ST. PAUL, Minn. – The U.S. Army Corps of Engineers, St. Paul District, continues to monitor water levels at its Mississippi River Headwaters reservoirs. The water levels in the reservoirs, except for Pokegama Lake, are below the summer target level, which is the level maintained for water supply, environmental and recreational benefits. All reservoirs are releasing the minimum flow. The Corps urges boaters to go slow and use caution in lower-than-normal lakes levels.
