Black-Presque Isle
Watershed Hydrology
The Black Presque Isle Watershed (HUC 04020101) covers an area of 1,585 square miles in the Upper Peninsula of Michigan. The hydrology of the watershed is dominated by the presence of numerous streams and wetlands, which ultimately drain into Lake Superior. The region experiences heavy snowfall during the winter months, with snowpacks averaging over 100 inches in some areas. Surface water in the watershed is typically characterized by clear and cold water, with a low nutrient load. The watershed is also home to several large reservoirs, which are used for hydroelectric power generation and recreational activities. Interesting climatic facts include the presence of a strong lake-effect snow effect due to its proximity to Lake Superior, as well as a general trend of increasing temperatures and decreasing snowfall over the past several decades.
