The community is invited to McHenry County Green Drinks from 5 to 7 p.m. Wednesday, Oct. 1, at Duke's Alehouse & Kitchen, 110 N. Main St. in Crystal Lake. The Fox River is a great resource for northeastern Illinois residents, but it has been listed as impaired by the Illinois Environmental Protection Agency.

Steve Pescitelli of the IDNR will discuss the current status of fish communities, how fish are used as a stream quality indicators, and how conditions on the river affect fish and the aquatic ecosystem. He will also describe the results of recent dam removals and how they have benefited fish in the Fox River watershed.

There will be a free drawing for CDs of music about the Fox River.

Pescitelli has been a stream specialist with the Illinois Department of Natural Resources since 1994. He is responsible for monitoring fish communities, management of sport fisheries, permit review, watershed planning, habitat and stream restoration, outreach and education.
