Lake Erie Watershed (Pennsylvania)
Lake Erie Watershed is a major drainage catchment in northwestern Pennsylvania, consisting of lands with direct runoff and sub-watersheds with waterways that flow into Lake Erie and Presque Isle Bay from Crawford and Erie counties, as well as from New York. The watershed is part of the Lake Erie Basin.
Averill Creek is also called 41.5 Mile Run
Cemetery Run begins north if E 38th near Millcreek proceeding through Roma Park before continuing to the lake by Lakeside Cemetery, with many portions run underground due to development or through culverts.
Some Pennsylvania lands have surface runoff that drains directly into Lake Erie. 24 such stretches of land can be identified.
Erie International Airport is located in the largest of these direct runoff zones, west of the City of Erie, between Walnut Creek and Cascade Creek sub-watersheds. The airport's Master Plan includes a water quality section in its Environmental Baseline Study (Chapter 3, Section 3.07).
The master plan positions the airport in Lake Erie Watershed, 9,000 feet (2,700 m) north of Walnut Creek Sub-watershed, 12,000 feet (3,700 m) west of Cascade Creek Sub-watershed, and five miles (8 km) west of Mill Creek Sub-watershed, which is part of the Presque Isle Bay Watershed. The plan notes that Wilkins Run, a tributary (sic) that drains directly into Lake Erie, is situated 1,000 feet (300 m) west of the airport.
Storm drainage is identified in the master plan as the main potential water pollution danger. Construction and deicing operations require federal permits and extensive measures are taken to contain and process the runoff properly. A report detailing these measures is included at the end of the airport's master plan, entitled Airport Drainage Master Plan.
