Attendees: Bruce Meyer, Connie Mayfield, Jason Houle, Bob Milam, Lori Reichert and guest: Mike O’Connell of Lake Management
Little Green Milfoil and Curly Leaf Treatments – Mike O’Connell of Lake Management, Inc. which currently does some portions of AIS treatment on Green.
- To get a better idea of what Lake Management could do for the Milfoil and Curly Leaf problems in Little Green, Bob Milam invited Mike O’Connell to join us to speak on using a Fluoridone treatment rather than the typical yearly treatments.
- Fluoridone can clear a lake of the harmful Aquatic Invasive Species (AIS) of Eurasian Milfoil and Curly Leaf, without harming the native aquatic species, and last for a longer period of time than our usual yearly treatments.
- EXPECTED DURATION of Treatment: Could be ten plus years on Eurasion Milfoil. Curly Leaf, after 10 years should still be 90-95% gone but even so, we might have to hit growth of curly leaf during that10-year timeframe but just in small amounts if caught early – so the same surveys would still have to be done on the lake to detect any invasive species cropping up. The treatment does NOT eradicate either invasive – they can still come in on boats or in the overflow into Green.
- Lake Management has had success on these comparable lakes: Clear Lake in Forest Lake (Bob Milam reports his friends on the lake are happy with it), Lake Josephine in Roseville and Schmidt Lake near Plymouth.
- MEASURMENTS OF LITTLE GREEN: (Important as to cost and timing.)
Per the DNR Website: Little Green’s shore length is approximately 2.5 miles, and it shows between 5 and 10 feet deep.
Median ice out date: April 11
Earliest ice out date: March 22, 2000
Latest ice out date: May 1, 2018
Per Mike: Little Green has an average depth of 8 feet and is 223 acres. NOTE: the product does not go below thermoclines.
- Expect between $30-40,000 total; probably $36,000 (this is different from the $25,000 we thought at our July meeting which Jason used for his first cost/benefit analysis).
- This covers all Lake Management testing costs, an expected initial treatment plus three more “bumps” of treatment during the year. The bumps are required in a non-contained lake. We will only be charged for the actual treatments. Fluoridone costs $2,800/gallon. The DNR limits its use to 4 parts/billion gallons of water. It disperses widely throughout the lake.
- CONCERNS from our last meeting answered:
- It is expected that non-invasive weeds will fill in where the invasive species had been, but it would be slow growth and they wouldn’t make the canopy that blocks light and effects the health of the water and fish.
- Doing the treatment in a time where water levels are lower to reduce flow in and out of Little Green might be better, however; per Mike, other treated lakes that had some flow were fine. Bruce is believing the lakes have got to be heading to lower after a couple years in a row of high levels in any case.
- Fluoridone has been in use since 1986; Sepro Sonar was the first company to use it.
- After treatment there are NO RESTRICTIONS on swimming, fishing, nor irrigation.
- REQUIREMENTS / TIMELINE:
- We must know the DNR will approve a permit to use Fluoridone on Little Green.
- We must have a Point Intercept study done on the lake. This entails getting GPS coordinates of all Eurasian Milfoil and Curly Leaf in all of Little Green. The Curly Leaf shows up more in later spring and it would be best to wait for that to get a clear picture of where it’s located (before the first annual spraying for it). This baseline will be used to verify that the Milfoil and Curly Leaf are gone after treatment.
- Per Mike, it is best to apply Fluoridone as soon after ice out as possible (median date April 11) to get the curly leaf and turions treated. Mid-April or earlier is best; although Lake Management has applied it in mid-May and it worked. It is not temperature dependent.
- Based on all these requirements, the timeline will probably be early spring of 2022 if the Board votes it in after all the Action Items below are completed.
- ACTION ITEMS:
- Jason will do another cost/benefit using the probable $36,000 for clearing the milfoil and curly leaf weeds in all of Little Green expected to last about 10 years vs. the yearly amount for small portions of the lake.
- Bob will talk to Chris Jurick (sp?) to get permission to use Fluoridone in Little Green Lake. She reports to Wendy Kohl who, per Mike, is pro Fluoridone use.
- Bob will contact a company to get the Point Intercept testing done (this test is good for two years). Some testing companies are: Blue Water, Barr, Dragon Fly, Fresh Water Scientific and others.
- Based on responses and timing on the above action items, the Board will decide if/when to apply the treatment to Little Green.
Public Dock / Chisago City Entry on Stinson – Lori
- UPDATE as of 9/15/2020, John Pechman called stating the city had the money for extending the sidewalk from the current one, through the arch, and then down to the city dock but they are having a difficult time getting a company that can do the job soon.
- Lori sent an email to Casey Theil and John Pechman. John was asked to send a plot plan to Casey so she can develop the plan. Casey was asked to start a plan and asked whether the sidewalk has to be in before starting the planting.
- Per Connie, we don’t have to return the $1000 to the donor if we don’t use it yet this year. It is expected that it will be used next year at latest.
Treasurers report – Bruce for Cheryl
- It is expected that we’ll have $54,000 at the end of this year.
- We can’t have a gross income more than $50,000 in a single year (we don’t have to worry).
- We will be using $1,000 for printing and mailing the fall newsletter.
Website Overview – Jason Houle
- Jason showed the website currently in development that is expected to be rolled out in early 2021.
- Since generating income is a top priority, the website makes dues payments easier and has options for automated repeat payments so members don’t have to remember and the board doesn’t have to send out reminders. There is also a donations choice for those who are not Association members. The plan is to put signs up at the boat launches to show how they can contribute to the GLA to keep the lake in good condition.
- There will be small thank you gifts with the Green Lake symbol on them for those who contribute.
- The site also includes a history of Green Lake and many year around pictures.
- BOARD: HAVE ALL ARTICLES TO CHRISTINE BY FRIDAY, SEPT. 18.
