Has the quality of the lake been improving over time or is it getting <br />worse? How does Snail Lake compare to other lakes in Shoreview? These are questions that <br />Shoreview residents often have. I would like to share information with you to help answer these <br />questions and let you know what you can do to improve the quality of Snail Lake. <br />Overall, Snail Lake is showing a significant improving trend according to Bruce Wilson, <br />environmental research scientist with the Minnesota Pollution Control Agency. This is based on <br />an analysis of phosphorus data and lake transparency data collected by citizen volunteers and <br />lake scientists. Attached are plots of Snail Lake showing the average transparency and <br />phosphorous values for each year that data was available over the last 24 years. Only lakes with <br />four or more years of data were assessed. <br />This is how Snail Lake compares with other Shoreview lakes.* <br />Fake Water Quality <br />Trend <br />Owasso Highly significant <br />improving <br />Turtle No trend <br />Snail Significant improving <br />Grass Not enough data (one <br />year) <br />Wabasso No trend <br />bake Water Quality <br /> Trend <br />Island North Highly significant <br /> improving <br />Island South Somewhat significant <br /> -weak improving <br />Emily No trend, negative <br /> (degrading possible?) <br />Judy Not enough data <br /> (three years) <br />*If ycu are interested in more detailed infor~riation about the Lake trend al;alyses, contact Todd Howard, Ciry of <br />Shoreview at 490-4652 car visit the Shoreview web page at WWW.CI.SHOREVIEW.MN.US. <br />This analysis seems encouraging -overall it seems our lakes are improving. I~owever, tHis <br />improving trend could turn into a degrading trend if we are not careful. In very recent <br />years, Shoreview has seen a surge in development of the remaining vacant lands and this will <br />mean more fertilizers, pesticides, anti road and parking lot runoff entering into our lakes. Nearly <br />all storm water runoff from roads, parking lots, and lawns directly enters cur lakes. Also, lake <br />recreational usage has increased which means more pollutants from watercraft. These factors, <br />plus others, negatively affect the quality of our lakes and we must take measures now to counter <br />their impact. <br />
