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:https://www.chisagocounty.us/DocumentCenter/View/9489/2016-LID-Channel-and-Weir—Operations-and-Maintenance-Plan-updated-June-27th-2017
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
Here are the highlights of today’s (June 27, 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. The weir is to remain open until Chisago/North Lindstrom/South Lindstrom water levels are lowered to 898.7. Today, the water level of Chisago/North Lindstrom/South Lindstrom is 898.66. The high weir was closed today.
North Lindstrom Lake. A water level gauge is located on North Lindstrom Lake. The water level elevation at this gauge today was 898.66 (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 1.54 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.
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 891.66 (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 0.84 feet below OHW.
South Center Lake. A water level gauge is located on South Center Lake. The water level elevation taken at this gauge today is 898.70 (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. The lakes are 1.5 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.
