If I’m seeing a lot of foam washing up along my shoreline, is it possible that someone is dumping detergent into the lake via wash water?
It is possible, but not likely. The more likely explanation is that you are seeing what is called “lake foam.” The bubbles are actually organic material in the water column that has been agitated by wave action into a foam-like substance. It is neither toxic, nor unnatural, and is seen on virtually every relatively large lake in the county that experiences wind or boat-driven wave action.
