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.Buckhorn L: Sandbirch Estates2006 E.coli Lake Water TestingE.coli/100 mLSite No. 4-Jul-06 16-Jul-06 23-Jul-06 30-Jul-06 7-Aug-06 4-Sep-064 4 16 2 1 0 32 2 4 2 0 0 619 19 18 26 11 0 30Buckhorn Lake: Sandbirch EstatesCounts were uniformly low on all these sites, similar to previous years.Chemong L: Lakeside Common2006 E.coli Lake Water TestingE.coli/100 mLSite No. 4-Jul-06 11-Aug-06 11-Sep-06CC1 24 13 30Chemong Lake: Lakeside CommonThis is the first year of testing for this group. Counts were perhaps slightly elevatedcompared to most other KLSA sites tested in 2006 (where most counts were wellbelow 20), but more readings would give a better indication of the bacterial status ofthis site.70
