DEC and DOH Issue Recreational Use Advisory for Ischua Creek in Cattaraugus County

ALBANY, N.Y. (August 28, 2025) - The New York State Department of Environmental Conservation (DEC), in coordination with the New York State Department of Health (DOH) and Cattaraugus County Health Department, is investigating a potential organic waste discharge to Ischua Creek and a significant fish and wildlife die-off.

Out of an abundance of caution, the public is advised to avoid all contact with Ischua Creek downstream of Franklinville, including recreational uses such as fishing/fish consumption, boating, and swimming, until further notice.

At this time, there is no indication of impacts to public drinking water supplies. Local water systems have been notified and are taking precautionary monitoring steps.

Protecting the health of New Yorkers and the environment is the top priority and DEC field teams are monitoring water quality, tracking the movement of the discharge downstream, and assessing impacts to aquatic life. Additional updates will be provided as information becomes available.
