One can wonder at will without seeing another sportsmen or hearing the sounds of groaning four wheel drives inching closer to your sacred spot. It's as if the whole world stopped thinking about five pound trout by the score cruising very close to the surface. It is a natural fact as the water begins to chill to well under fifty degrees a wonderful transformation takes place. Most all species of game fish including trout no longer hide on the bottom where the cold water exists. In as much as fish in general are slave to water temperature variance.
Game fish adhere to temperature changes much like politicians listen to latest polls.
My least favorite fly fishing venue is lake fishing. The only solace is the early morning late afternoon rising fish and those jewelry like rings that evaporate and act as targets for those who love to throw dry flies. In my hometown of Marin County California we are lucky to have several water holding reservoirs that can be fly fished all year long. In the hot Summer months when I get the urge to throw bugs and want to forgo the three to four hour drive needed to access productive water. These local reservoirs do hold trout and are stocked on a regular basis.
