The MCWD controls the headwaters structure at , the outlet of Lake Minnetonka to Minnehaha Creek. And according to MCWD, the discharge at Lake Minnetonka’s Grays Bay Dam was reduced to 50 cubic feet per second earlier today, in order to build capacity in Minnehaha Creek for the rainfall we’re expecting.   

On June 20, the lake level of Lake Minnetonka (Lake Minnetonka's elevation above sea level), as measured at Minnetonka’s Grays Bay, was 929.65 feet.
