). The TMDL Task Force members are working jointly to implement requirements of the TMDL. TMDL Task Force members include the following agencies/parties: UNITED STATES DEPARTMENT OF AGRICULTURE, FOREST SERVICE (“FOREST SERVICE”), CALIFORNIA DEPARTMENT OF TRANSPORTATION (“CALTRANS”), San Bernardino County Flood Control District (“FLOOD CONTROL”), the COUNTY OF SAN BERNARDINO (“COUNTY”), the CITY OF BIG BEAR LAKE (“CITY”), BIG BEAR MUNICIPAL WATER DISTRICT (“WATER DISTRICT”), BIG BEAR MOUNTAIN RESORTS (“RESORTS”), the SANTA ANA REGION REGIONAL WATER QUALITY CONTROL BOARD (“REGIONAL BOARD”), and the Santa Ana Watershed Project Authority (“SAWPA”).  The REGIONAL BOARD and SAWPA are appointed as non-voting, non-funding PARTIES of the TMDL TASK FORCE.

The TMDL Task Force has submitted several plans and schedules to meet specific requirements of the TMDL.  Regional Board approved these plans and schedules at Board meetings.

Big Bear Lake and Rathbun Creek Sediment TMDLs

After receiving additional data, we are evaluating delisting Big Bear Lake for sediment. We are also reviewing additional data to determine whether the beneficial uses of Rathbun Creek are impaired due to sediments.
