Water Regulation and Zoning should remove the dam on Logan Creek to improve the water quality. It is included in NR 102 as an Outstanding Resource Water. The area is trapped heavily for muskrat, mink and beaver. The Swamp Creek system includes Outlet, Hemlock, Gliske, Logan and its branches, Rocky Siding and Hemlock creeks. These are high quality trout streams although the area is plagued with beaver.
Little information is known about the impacts of beaver activity on the water quality of the system.
Intensive beaver control measures are ongoing. Gliske Creek Gliske Creek is an excellent Class I trout stream. North Central District fish managers maintain a constant rehabilitation program for beaver control although management can be difficult with limited public access to the stream. There is some consideration for creating a fishery area and purchasing access easements. Logan Creek Logan Creek flows into Bishop Lake, which often winter-kills possibly as a result of low dissolved oxygen waters released from the dam on Logan Creek.
