SMRWMA Regional Clearinghouse

The Santa Margarita River Watershed Management Area Regional Clearinghouse

The Copermittees in the Santa Margarita River Watershed Management Area (WMA) work cooperatively to implement the requirements of the Regional MS4 Permit (Order No. R9-2013-0001, as amended by R9-2015-0001 and R9-2015-0100) issued by the California Regional Water Quality Control Board, San Diego Region.

This Regional Clearinghouse provides public access to all of the plans, reports, maps, and supporting information required to implement the Regional MS4 Permit. The Water Quality Improvement Plan (WQIP) is the overarching watershed plan, whereas the Jurisdictional Runoff Management Program (JRMP) documents provide more details regarding implementation.

Principal Permittee: Riverside County Flood Control and Water Conservation District

Typically, the WMAA is presented as an appendix to each watershed’s WQIP; however, there is also a regional component to the WMAA. The Santa Margarita Watershed Management Area Analysis is currently undergoing discussion.

In the development of the WQIP, meaningful public consultation will ensure the transparency, efficiency and ultimately the effectiveness of the WQIP. Consequently, interested members of the public will be able to participate in the development of the WQIP in the following ways:

1.Notification: Using the link below, request to be notified of key WQIP development milestones and activities. Notices will principally include upcoming meetings and availability of documents for review.
2.Participation: Participate in calls for data and the formulation of objectives and approaches. There will be a minimum of 2 calls for data.
3.Consultation: A Consultation Panel (i.e., Consultation Committee) was formed to specifically seek the opinions of key interested and affected groups to guide the development of a comprehensive WQIP.

California Environmental Data Exchange Network (CEDEN)

Southern California Stormwater Monitoring Coalition (SMC)

California BIGHT Program

The Santa Margarita River Water Quality Improvement Plan (WQIP) is a requirement of updated stormwater regulations adopted by the Regional Water Quality Control Board (Regional Board) according to Order No. R9-2013-0001, as amended by Order Nos. R9 2015-0001 and R9-2015-0100.

The ultimate goal of the WQIP is to protect, preserve, enhance, and restore water quality of receiving water bodies. These improvements in water quality will be accomplished through an adaptive planning and management process that identifies the highest priority water quality conditions within the watershed and implements strategies to address them. Watersheds are based on geography and do not follow jurisdictional boundaries. As a result several Agencies are working together to create a WQIP which allows them to address both regional and jurisdictional water quality improvement goals.

For more information please contact Matt Yeager at (951) 955-0843 or MYeager@Rivco.org

Monitoring data used in the development of the WQIP can be found on the California Environmental Data Exchange Network (CEDEN) website. For monitoring and assessment data files please refer to the Annual Monitoring Reports. Additional information and data is also available on the California Monitoring Coalition (SMC) website and the California BIGHT Program website.

GIS Data used in the development of program documents and reports for the SMR WMA were obtained from multiple sources and compiled into the files posted below.

The Santa Margarita Watershed Nutrient Initiative – Stakeholder Group, composed of a broad range of stakeholders with diverse interests, was formed in 2012 to address nutrient issues in the Santa Margarita River Watershed. This Stakeholder Group, with support from a Technical Advisory Committee, is working through a collaborative, inclusive, and regional process, using state of the science techniques, to develop regulatory targets and monitoring programs, and to recommend management approaches to ensure that the biological, chemical, and physical integrity of the Santa Margarita River and its tributaries are protected.

Technical investigations were initiated in 2006 by the San Diego Lagoons Investigative Order (R9-2006-0076). Phases I and II of follow-up grant-funded technical work developed models to apply a nutrient numeric endpoint methodology to evaluate nutrient impacts to the SMR Lagoon, collected comparable data for nutrient loading and transport processes, and developed regulatory targets for the Lagoon. Through evaluation of the model simulations and discussions during the collaborative development of the targets, the stakeholders have achieved a greater understanding of the seasonal impact of nutrients on the beneficial uses. Phase I and II efforts were conducted from 2011 to 2018 and were supported by Proposition 84 IRWM grant funds.

In early 2019, the group initiated Phase III of the Project, which extends the work conducted for the Lagoon in Phases I and II to explore a range of biostimulatory targets that are protective of beneficial uses in the Santa Margarita River main stem under the present climate conditions and under climate change and/or extreme climate scenarios. Phase III will also identify potential restoration actions to improve biointegrity and reduce eutrophication, and will calculate load and waste load allocations required to meet the proposed biostimulatory targets. The technical work in Phase III is being funded by the San Diego Water Board.

If you are interested in participating in this process, please contact the Chairperson of the Initiative Group via e-mail.
