Wisconsin State Natural Areas Program Black Lake Bog (No. 196)


Overview

Location

Within the Douglas County Forest. Douglas County. T45N-R15W, Sections 8, 17, 18, 19, 20, 29, 30. 2,008 acres.

Description

Description

Located on end moraine, Black Lake Bog contains a vast, inaccessible, undisturbed wetland complex of bog lake, open bog, and northern wet forest, a community poorly represented in the younger drift, west zone. The open bog is dominated by leather-leaf with patches of bog-rosemary. Black spruce are scattered in the bog and are usually stunted but occasionally grow into a dense stand of full-sized trees. The bog and Black Lake form the headwaters of the Black River. Black Lake is entirely muck-bottomed and has a maximum depth of 4 feet, methyl purple alkalinity of 28 ppm, and a Secchi disk reading of 3 feet. Black River has a gradient of 22 feet/mile and methyl purple alkalinity of 41 ppm. The river below the outlet averages 2.5 cu. Ft./sec. Wildlife found on the tract include waterfowl, great blue heron, beaver, and short-eared owl which may nest in the bog. Gray wolves also use the area. Black Lake Bog is owned by Douglas County and was designated a State Natural Area in 1985. The portion of the bog in Minnesota is designated a Scientific and Natural Area.

Access

Driving directions

From Superior go south on Highway 35 about 17 miles, then west on Foxboro Chaffey Road 4.5 miles, then south on Thompson Road 2 miles. Continue south on Matlock Road 1.3 miles until it ends near the Black River. At this point an abandoned railroad bed crosses the river and a canoe can be launched. The natural area lies upstream. This huge wetland straddles the Wisconsin-Minnesota boundary and the western portion is designated a Minnesota Scientific and Natural Area.

Ownership

Black Lake Bog is owned by:

  • Douglas County

Maps

The DNR's state natural areas program is comprised of lands owned by the state, private conservation organizations, municipalities, other governmental agencies, educational institutions and private individuals. While the majority of SNAs are open to the public, access may vary according to individual ownership policies. Public use restrictions may apply due to public safety, or to protect endangered or threatened species or unique natural features. Lands may be temporarily closed due to specific management activities. Users are encouraged to contact the landowner for more specific details.

The data shown on these maps have been obtained from various sources, and are of varying age, reliability, and resolution. The data may contain errors or omissions and should not be interpreted as a legal representation of legal ownership boundaries.

Recreation

Very few State Natural Areas have public facilities, but nearly all are open for a variety of recreational activities as indicated below. Generally, there are no picnic areas, restrooms, or other developments. Parking lots or designated parking areas are noted on individual SNA pages and maps. Trails, if present, are typically undesignated footpaths. If a developed trail is present, it will normally be noted on the SNA map and/or under the "Access" tab. A compass and topographic map or a GPS unit are useful tools for exploring larger, isolated SNAs.

Non-DNR lands
