Lake Levels on Chisago, North/South Lindstrom Update

The Administrator for the Chisago Lakes Lake Improvement District, Jerry Spetzman sent an update on the Chisago, North and South Lindstrom Lake levels.

Here are the highlights of yesterday’s (May 9, 2019) inspection:

Lofton Weir.  The water level elevation at the Lofton weir was 899.23.  This elevation is a good representation of the water levels of Chisago/South Lindstrom/North Lindstrom Lakes.  The Ordinary High Water (OHW) level of these lakes is 900.2.  The lakes are approximately one foot below OHW.  According to the Operation and Maintenance plan both the high and low weir control gates are to be open when the water level 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.  Today, the Low weir was opened and water is flowing through the weir into Green Lake.  The weir will remain open until water levels are lowered to 898.7 at which time the weir will be closed.

Paradise Park Weir.   This weir is a fixed cable concrete weir.  The weir has a permanent outlet elevation of 899.2.  Today water is starting to trickle from Chisago Lake over the weir toward Wallmark Lake.

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:—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.  Attached is a copy of the April 25, 2019 Spring Channel and Outlet Structure Inspection report which summarizes activities in April.  Inspection reports from previous years can be found at
