through the Great Lakes waterways into the St. Lawrence River, which flows northeasterly into the Gulf of St. Lawrence on the Atlantic Ocean. Ecology Environmentalists were concerned about preserving the river when the Crandon mine was proposed near a tributary of the river. The Crandon Mine was purchased by the Sokaogon Mole Lake Chippewa Band tribe in 2003 to prevent development that would adversely affect the river. The campaign to stop the Crandon Mine on the Wisconsin's Wolf River was the result of successful coalition-building efforts amongst Wisconsin's indigenous groups, environmentalists, and rural citizens. Restoration of sturgeon spawning Two dams on the upper Wolf River block sturgeon from returning to their historic spawning grounds at Keshena Falls on the Menominee Reservation: the Shawano Dam 125 mi. upstream from Oshkosh, Wisconsin and Balsam Row Dam 5.5 miles above the Shawano Dam, both constructed in the late 1800s. The result was that for over 100 years no sturgeon (or other fish) spawned in the waters above the Shawano Dam. Starting in 2012, the WDNR in conjunction with the Menominee tribe, implemented a sturgeon capture and relocation program to populate the river above the dams with mature sturgeon. Eggs and young fish were also used to achieve a breeding population of sturgeon in Legend Lake, a 1304 acre lake in Menominee County. Sturgeon successfully spawned at the falls the following year. The tribe has proposed that fishways be constructed around both dams to allow spawning from populations in Lake Winnebago. However, due to concerns about aquatic invasive species and Viral hemorrhagic septicemia (VHS), a deadly fish disease, the proposal has not yet been implemented, and the capture and relocation program has continued. Zebra Mussels Zebra mussels (Dreissena polymorpha) are small, freshwater, bivalve shellfish native to the Caspian and Black Seas south of Russia and Ukraine. They can clog water intakes and pipes, encrust piers, boats and motors, and cut the feet of swimmers. Zebra mussels have been found in less than 5% of Wisconsin lakes predicted to be suitable for zebra mussels. However, they were detected in the Winnebago Pool including the Wolf River as early as 1999. Flora and Fauna Fishing There are many different species of fish in the river. In 2016, the Wisconsin state record Quillback was caught in the Wolf River. It was long and weighed . Sturgeon The Winnebago system, including Wolf and Fox Rivers and associated lakes,
