Lac qui Parle-Yellow Bank
The Lac qui Parle – Yellow Bank One Watershed, One Plan (1W1P) planning area is located along the South Dakota border in west central Minnesota. The 622,856 acre watersheds are comprised of portions of Lac qui Parle, Yellow Medicine and Lincoln Counties. The Yellow Bank and Lac qui Parle River watersheds extend from originations in South Dakota and outlet to the Minnesota River, which traverses along the northern edge of the planning area. The Coteau Des Prairies, a terminal moraine formed from the most recent glaciation, travels in a southeasterly direction and intersects the southwest portion of the planning area. Topographic relief from the Coteau Des Prairies influences the general northeasterly trending waterflow and creates tremendous diversity in the planning area. Landscape along the Coteau Des Prairies is a mixture of agricultural and pasture land with intricate topography, whereas the northeast portion of the planning area experiences little elevation variation and has been heavily altered for agricultural production.
