All About Riffles

Riffle

At river-edge forest preserve sites like LaBagh Woods in Chicago or the Village Green in Northbrook, Ill., you can spot these critical riffles in the water. Friends' executive director, Margaret Frisbie, explains how riffles benefit aquatic life here.

In addition to enjoying the scenery, you can help restore LaBagh Woods at gullyfixing workdays through out the spring and summer. Register here
