Keeping the River Clean: Consider Compost

Little known fact: Yard waste such as cut grass that ends up in your local storm drain can adversely affect water quality in the San Diego River and other local waterways.


As it decomposes, rotting yard waste releases nutrients that promote the growth of algae, which can lower the river's dissolved oxygen level. It can also promote bacteria growth. The result is a triple-whammy of low dissolved oxygen, high nutrients and elevated  bacteria levels that can cause problems for fish and other creatures in the river. Also, these stagnant conditions make the river less attractive for recreational use.

Residents can prevent yard waste from reaching waterways  by adding leaves and clippings to a compost pile or placing it in a curbside yard waste recycling container.

You can make a backyard compost pile by mixing grass clippings with leaves. Compost can return nutrients to the soil and help conserve water. Click here to watch a video on how to make your own compost.
