Did you know that the Great Lakes are the biggest freshwater source in the world? Lake Erie is the most productive for fishing of all the Great Lakes. Your support helps make our streams clean, clear and healthy so they can support this complex ecosystem. By donating to PCS, you help us reach our goals of restoring rivers that lead to Lake Erie beaches that promote fishable and swimmable conditions for generations.

Area covered by the Great Black SwampIt’s no secret that the Northwest Ohio region is relatively flat. But, did you know that this same land was once covered by a vast swamp? Spanning about 100 miles across and 25 miles wide, most of our area used to exist as a network of marshes, forests and wetlands. 

Across Ohio, approximately 10% of our once-abundant wetland habitat remains. In pre-industrial times, Northwest Ohio was home to the Great Black Swamp, a large stretch of wetlands and woodlands that housed a wide variety of plants and animals. As more European settlers arrived in the region, they began to drain the swamp to make the land more suitable for agriculture. While this resulted in some of the most productive farmland in the country, it came at the expense of our region’s wetlands.

February 2 is World Wetlands Day. It is important to recognize this day as Northwest Ohio was once home to 1,500 square miles of wetlands. Wetlands improve water quality, control erosion, store floodwater, plus they're biodiversity hotspots. Although smaller in scale now, these crucial wetland habitats still remain in our area, both original and restored. You can find wetlands coastal areas along Lake Erie, including birding hotspots like Magee Marsh Wildlife Area and Maumee Bay State Park, as well as farther inland in the wet prairies of Oak Openings.

This World Wetlands Day, what are we celebrating? A lot! Wetlands act as storage facilities for water during and after large rain events, helping to prevent flood damage and erosion. They are capable of absorbing and holding substantial amounts of water, and then slowly release it over time. Wetlands also act as natural filters for the water that enters their systems. As water is retained in the wetland, suspended sediments are able to drop out and nutrients, such as those coming from fertilizer, are consumed by plants and microorganisms. Eventually, the water is released into the ground below or into a nearby waterway, with better water quality than when it entered the wetland.  Wetlands are also extremely productive biologically, acting as homes for many different plants, as well as insects, frogs, turtles, fish, mammals, and as important stopovers for migratory birds.

Partners for Clean Streams Inc. is striving for abundant open space and a high quality natural environment; adequate floodwater storage capacities and flourishing wildlife; stakeholders who take local ownership in their resources; and rivers, streams and lakes that are clean, clear and safe
