There is an old Facebook page out there, but the Green Lake board does not have access to this page, so we decided it would be easiest to create a new one https://www.facebook.com/glidisanticomn Please give it a 'LIKE' please.
Announcement: YEA! Green Lake Volunteers, Pam with Corey Mortenson family along with Marissa & Alex Dahlin will be helping David Dancik with water samples for lab analysis and continued water clarity Secchi readings in 2022 as part of GLID Lake Improvement Plan activities. Info: Water clarity is measured using a Secchi disk, a plate-sized disk with black and white sections that is lowered into the water until it can no longer be seen. The deeper the Secchi disk is lowered and still is visible, the clearer the water. As a general rule, the maximum depth to which plants grow is twice the midsummer Secchi depth.

Green Lake Weed Management:
Weed management requires knowledge, time, patience and money. There is no magic bullet that will eliminate excess weeds without continued effort and without side affects.... A lake, after all, is not a swimming pool but a dynamic, complex system and expectations should be realistic.
--- reference Aquatic Weeds: Nuisance and Necessity Cayuga Lake Watershed Network 2009 Study hotlink
Green Lake was invaded by Aquatic Invasive Species (AIS) that are non-native plants, fish, invertebrates and microbes. These species tend to spread rapidly in new areas, out-compete native resident species, and cause ecological or economic harm including possible impacts to human and pet health.
Management of invasive aquatic plants that involves either mechanical removal of plants or application of herbicides to public waters requires a permit from the DNR. Permits may be issued to property owners, lake organizations and local governments.
Fact: The spread of AIS follows the highways... hitching rides on boats & trailers.
2022 AIS Boat Inspections :– GLID has Inspectors at Green Lake public access starting May 18 until Sept 5
Tuesdays 3-8p Wednesdays 2-8p Thursdays 2-8p Fridays 10-7 Saturdays 10-7 Sundays 10-7
GLID Requested 44 hrs X 20 weeks of funding from Isanti Zoning.. 2021 found .4% violators. Stopped an Zebra Mussel entry!
Boat Inspections raise awareness! Hopefully Prevent new Zebra Mussel invasion.. along with Starry Wart

WHAT CAN YOU DO TO HELP HALT SPREAD OF AQUATIC INVASIVE SPECIES (AIS)? hotlink
Help Protect Minnesota Waters: Know the Law (HOTLINK). You may not ... transport watercraft without removing the drain plug • arrive at a lake access with drain plug in place • transport aquatic plants, zebra mussels, or other prohibited invasive species such as faucet snails, ruffe, and round goby • launch a watercraft with prohibited species attached • transport water from Minnesota lakes or rivers; or release bait into water
2021 Green Lake AIS Curly Pond Leaf Control Treatment- DONE MAY 5TH
Green Lake was recently issued permission to use CPL invasive species herbicide Diquate for 50.5 acres. What does this mean? Diquate is far more effective than treatments we've been allowed to use in the past. It's able to kill the Curly Pond Leaf and Eurasian Watermilfoil for a 2 for 1 effect with less chemicals going in to the lake.
GLID is using AIS treatment Best Practices to retreat same areas as 2020 to reduce the CPL Turion bank buildup. Could take more than 5 years to combat root regrowth! 2022 note: DNR indicating approval of GLID's same best practices AIS treatment.
Question from Lake Owners; Why doesn't GLID treat in front of my property>
Answer::: With limited approved acres, GLID/DNR treats areas of highest density per AIS survey... not all areas of lake are treated. However, every year, AIS weed congestion analysis is done and decisions made for best ROI following recommended best practices.
It is a delicate balance to reduce AIS infestations for lake enjoyment of swimming, boating, fishing.
Green Lake is prohibited from touching the native protected Coontail weed infestations.

Post Treatment Results Summary: "As far as invasives go, the Green lake looks great. ,,,found one lone plant of Curlyleaf Pondweed, and that was it."
"The May 6th treatment used diquat herbicide, which can have dual impact on both Curlyleaf Pondweed and Eurasian Watermilfoil. For the second consecutive year, we did not find any Eurasian Watermilfoil in Green Lake.
While invasive plants were well under control, native plants were widely abundant in the shallow nearshore waters. Clasping Leaf Pondweed was observed flowering at the surface in many areas and Coontail was also widely abundant in several areas, with filamentous algae growing on top of it."

> Webinar: Septic Secrets - Protect Your Investment and Protect the Lake with Good Septic System Maintenance
Locating and replacing leaky septic systems near the lake is important. Leaky septic systems
can be a significant source of phosphorus and coliform to the lake, depending upon the severity of the leak, proximity to the lake, and soil characteristics between the leaky septic system and the lake.
On April 17th, Minnesota Lakes and Rivers Org along with University of MN Water Resources and Minnesota Health Dept provided a webinar about septic best practices and what a good and bad septic can affect. Grab a beverage and watch the video at the link below! Watch here! Short brochure version: Webinar: Septic Secrets Slides
AND from Upper Hay Lake Association wonderful information... SEPTIC OVERVIEW AND MAINT
> Water Pollution: How Humans Impact the Water Cycle and Water Pollution's Impact on Our Green Lake- hotlink
When substances contaminate water sources and make them unusable for drinking, cleaning, and swimming, the sources are polluted. Water pollutants include trash, chemicals, parasites, and bacteria. Because of the water cycle, all types of pollution eventually arrive in the water supply, where they act as poisons or cause diseases like cholera. Toxic chemicals may also impact animals and plants, which can then affect humans when the animals or plants enter the food supply.
Types of Water Pollutants: Water pollutants may originate from direct or indirect sources. Direct pollution includes output from refineries, factories, and waste treatment plants. Indirect pollution includes any contaminants that enter the water supply from the soil, groundwater, or atmosphere. Soil and groundwater contamination happens due to faulty septic systems, agricultural practices and industrial waste that's not disposed of properly.
> CD3 Systems boat weed-cleaning system now installed at Spec Lake! CD3's are a waterless, free, user-operated cleaning equipment that includes wet/dry vacuum, blower system, tethered hand tools and lights. Watch Why and How to use CD3 Video hotlink.
From Darrick of Isanti Zoning/AIS Mgmt: " Those that do lake hop between Spectacle and Green, should powerwash them at home and/or remember to dry their boats 5-7 days"

