The west branch of Catfish Run is impaired by Urban Runoff/Storm Sewers and Siltation. The large circled commercial district along Route 88 and Baptist Road is located within the Catfish Run watershed. Storm water runoff from this large area finds its way into Catfish Run.
Pollutants on the large parking areas and roads, including salt in the winter, grease and oil from cars, anything dropped by shoppers, even atmospheric deposition from industrial plants finds its way into Catfish Run during rain events. During the summer, runoff from these large impervious surfaces can be much hotter than the waters of Catfish Run. This increases water temperature in the stream. Many aquatic organisms are not able to cope with this intermittent increase in temperature.
The Ice Skating rink parking lot can be seen in the lower right of the photo along Hundred Acre Drive. It is also a large impervious surface and contributes to the problem. The parking lot is much larger than necessary to handle the parking needs of the Skating Rink and the VIP Zone. Your job is to act as citizen civil engineers. You will study the runoff problem at the parking lot site, perform a biological, chemical and physical assessment of Catfish Run and make recommendations for a redesign of this area to decrease the runoff entering the stream.
