The new update from Thursday, March 21 is that the Minneapolis Park and Recreation Board (MPRB) opened the Nokomis weir and Minnehaha Creek Watershed District (MCWD) opened the Gray’s Bay Dam today. Both the weir and dam were opened after close consultation with Minnehaha Creek communities and the MPRB. The decision to open the dam is based on MCWD stream monitoring data, which shows the creeks draining into Lake Minnetonka are collectively flowing at approximately 150 cubic feet per second (cfs), which helps explain the rapid rise in Lake Minnetonka’s water level. MCWD has chosen to release 50 cfs out of the dam in an effort to help mitigate some of the water coming into Lake Minnetonka but also to moderate the flow into Minnehaha Creek in an effort to not cause flooding along the creek. MCWD is trying to balance the water budget across our entire 178 square miles and is working hard to reduce and prevent flooding. The MCWD staff have committed to keep a close eye on water levels and to continue to coordinate with cities around the lake and creek.
