Lower Prior Lake was monitored by the Metropolitan Council’s CAMP Volunteer Monitoring program from 1998 through 2002. After re-gaining volunteer support, it was re-added to this program in 2013. Visit our Lake Monitoring page to learn about the CAMP program.

Connectivity to other waterbodies: Water flows into Lower Prior from Upper Prior. The lake level is controlled by the outlet structure which feeds the Prior Lake Outlet Channel (PLOC).

All lake level data below are approximate and preliminary – NOT to be used for legal purposes. Sudden drops or spikes are often due to calibration, which are manual adjustments to correct the lake level value. Please contact the PLSLWD office for official readings.
Note: graphs will not draw properly with Internet Explorer 9 or older browsers. Newer versions of Internet Explorer, Firefox, Chrome, or Safari browsers will work properly.
Given the significant amount of precipitation in the watershed, the PLSLWD asked for and received permission from the DNR to open the low-flow gate. The low-flow gate was opened on 8/18/16 and was closed on 9/12/16 as the lake level had dropped to 902.50′.
