Hunters at Marsh and Lac qui Parle lakes in the Lac qui Parle Wildlife Management Area in west-central Minnesota can expect lower water and refreshed vegetation this waterfowl season.
The Minnesota Department of Natural Resources-managed Marsh Lake was drawn down by about 2 feet from its typical 4-foot maximum depth this spring and early summer. The lower levels were maintained through July, allowing regrowth of aquatic vegetation, which will also improve water quality.
In August, water levels were allowed to begin rising again, but staff plans to keep the water levels at their current level through the entirety of waterfowl hunting season, which starts with the early teal season Saturday, Sept. 5 through Wednesday, Sept. 9. The regular waterfowl season opener is Saturday, Sept. 26.
The connected Lac qui Parle Lake is managed by the Army Corps of Engineers. Water levels are affected by the drawdown at Marsh Lake and repair work underway at the emergency spillway by the dam between the two lakes.
“I’m hoping conditions will make for strong duck habitat and hunting this fall,” DNR Area Wildlife Supervisor Walt Gessler said. “But with low water levels and a changed environment, new and seasoned hunters should come prepared. Low water can increase the risk of capsizing on submerged obstacles for boats, plus drop-offs and deep mud for those wading. The changed vegetation may also impact concealment planning for hunters.”
The drawdown at Marsh Lake was successful in refreshing the vegetation. Cattail continues to be a strong presence on the lake, but is less dominant than before. Meanwhile, there is a diverse mix of emergent growth.
“The most abundant new vegetation emerging this year, in order of abundance, appear to be smartweed, chufa and bulrush,” Gessler said. “I was very surprised to see the large amount of these other species. I am especially impressed with how much bulrush is on the lake.”
The new vegetation is good for attracting waterfowl and for concealing hunters on the water. The changes are also expected to benefit fish populations when water levels return to normal.
Lac qui Parle birding tour
Lower water levels this fall will also result in enhanced habitat for shorebirds. There are numerous observation points around the two lakes, creating an ideal environment for bird watching.
Birders are encouraged to try out Lac qui Parle WMA’s newly installed self-guided birding tour. The tour includes 14 stops across the two lakes in the WMA, with each point including descriptions and a link to driving directions.
