capstone project to analyze lake system resiliency

October 27, 2017

Saint Paul Regional Water Services, the drinking water utility for Saint Paul, MN, pumps water from the Mississippi River to the city’s drinking-water treatment plant through a chain of lakes connected by conduits and canals. This large inflow of water, combined with precipitation, causes lake level changes that can result in bank instability, erosion, and reduced water quality.

Pleasant Lake in North Oaks is one of the lakes subject to significant fluctuations in water levels that could have adverse effects. Now a University of Minnesota–Twin Cities engineering capstone project will analyze differences between fluctuations in the lake related to Mississippi River inputs and natural fluctuations that would exist if there was no pumping to provide management recommendations to increase the lake’s resiliency. Read more about the project—proposed by Barr’s Michelle Stockness and Dr. Omid Mohsenihere on page six. The students are being mentored by Omid for a stakeholder group that includes Vadnais Lake Area Water Management Organization (VLAWMO), St. Paul Regional Water Service (SPRWS), North Oaks Home Owners Association (NOHOA), City of North Oaks, and North Oaks Company.
