Corps of Engineers to increase flow from Lac Qui Parle Dam

Published Oct. 3, 2017

ST. PAUL, Minn. – The U.S. Army Corps of Engineers, St. Paul District, plans to increase outflow from the Lac Qui Parle Dam, near Watson, Minnesota, starting today.

With the dam basin filling up after a very wet fall – more than five inches of rain in September and an additional two inches already in October – the Corps increased outflow to 2,500 cubic feet per second, or cfs, late last month and will continue to do so in order to keep the pool below the emergency spillway.

The plan is to increase the outflow to 3,000 cfs today, 3,500 cfs tomorrow and 4,000 cfs Thursday. Each day the Corps will re-evaluate basin conditions (including adjusting for any additional rainfall) before increasing outflow.

The pool is currently at an elevation near 937 feet NGVD29, with roughly four feet of storage in the pool.

The nearly 600 U.S. Army Corps of Engineers, St. Paul District, employees working at more than 40 sites in five upper-Midwest states serve the American public in the areas of environmental enhancement, navigation, flood damage reduction, water and wetlands regulation, recreation sites and disaster response. Through the St. Paul District Fiscal Year 2016 $78 million budget, nearly 1,250 non-Corps jobs were added to the regional economy as well as $120 million to the national economy.
