Lake Level and Outlet


The current lake level for Prior Lake can be seen on the Prior Lake-Spring Lake Watershed District’s website.

There seems to be some confusion about the new, more efficient underground outlet of Prior Lake to Jeffers Pond. The Prior Lake controlled lake level for decades is that the outlet would be opened when the lake level reaches 902.5 ft. elevation. The new outlet box in Grainwood Bay is more efficient and is designed to not clog as easily as the old one. That is why the drainage area downstream had to be improved by making native plantings to prevent erosion with any increased flowage. However, the governing agencies did not lower or change the 902.5 ft. elevation figure that they use to open the outlet to allow water to flow out of Prior Lake. The current water elevation is 902.20 ft. and means the lake level would have to rise about four inches before water would flow into the outlet. To learn more and discuss Prior Lake’s invasive plants, zebra mussels, its impaired status, and other subjects, plan to attend the Prior Lake Association’s annual membership meeting on Thursday, October 28th at 6:30 pm in the lower level of the Prior Lake VFW. Social time is 6:30 to 7:30 with light snacks, and a short business meeting at 7:30 pm. In other lake news, the lake elevation was 902.20 as of Wednesday, Oct. 6th. The water clarity was 4 feet, and the surface water temperature was 61 degrees. Enjoy your lake, and take time to attend the Prior Lake Association’s annual meeting on Thursday, Oct 28th at the Prior Lake VFW at 6:30 pm.
