Little River, San Gabriel River, and Big Elm Creek: Characterizing the Watershed

Background

The San Gabriel River and Big Elm Creek are major tributaries to the Little River. Big Elm Creek does not meet water quality standards for bacteria. All three water bodies have concerns for chlorophyll-a, nitrate, depressed dissolved oxygen, orthophosphorus, and total phosphorus.

Project Description

This project created a stakeholder group for the watershed and implemented education and outreach programs. Features of the watershed were examined to determine the sources of pollution causing impairment of the streams. This characterization determined reductions in pollution needed for the streams to meet water quality standards again. The findings will provide the basis for a watershed protection plan for the Big Elm Creek watershed.
