Bashaw Brook, Sand Creek, South and North Forks of the Clam River are a part of the Upper Clam River Watershed. They are to the west of the Shell Lake-Yellow River watershed. Within these watersheds are 56 lakes and 14 streams as well as groundwater.


  • The lower reaches of the Yellow River and Yellow Lake are home to 1 of 6 naturally reproducing lake sturgeon populations in the nation that have over 1,000 sturgeon. To say we have a unique resource is an understatement!
  • Shell Lake is listed as an Outstanding Water Resource by WI DNR, has naturally reproducing walleye, and is one of the best smallmouth bass lakes in Washburn County.
  • Several lakes in the watershed have healthy, abundant fish populations, including musky, largemouth bass, and panfish.
  • Benoit Lake has a small cisco population. Ciscos require cold water with good water quality to survive.
  • Several trout streams are present in the watershed, which depend on cold groundwater.
  • The Upper Clam River Watershed has high quality trout streams which are some of the best in the area.
