Santa Ana Sucker Conservation Team

SAWPA has been working with other public agencies and organizations in the effort to complete the entire Santa Ana River Trail and Parkway, also known as the Santa Ana River Crest-to-Coast Trail, and add parkway elements to the river.

In 1998, members of a group of concerned public agencies from throughout the Santa Ana River Watershed began meetings, which led to the formation of the Santa Ana Sucker Conservation Team. Early on, the U.S. Fish & Wildlife Service (USFWS) and the California Department of Fish & Wildlife joined the effort. SAWPA hosts the ongoing meetings and serves as the administering agency for the effort.

In April, 2000, the USFWS listed the Santa Ana sucker as a threatened fish species. The Team has funded research, field surveys and in-stream habitat projects directed at recovery of the fish.

Under the cooperative agreement, the recharging parties have agreed to the following tasks:

Prepare a summary of the amount & quality of imported water recharged in each groundwater management zone during the previous three-year period.

Prepare a report at six-year intervals that provides a projection of ambient water quality in each groundwater management zone for the subsequent 20 years.

An agreement among the following agencies and the RWQCB was executed on July 18, 2009.

On August 29, 2019, Amendment No. 1 to the Cooperative Agreement was executed, which modified the reporting time intervals for the recharge reports and groundwater modeling.

On October 25, 2019 the parties to the Cooperative Agreement agreed to fold the work tasks, to be undertaken by Agreement parties, under the Basin Monitoring Program Task Force, as a subcommittee of the Task Force.

Santa Ana Sucker Fish Habitat Survey (Riverwalk)

The primary purpose of the Riverwalk is to survey the status of the Santa Ana sucker fish’s habitat. Conducting a regional survey is useful because the data gathered can be integrated with other habitat and fish surveys. It allows different entities, who may collect other data, to compare their data to the Riverwalk survey and track trends.

The Riverwalk Atlas provides a map-based summary of the data collected during the annual survey event.

The updated Riverwalk Atlas with the most recent results from the 2021 Riverwalk will be released soon. For the 2006-2018 Atlas, please find the document here. For questions, please contact iachimore at
