Tijuana Estuary Tidal Restoration Program

The Tijuana Estuary Tidal Restoration Program (TETRP) is a large multi-phased wetland restoration program located within the Tijuana River National Estuarine Research Reserve. The primary objective of TETRP is to restore valuable habitat processes that have been lost and to increase the exchange of water in a tidal cycle. This will enhance tidal flushing, improve water quality and control sedimentation to ensure the estuary is a sustained natural habitat. Learn more about TETRP.

White Pelicans are becoming more common to San Diego and the Tijuana Estuary. Historically they wintered in the Salton Sea. As the fish supply in the Salton Sea dwindled they started seeking other sources to the West, including many of the lakes in San Diego.
