Water Levels: Lake Minnetonka and Gray's Bay Dam

Questions about water levels, canoeing, or the MCWD's operation of the Gray's Bay dam? Learn more about Gray's Bay Dam.

You can view real-time water level readings of Lake Minnetonka here and Minnehaha Creek here, as part of a partnership between MCWD and the U.S. Geological Survey. Please note, the USGS refers to creek flow as "discharge" on their site.

Ideal creek flows for paddling are between 75 and 150 cubic feet per second (cfs). We do not recommend paddling when the creek's flow is higher than 150 cfs. Conditions can change rapidly, especially after rainfall. We recommend using the real-time flow at Hiawatha Ave to gauge how fast the creek is flowing in the lower half of the creek, and the Gray's Bay Dam discharge to gauge how fast the creek is flowing in the upper half of the creek. Learn more about paddling the creek.
