Aquatic Invasive Species (AIS) is a threat to all MN Waterways.
Invasive species (IS) are species that are not native to Minnesota and cause economic or environmental harm or harm to human health.
Minnesota's natural resources are threatened by a number of invasive species such as zebra mussels, Eurasian watermilfoil, common buckthorn, and emerald ash borer. Invasive species can occur on land or in the water.
It's important that we all do our best to help protect our waterways for today and the future.
** If you suspect you have found Starry Stonwort or any other invasive species, note the exact location, don't disturb the area, take a photo or keep the specimen and contact the DNR & CLPO. Early detection is key!!!
2018 Stearns County AIS Ramp Inspections:
Stearns County has approved the CLPO proposal for Ramp Inspection Funding for the 2018 season.
A total amount of $19,120.00 has been approved, which should fund 1,158 hours of inspection. This is the full amount in which we applied for. We do have the option to purchase additional hours of inspection in the event we obtain any grant money from Wright County.
The current funding covers weekend inspection (Saturday and Sunday) starting in May and carrying thru to Mid October for both the ramps at Bobs Bay and the Black Pool. Additional inspection days will be covered on the Fishing Opener and Holiday weekends.
These funds are from the State of Minnesota AIS Prevention Aid.
Steve McComas did his final 2018 SS inspections in the last week of Oct. He surveyed the DNR landings, the Waterfront/BJ area, Clearwater forest landing, and the private landing on the east end of the lake. The result - no SS detected. The survey included work by Steve's diving as well as rake surveys.
2017 Aquatic Plant Survey: A summer aquatic plant point-intercept survey has been conducted on Clearwater Lake in July 2017, prior to Eurasian watermilfoil treatments that may occur. The survey followed the MN DNR protocol for point-intercept surveys. Sample points were generated in GIS by creating a grid across the lake with 100 meter spacing between points. Bathymetric contours were then uploaded from the Minnesota Geospatial Commons, and several points that were clearly greater than 20 feet deep were deleted. These contour maps are not always accurate, so several points were left in the survey that may be deeper than 20 ft. A total of 959 sample points were created, and it is expected a number of these points will be deeper than the maximum depth of aquatic vegetation growth, and several may be inaccessible. During the survey, we will navigate our boat to each sample point and toss a double headed rake out 2 to 3 meters, and retrieve. Each species found on the rake will be recorded on a spreadsheet, and given an estimated density rating. Additionally, we will visually look for Eurasian watermilfoil in between the sample points, and will record locations if it was observed. A full report will be sent to the CLPO within one month of the survey. The report will include the following information: Assessment of the aquatic plant community in Clearwater Lake; and include data, statistics and maps showing the distribution of all aquatic plants, frequency of occurrence of each species, percent littoral zone vegetated, species richness and other statistics that allow further analysis of the aquatic plant community. A status report of Eurasian Watermilfoil, photo guide to aquatic plants in Clearwater Lake, and an excel spreadsheet with raw data.
