The Keweenaw Peninsula watershed, located in Michigan's Upper Peninsula, covers an area of approximately 2,582 square miles. The region receives significant amounts of snowfall, with an average annual snowfall of over 200 inches. This snowpack contributes to the watershed's hydrology, which is largely reliant on surface water runoff from snowmelt and precipitation. Surface water in the Keweenaw Peninsula watershed is dominated by a number of large lakes and reservoirs, including Lake Superior and the Portage Lake reservoir. These water bodies are home to a variety of fish species, including trout, salmon, and walleye. Water quality in the watershed is generally good, although there are some concerns about elevated levels of nutrients and contaminants in certain areas. Climate data suggests that the Keweenaw Peninsula watershed is experiencing a warming trend, with increased average temperatures and shorter winter seasons. This trend is likely to have significant impacts on the region's hydrology and ecology in the coming decades.
