City of Centerville <br />Council Meeting Minutes <br />June 9, 2021 <br /> <br />Mr. Bob Schack, 6941 LaMotte Dr., Lino Lakes, from the Centerville Lake Homeowner’s <br />Association (CLHOA) and Mr. Matt Kocian, Rice Creek Watershed District (RCWD), are in <br />attendance to present information on a proposed treatment to Centerville Lake to improve water <br />quality. The CLHOA would like to gauge the City’s interest in participating in the cost of these <br />types of activities. <br /> <br />Mr. Schack, thanked the City Council for their time and stated the CLHOA was reactivated in <br />order to help protect the water quality of Centerville Lake. They are working hand-in-hand with <br />the RCWD. The Association feels the lake is an important piece of the geography of Centerville <br />and the lake has a bigger issue than simply the weeds. <br /> <br />Mr. Kocian, shared information on what the CLHOA is working on. He stated that they are <br />working on algae removal, water quality monitoring samples 2 times a season. The decreasing <br />water quality has been a declining trend for approximately 10 years. This is quite unusual but it is <br />happening. They are putting together two (2) projects which include: a water reuse project and <br />shoreline stabilization along the eastern shoreline to assist with this problem. They are requesting <br />to treat invasive species, with a treatment of aluminum sulfate which binds up the nutrients so the <br />algae cannot bloom. He has not yet defined a budget or timeline. <br /> <br />Administrator Statz questioned the cost. Mr. Kocian replied with a very rough estimate of <br />$800,000. This would be a one-time cost and he estimates it would last 10-20 years. <br /> <br />Council Member Koski wondered if Peltier Lake has the same problem. Mr. Kocian stated it is <br />holding steady. He also noted the primary cause of degradation in Centerville Lake is invasive <br />species. The other change is that the old alum treatment is wearing off. <br /> <br />Council Member Koski expressed concerns regarding run-off and identifying a cause to help <br />eliminate having to do it again. Mr. Kocian mentioned that sediment in the bottom of the lake is a <br />source of contamination also. <br /> <br />Council Member Mosher questioned whether the alum treatment would harm fish, water for <br />swimming, or people. Mr. Kocian stated it is safe to use in lakes. He also noted there have been <br />studies, no animals have been harmed by this treatment and it is safe to drink. <br /> <br />Council Member Mosher questioned whether to give the alum treatment a little at a time or all at <br />once. Mr. Kocian explained when it was done in 1998, the dosage would be considered a spoonful. <br />Now, it would be 4-5 times that. He also noted that clarity would be seen immediately and this <br />treatment would last 20-30 years. City Council Mosher wondered when the treatment needs to be <br />applied. Mr. Kocian replied following ice out or late in the fall because it moves around on the <br />bottom more. <br /> <br />Mayor Love questioned if Mr. Kocian had spoken with the City of Lino Lakes who owns more of <br />the surrounding area of the lake. Mr. Kocian had not yet spoken with them and stated that when <br />the times comes, he would engage all the players. Mayor Love wondered what Mr. Kocian is <br />seeking from City Council this evening. Mr. Kocian stated he is here to provide information. <br /> <br />Page 2 of 7 <br /> <br /> <br />