Minnesota Pollution Control Agency with Isanti County SWCD Secured Green Lake Section 319 Small Watersheds Focus Program Nine Element Plan Grant Learn more about our SWCD partner hotlink
2021 YE Summary Hotlink of Green Lake Section 319 Watershed Program prepared by SWCD
• The Green Lake Section 319 Small Watershed Focus Program Nine Element (NKE) Plan was developed by compiling and synthesizing information from previous studies and planning documents conducted in the watershed. Green Lake Studies and Reports - From MPCA and EPA, This plan is federally approved. The work plan leverages the $284,000 Grant
• Addresses water quality, mercury content, AIS, TP Loading, and nutrient Reduction in Watershed areas.
Goal is getting Green Lake off MN Impaired Lake list in 10 years. by reducing TP loading by 2,142 lbs/year every year.
"Green Lake is still considered impaired since TP and chlorophyll-a do concentrations do not currently meet State standards.
TP concentrations for Green Lake have averaged 61 µg/L over the most recent 10-year period, which is above the 40 µg/L standard for deep lakes in the North Central Hardwood Forest (NCHF) Ecoregion. Planktonic algae, which is measured by chlorophyll-a (chl-a), has averaged 25 µg/L which is above the 14 µg/L standard for deep lakes. Secchi depth, a measure of water clarity, is relatively good in Green Lake and has met the 1.4-meter Secchi depth standard in five of the seven years measured since 2009. Although Secchi depth has generally met State water quality standards over the past 10 years." reference Green Lake Diagnostics Study

Weed Control Around Your Docks
Green Lake home owners can help reduce nutrient loading in the lake by removing weeds from the lake.
Also, using lake shoreline best management practices reduces nutrient runoff into the lake.
CLICK HERE FOR COMPLETE DNR details : Under Minnesota law, aquatic plants growing in public waters are the property of the state. Because of their value to the lake ecosystem, they may not be destroyed or transplanted unless authorized by the Commissioner of the Department of Natural Resources as stipulated in the Aquatic Plant Management Rules
Net net: If you are a lakeshore property owner who wants to maintain a swimming or boat-docking area, you may cut or pull submerged vegetation without a DNR permit under certain conditions:
• First, the area to be cleared must be no larger than 2,500 square feet.
• Second, the cleared area must not extend more than 50 feet along the shoreline
NOTE>>> Green Lake has a FREE COMPOST PILE area by the Wyanett Township Grader Shed! YUP, FREE! WEEDS ONLY PLEASE
HIRING LAKE WEED TREATMENT
Removing or killing AIS weeds from lake reduces weed and algae growth!
Companies and Local Helper that are available to help with weeds and muck around your dock.
OR learn to DIY chemical treatment approach and restrictions with DNR Permits.
An example is rake out your weeds OR hire help like:
> Isaac and Levi Thompson, Local Teenagers to help remove lake weeds or lawn care! Call or Text their Mom, Leah at 612-812-3042
> YourLake APM, (612) 454-0357 that is non-chemical simple and safe weed removal. They use scuba gear to go under the surface to pull your unwanted lake weeds by hand, by the root. Removing or killing the weed's roots prohibit regrowth.
Think about signing up your dock area for herbicide weed management with The Lake Restoration Company or Others

Some lake owners are using a ECO Weed Harvester (not a cutter) that also pulls weeds up by the roots to be collected in a bin, unloaded into a trailer, and hauled into the Wyanett Township/GLID FREE weed compost pile located by Grader shed.
THE MORE YOU KNOW:> One year, 8 tons of weeds were harvested, removing almost 160 pounds equivalent of Nitrogen, Phosphorus, Potassium.!
Research and Stearns Laboratory testing showed for that one ton of Green Lake weeds contain 9.36 lbs of Nitrogen(N) .
4.7lbs Phosphorus (P). and 5.63lbs of Potassium (K) fertilizer for lake weeds!! Lake owners probably remove a ton from their shore!
Removing weeds from your lake is always the best option to reduce nutrient budget loading that causes more weeds to grow.
Especially knowing that 1 pound of Phosphorus can produce 500 pounds of algae in one year!!!!
Also, using lake shoreline best management practices reduces nutrient runoff into the lake.
CLICK HERE FOR COMPLETE DNR details : Under Minnesota law, aquatic plants growing in public waters are the property of the state. Because of their value to the lake ecosystem, they may not be destroyed or transplanted unless authorized by the Commissioner of the Department of Natural Resources as stipulated in the Aquatic Plant Management Rules
Net net: If you are a lakeshore property owner who wants to maintain a swimming or boat-docking area, you may cut or pull submerged vegetation without a DNR permit under certain conditions:
• First, the area to be cleared must be no larger than 2,500 square feet.
• Second, the cleared area must not extend more than 50 feet along the shoreline
