Our mission is to serve as stewards of our lake community, to protect, preserve, and improve the quality of Green Lake. We will work cooperatively with the County and State Agencies to continuously refine our goals and develop annual work plans to meet these goals. We will oversee funds collected and expended to accomplish this mission. “Unless someone like you cares a whole awful lot, Nothing is going to get better. It’s not.” Dr. Seuss
Purpose
Green Lake Improvement District (GLID) was incorporated as a non‐profit organization on July 1, 2001. It functions with a nine‐member elected board and exists as a local government body under Isanti County. Information is disseminated to lake property owners and the general public via mailings and through the web site: http://www.greenlakemnid.com
The GLID was initially formed to take over the ownership and operation of a water control structure at the confluence of Green Lake Brook and the Rum River. This mission has since been expanded to include the protection and improvement of Green Lake and its watershed.
A BRIEF SUMMARY OF GREEN LAKE: Somethings You Might Want to Know about Green Lake LAKE DESCRIPTION Green Lake is in the southern portion of the Rum River watershed with Mille Lacs Lake being the largest lake at the head of the watershed. Green Lake itself does not receive direct inflow from the Rum River, and as such, operates much like a head water lake with few inputs. Green Lake does, however, contribute to the Rum River and downstream receiving waters from it. The lake has a relatively small contributing lakeshed (15,875 acres, which is less than 2% of the 1,584 square mile area of the watershed) dominated by agricultural uses . The drainage basin: lake area (DB:LA) size ratio can vary from near 0 to over 1,000 and Green Lake’s is approximately 20, which is small. Lakes with small DB:LA ratios tend to be deeper with less external nutrient inflow than lakes with higher values. Small DB:LA lakes tend to have water budgets dominated by groundwater flow and long nutrient retention times. It is also notable that Green Lake has legacy sediments from Glacial Lake Grantsburg (Fig. 3). Glacial lake sediments are naturally high in clay and nutrient contents even before accounting for influx from agriculture lands. Green Lake is the largest and deepest lake in Isanti County and also has a large fetch, which is the distance wind blows across the lake and correlates to annual wave energy (Table 1). Lakes with high wind energy have high concentrations of suspended sediments due to bottom disturbance in shallow areas. Reference: Green Lake Status Report 2018 by Limnopro Aquatic Science
Physical Characteristics and location of Green Lake Green Lake is located in the west‐central area of Isanti County and lies within Wyanett Township. The total drainage area of Green Lake is 15,875 acres. Green Lake is an oval lake totaling almost 833 acres. The shoreline extends 4.4 miles. This amounts to 189 acres of water per mile of shoreline. The predominant land uses within the lakeshed are cultivated crops, deciduous forest and pasture or hay. There are 45 separate emergent, herbaceous and woody wetlands. Together, these total almost thirteen percent of the drainage area, not including the lake itself. The main inlets are Wyanett Creek, North Brook Creek, and three unnamed creeks.
