Updated Lake Levels as of 6/20/19

According to Jerry Spetzman, Chisago Lakes  Lake Improvement District Administrator, here are the highlights of today’s (June 20, 2019) inspection:

Lofton Weir. According to the Operation and Maintenance plan both the high and low weir control gates are to be open when the water level at North Lindstrom Lake exceeds 899.2. The high weir was opened on April 19. At that time water levels were not high enough to flow over the weir. On May 9 the Low weir was opened and water is flowing through the weir into Green Lake. The weir will remain open until Chisago/North Lindstrom/South Lindstrom waterlevels are lowered to 898.7 at which time the weir will be closed.

North Lindstrom Lake. A water level gauge is located on North Lindstrom Lake. The water level elevation at this gauge today was 898.80 (per DNR gauge calibration). This elevation is a good representation of the water levels of Chisago/South Lindstrom/North Lindstrom Lakes. The Ordinary High Water level of these lakes is 900.2. The lakes are 1.4 feet below OHW.

Paradise Park Weir. This weir is a fixed cable concrete weir that drains Chisago Lake into Wallmark Lake under high water conditions. The weir has a permanent outlet elevation of 899.2. Today the water level is below the crest of the weir. Water is not flowing from Chisago Lake over the weir toward Wallmark Lake. The estimated water level elevation at this weir is 898.87.

Lake Ellen Weir. The weir is to be open during the open water season when Little Green Lake water levels exceed 891.0. The weir was initially opened on April 10. Water is flowing through the weir into Swamp Lake. Unless downstream issues arise, it is anticipated the weir will remain open until fall.

Little Green Lake. A water level gauge is located on Little Green Lake. The water level elevation at this gauge today was 891.64 (per DNR gauge calibration). This elevation is a good representation of the water levels of Green/Little Green/Ellen Lakes. The Ordinary High Water level of these lakes is 892.5. The lakes are 0.86 feet below OHW.

South Center Lake. A water level gauge is located on South Center Lake. The water level elevation was taken at this gauge Tuesday, June 17.  At that time the water level elevation was 898.97 (per DNR gauge calibration). This elevation is a good representation of the water levels of North and South Center Lakes. The Ordinary High Water Level of these lakes is 900.2. At the time of the readings the lakes were 1.23 feet below OHW.

LID staff are taking weekly lake level readings on other lakes in the Chisago Lakes area.  Lake level readings are published weekly in the Chisago County Press.

The Chisago Lakes Channel & Weir system is being actively managed according to the guidelines established in the 2016 Channel & Weir – Operations & Maintenance Plan. A copy of the plan can be found at:

Since early April, Lake Improvement District staff along with the LID engineer have been conducting weekly inspections of the channel & weir system. Inspection reports from previous years can be found at https://www.chisagocounty.us/321/Channel-Weir-Maintenance-Reports
