Natural resource agencies will join together to research the deterioration of water quality in the Black River. The problem dates back to 1920 when a dam was built at the mouth of the Black River for use during log drives, Loman resident Jim Palm told the Koochiching County Board. After the last log drive in 1937, the dam was left to deteriorate. Thirty years later in 1967, Palm said he realized something needed to be done to protect the river. He began conversations with the U.S. Army Corps of Engineers to encourage removal of the dam. Army Corps staff said the agency couldn’t remove it because there is no proof of who constructed the dam, Palm said. Palm found a contract between his father and the International Lumber Company regarding the dam and two weeks later the Army Corps was visiting the Black River. A portion of the dam was removed in 1970 by a Boise Cascade crew, according to Palm. But the partial removal resulted in silt filling into the pilings left there and, as more silt fills in, water quality and water movement may have been impacted. The Minnesota Pollution Control Agency agrees with Palm and is supporting a team that would research the silt issue.
