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.Big Bald Lake2006 E.coli Lake Water TestingE.coli/100 mLSite No. 4-Jul-06 17-Jul-06 24-Jul-06 31-Jul-06 8-Aug-06 5-Sep-061 8 1 0 4 1 02 6 0 2 10 3 03 4 0 0 2 2 15 12 0 0 6 0 57 6 0 4 1 0 18 0 0 0 1 5 5Big Bald LakeAs in previous years, E.coli counts in Big Bald Lake were consistently low.Buckhorn L: Buckhorn Sands2006 E.coli Lake Water TestingE.coli/100 mLSite No. 3-Jul-06 17-Jul-06 31-Jul-06 8-Aug-06 5-Sep-06B 82 3, 7 63 47, ll, 8, 4, 7 0C 8 0 1 0 7D 4 3 3 6 0E 16 6 2 2 5Buckhorn Lake: Buckhorn SandsOver 6 years of testing 4 sites, there have been only 3 readings over 50 E.coli/100mL, all at Site B. There have been no obvious reasons for these elevated readings.It is interesting to note that there were 40 to 50 geese on shore near Site D on July17, but the reading was low.69
