Complaints about aquatic vegetation in suburban and urban environments are common, with the City of Champlin's <br />Mill Pond being a good example. In this case, the concern went beyond just the appearance of the surface water, as <br />the vegetation inhibits swimming and fishing, and causes other problems. Attached is the City of Champlin's FAQ <br />which provides background on some of their attempts at addressing the situation. <br />Often due to frustration, residents and officials will try any means to reduce the amount of aquatic vegetation in <br />wetlands and sediment ponds, including aeration - usually with little effect. In the instance of the Mill Pond, three <br />very large aerators have been installed, again with no apparent improvement on the amount of aquatic vegetation in <br />the pond - despite the fact the Elm Creek flows 'new' water through the pond at a present rate of about 3 million <br />gallons per day. Attached is a photo of the Mill Pond at the point where Elm Creek flows past one of the aerators. <br />Funding Source: <br />This case does not discuss or request funding. <br />Recommendation: <br />Staff recommends no change in storm water pond maintenance practices at this time. <br />Action: <br />Based upon committee discussion. <br />Eutrophication Sign <br />Sunfish Lk Wter Quality <br />Stormwater Sign <br />complaint area <br />Sept.
