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.Clear L: Kawartha Park2006 E.coli Lake Water TestingE.coli/100 mLSite No. 13-Jul-06 18-Jul-06 1-Aug-06 9-Aug-06 6-Sep-06A 0 0 0 0 0B 0 1 0 0 2C 0 0 0 2 0D 3 32 8 4 2P 0 0 2 0 0S 6 1 2 0 0Clear Lake: Kawartha ParkAs in previous years, counts were uniformly low.
