2 9/28/2022 VI. Old Business A. CBLID web page on City of Orono website: Nielsen discussed and displayed on a monitor the CBLID web page that the City of Orono main- tains for us. The City has been very cooperative regarding the CBLID presence on their website. The CBLID web address is: http://www.ci.orono.mn.us/423/Carman-Bay-Lake-Improvement-Dis- trict-CBL. Or, simply go to the City of Orono web site, and do a search for “Carman Bay LID”. The site includes information on all documents that established the LID, the purpose of the LID, bylaws, a map of the LID coverage area, board meeting minutes, annual reports, and more. Also on the city site is a nice feature titled “Notify Me” which, if you sign up, the city will send you an email anytime a notice is published regarding an organization or city committee you select. On the site select “notifications” and the organization, in our case Carman Bay LID, and you will receive notifications of meetings, treatments or whenever we publish a notice. The city is very supportive of the LID. The city also includes liability insurance for the LID on their policy, at no cost to us. There are only two LIDs on Lake Minnetonka, St Albans Bay and us. There are 112 properties in our LID. The LID eliminates the problem of raising money every year for aquatic invasive species treatment. VII. New Business A. 2022 Carman Bay treatment update Nielsen described the 2022 CBLID Bay treatment. Each year has different challenges. In 2022 there were a number of challenges including: very low water level that provides more sunlight to the lake bottom and helps the plants grow faster, very windy conditions on scheduled treatment days which dilutes the chemicals, high water clarity providing more sunlight to the lake bottom that helps the plants grow faster, and also a later ice-out date and cool spring causing a later start to plant growth, especially milfoil. Currently our LID is treating for two identified invasive species in Carman Bay, Eurasian Water Milfoil (milfoil) and Curly Leaf Pondweed (CLP). The CLP comes early in the season and milfoil later. Before treating, we must have a delineation survey completed for CLP and later for milfoil to create maps showing where the CLP and milfoil are located. These surveys are done by a separate entity, Fresh Water Scientific Services, not our treatment applicator, PLM. CLP was delineated May 19. Nielsen displayed the CLP location and treatment map on the monitor. CLP was treated with Diquat, a contact and broad-spectrum herbicide that can kill other plants as well. We must be judicious where we use it. The CLP was treated June 1, and was mostly gone by July 1. Milfoil as mentioned had a delayed start this year which dictates when the delineation survey can be done. If the survey is done too early, we can miss some of the milfoil. So that is a balancing act we must consider with our goal of treating the bay by early July to get the benefit of good control for peak summer. The delineation survey for milfoil was done June 17. There was a lot of milfoil in the northwest corner of the Bay, Casco Cove, Kelly Cove, and on the western shore of Carman Bay. All of these areas were treated July 1 using ProcellaCor in combination with Diquat. ProcellaCor is a systemic herbicide that is very specific in killing milfoil but not native plants. The DNR and our applicator, PLM, both like ProcellaCor for this reason. It can sometimes eradicate milfoil in some treatment areas. It is expensive, but with the DNR Grant money covering the additional cost, we chose to use more of it. Each year after the treatments, in early August, we have a Point Intercept Survey done that maps all existing plants by location and type. This survey has been completed, but the map of the location of
