In March 2005 the Lone Lake Association was invited to participate in the Initiative Foundation’s Healthy Lakes and Rivers Partnership program along with seven other Lake Associations in Itasca and Aitkin Counties. Under the coordination of Art Norton (Itasca County Soil & Water Conservation District) and Steven Hughes (Aitkin County Soil and Water Conservation District) representatives of each group attended two days of training on strategic planning, communication, and nonprofit group leadership.
Every 5 years the LLPOA board of directors reviews and updates the Lone Lake Management plan. The most current version is available for download. If you have any questions about the plan, don’t hesitate to contact us. Email us at firstname.lastname@example.org.

How clear is Lone Lake?
For clarity, Lone Lake is ranked in the top 10% of Minnesota lakes. Water transparency is an excellent indicator of water quality.
How is water clarity measured?
An black and white disc called a Secchi disc is lowered by hand into the water to the depth at which it vanishes from sight. The distance from the top of the water to the vanishing point is then recorded. The clearer the water, the greater the distance. A participant of the MPCA Citizen Monitoring Program, Dave Scott, Lone Lake resident, conducts this measurement at the same point on the lake every week during the ice-out season.
What is Lone Lake’s clarity measure?
As of June 20, 2014 the Secchi disc reading was 32 ft. It was 27.5 ft on May 28, 2014. These readings are on the high end of average for the lake. To see the trend starting from 1974, go to the MPCA (Minnesota Pollution Control Agency) website and click on the transparency trend tab.
What determines the water level?
Several factors: 1) precipitation versus evaporation. Aitkin County on average gets slightly more precipitation per year than what evaporates. 2) Inflow and outflow of water. Lone Lake, nestled in high ground compared to the surrounding lakes and streams, has a small watershed. Our inflow is primarily from local ditches and lawn run-off. We have a 15” in diameter culvert at the northwest end of the lake, taking water out toward Ripple Lake. The elevation at which water leaves Lone Lake through the culvert is at 1,263.43 ft. 3) other natural elements, such as a beaver dam, could affect the lake level, too.
What does Ordinary High Water Level (OHWL) mean and what is Lone Lake’s?
Under Minnesota Statutes 103G. 005, Subd. 14, “Ordinary high water level” means the “boundary of water basins, watercourses, public waters and public waters wetlands, and: 1) the ordinary high water level is an elevation delineating the highest water level that has been maintained for a sufficient period of time to leave evidence upon the landscape, commonly the point where the natural vegetation changes from predominantly aquatic to predominantly terrestrial.”
