Beautiful-Fish,
The lakes you mention all have one thing in common - the water tends to warm up in the summer. Rainbow trout get stressed in the warmer water and start to shed some of their slime covering. When this happens, they are much more susceptible to attacks from the myriad of microbes that occur naturally in the lake. The problem is made much worse during low water years when the fish can be additionally stressed by heavy algae blooms, increased turbidity, and lower oxygen. Most of the fish will recover from these attacks once the water cools down in the fall, but occasionally we do see some mortality.
Hope this answered your question.
