Gem Lake <br />Gem Lake is within the City of Gem Lake and has no public access. It is 25 acres in size and is 10 feet deep. There <br />has been development along portions of the lake in recent years. In 2000, volunteers noticed a distinct algae bloom <br />and noted that water clarity was getting poorer. <br />Two samples that were collected in mid -summer 2007 were found to have an enormous amount of TP and Chl A. <br />Dave Schuler, Chief Engineer at SPRWS, recommended the results be eliminated from the data because the results <br />are nearly impossible to achieve and human error likely caused the samples to be contaminated either in the collection, <br />transportation and/or laboratory. Therefore, we have removed the TP and Chl A results from these two weeks while <br />calculating the annual averages but we will keep it on record to compare with future results. <br />
