During the five-day survey of Cameron Lake, August 17 to 21, 1970, the water was acceptable for recreational use. However, a cautionary note must be included to indicate a possible discharge of fecal material through the soil with a time lag between peak cottager population and appearance of pollution in the water. This discharge could cause a public health hazard and negate the acceptability of the lake for recreational use. Further investigation is required before this hypothesis can be proven or disproven. The Burnt River and Rosedale River had a large influence on the lake stations near their mouth.
