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.Chemong L: Smith-Ennismore-Lakefield Ratepayers Assoc.2006 E.coli Lake Water TestingE.coli/100 mLSite No. 7-Jul-06 28-Jul-06DW 0 1MF 3 2SND 0 1CW 0 1Chemong Lake: Smith-Ennismore-Lakefield RatepayersCounts were very low at all 4 sites on the 2 dates, as they were in 2005.Clear L: Birchcliff Property Owners of Douro-Dummer2006 E.coli Lake Water TestingE.coli/100 mLSite No. 20-Jul-06 25-Jul-06 31-Jul-06 3-Aug-06 8-Aug-06 8-Sep-06BB 3 4 15 - 1 01 1 0 1 - 1 02 0 1 89 0, 1, 2, 4, 0, 1 1 03 0 2 3 - 0 264 0 9 12 - 0 665 0 2 2 - 40 06 0 1 1 - 0 07 1 0 1 - 0 08 0 2 1 - 1 3Clear Lake: Birchcliff Property Owners of Douro-DummerThe elevated readings for Site 2/July 31 and Site 4/Sep 8 had no apparent cause,and there is no history of high counts at either site.
