Lake Water Quality 2006 Report - Lakefield Herald

To put the results in perspective:• 100 E.coli/100 mL is the level at which public beaches are posted unsafe for swimming;• Kawartha Lake Stewards Association believes the safe swimming level for our lakes should be more stringent than this,and have set the acceptable level at 50 E.coli/100 mL. KLSA regards counts over 50 as cause for concern;• Counts 20 and below, with an occasional reading between 20 and 50, are normal for the Kawartha lakes;• A “-“ indicates no data available for that date.Sturgeon L: North Shore Combined GroupSite No.4-Jul-062006 E.coli Lake Water TestingE.coli/100 mL10-Jul-0617-Jul-0624-Jul-0631-Jul-068-Aug-061 22 - 67 0, 1, 2, 0, 4 3 202 8 - 117 45, 64, 60 2 11356, 47,532A 74 22, 18, 5 2 18 15 413, 13, 163 52 - 24 12 33 16 114 4 - 0 1 1 0 05 42 - 63 2, 3, 3, 5, 1 0 316 4 - 5 0 2 0 0SPGOLF 2 - - 0 1 0 0SPPD 2 - 7 4 4 12 3WS1 40 - 111 218, 6 1 47186,201,175,192SB1 216 38, 32, 16 207 17 9 827, 30,55SB2 20 - 5 10 1 11 15-Sep-06Sturgeon Lake: North Shore CombinedMost of the sites on Sturgeon Lake would be considered normal for the KawarthaLakes, with most counts below 20 and one or two counts between 20 and 50. However,Sites 2, SW1 and SB1 had higher counts than this over the summer, and have hadhigh counts at least once before.Site 2 is an open grassy area where Canada Geese congregate. The owner is trying todiscourage waterfowl, but the problem continues.78
