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

A project to collect and analyze water quality data for Little River, San Gabriel River, and Big Elm Creek as a first step toward developing a watershed protection plan.

Background

The San Gabriel River and Big Elm Creek are major tributaries to the Little River. Big Elm Creek is on the 303(d) list as impaired for excessive levels of 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 is implementing education and outreach programs. It is examining the features of the watershed to determine the sources of pollution causing impairment of the streams. This characterization will determine reductions in pollution needed for the streams to meet water quality standards again. The findings may provide the basis for a watershed protection plan.
