The Black River winds northward through the central part of Koochiching County, one of the many waterways that shape this corner of northern Minnesota.
The Black River is part of the county’s network of rivers that drain northward toward the Rainy River system. Like its neighbors, it carries water steadily toward the border country to the north.
This is a quiet, largely undeveloped river. It runs through country that has seen little development, keeping a low profile among the better-known lakes and rivers of the region.
More detail on access and recreation will be added here as it becomes available.

Rules for this place
The border waters section of the Minnesota fishing regulations covers only the lower reach of the Black River, and the water above that point is not in it. Minnesota’s invasive species law rides home with the trailer: pull the drain plug, drain the water, and leave plants and prohibited species at the access. Part of the Black River is on the DNR’s infested waters list for spiny waterflea, which adds bait and water-transport rules for anyone leaving it; the list gives the exact reach.
