Santa Margarita Watershed Nutrient Initiative – Stakeholder Group – Project Clean Water

Santa Margarita Watershed Nutrient Initiative – Stakeholder Group

The Santa Maragrita Watershed Nutrient Initiative РStakeholder Group, composed of a broad range of stakeholders with diverse interests, was formed to address nutrient issues in the Santa Maragrita River Watershed.

The Group currently is focused on the initial phase of this project, Phase 1, which targets the development of the methods that are used to prepare and implement a workplan to use a nutrient numeric endpoint (NNE) methodology to understand nutrient impacts to the SMR Lagoon.

This work is a follow-on effort to the San Diego Lagoons Investigative Order (R9-2006-0076) (Lagoon Order) and subsequent workplan developed jointly by the San Diego Regional Water Quality Control Board (RWQCB) and stakeholders in 2006 and is funded with Proposition 84 IRWM grant funds . Future phases, yet to be funded, will focus on collecting comparable data sets on nutrient loading and transport processes, developing the model(s) needed to establish NNE targets and bringing a common understanding of seasonal impact of nutrients on the beneficial uses.

Through a collaborative, inclusive, and regional process the Santa Maragrita Watershed Nutrient Initiative РStakeholder Group hopes to set regulatory targets that are based on state of the science techniques to ensure the biological, chemical and physical integrity of the Santa Margarita River and its tributaries are protected.

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