Green Lake Weed Management:
We must realize native weeds have a important place in our Green Lake. Weeds provide fish habitat. Weeds also help reduce wave height/strength hence shoreline erosion damage from our sometimes crazy winds and large boat wakes. And can't ignore the stirred up lake sediment containing nutrients that feed the weeds!
Weed management and lake water quality is a delicate balance. Our Green Lake has plenty of weeds!
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.

2023 Green Lake AIS Curly Pond Leaf Control Treatment- COMPLETED MAY 15th
2023 CLP Treatment Report
2023 DNR Permit
2023 CLP Treatment Invoice
Green Lake was recently issued permission to use CPL invasive species herbicide Diquate 1.5 gallons/acre for 50.5 acres. What does this mean? Diquate is far more effective and cost much less than treatments we've been allowed to use in the past. It's able to kill the Curly Pond Leaf, Eurasian Watermilfoil,, and other weed infestations for a 3 for 1 effect with less chemicals going in to the lake.
GLID is using AIS treatment Best Practices to retreat same areas to reduce the CPL Turion bank buildup. Could take more than 5 years to combat root regrowth! 2023 note: DNR approved GLID's same best practices AIS treatment.
For detail CLP study, click here> Evaluation of lake wide, early season herbicide treatments for controlling invasive curlyleaf pondweed (Potamogeton crispus) in Minnesota lakes net net: "Although CLP eradication may not be feasible, our results indicated that herbicide treatments can effectively reduce severe infestations of curlyleaf" Use with permission from James Johnson.
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.

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.
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
CLICK HERE FOR COMPLETE DNR Weed Control details :
Removing weeds from your lake is always the best option to reduce nutrient budget loading that causes more weeds to grow.
NOTE>>> Green Lake has a FREE COMPOST PILE (WEEDS ONLY PLEASE) area by Wyanett Township Maint Building at 34591 NACRE Street NW

Some lake owners are using an ECO Weed Harvester (not a cutter) that 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!! The more Lake owners remove weeds from lake, less nutrients remain to grow more weeds.
1 pound of Phosphorus can produce 500 pounds of algae in one year!!!!

GREEN LAKE with SWCD PARTNERSHIP EARNS MPCA GRANT TO IMPROVE LAKE
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
2023 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
2020 Sector 319 Grant Green Lake Initial Work Plan Only.pdf GLID-SWCD MOU Green Lake Restoration Program
Green Lake 2022 TP+Chlorophyll + Secchi Disk Readings Combined Water Quality data analysis hotlink
NET NET:::
>"Over the long term the Phosphorus trend is slowly increasing and above the threshold. "
>"Over the long term the Chlorophyll’s trend is stable and above the threshold. However, the short term trend for chlorophyll-a is declining"
"Over the long term the Secchi water clarity trend is stable and above the threshold."
2022 Secchi water clarity average range was 3.6 ft - 5.6 ft
" So, the short story is: I see some positive trends in the long term data for Green Lake. However, we need to act now to build up some more momentum and flip all of the trends to improvement!" - SWCD
Green Lake Volunteers, Pam with Corey Mortenson family along with Marissa & Alex Dahlin helped David Dancik collect water samples for lab analysis and 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 has been monitored for secchi from 1988‐2022, Click here for Green Lake Secchi History. More planned for 2022-2024
2021 Green Lake Sacchi Average was 5.26 feet 2022 Secchi water clarity average range was 3.6 ft - 5.6 ft
30 year average of 5.9 feet with unknown degrees of error
Green Lake has met the 1.4-meter or 4.6 ft Secchi clarity depth lake standard in about 70% of the past 30 years years measured .
Most days GOOD Clarity... others NOT!
example: Secchi set: 8 by Mel and Clint Date: 7/18/21 Time: 3:25pm Lake: Green Lake
Depth at Sampling Site: 31ft Secchi Disk Clarity Depth: 6ft 6in Physical Appearance: Clear (in middle, edges of lake have floating algae) Recreational Suitability: Good (in middle) Weather/Wind: Sunny / 0-5 mph Water Temp: 81 degrees
Most recent June 22, 2022 - Clarity at 6ft 10 inches! Per DNR: Lake Trend: Improving Lake Name Green; Lake ID 30-0136-00

Green Lake Is Nutrient Rich With Phosphorus, Nitrogen, and Potassium !
What Does That Mean? Means more weed growth!
INCREASED PHOSPHORUS = INCREASED CHLOROPHYLL = DECREASED WATER CLARITY.

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
> CD3 System boat weed-cleaning system is now installed at Spec Lake that has the dreaded Zebra Mussels! 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"
