Lake fly fishing

[Jack]

Lakes can be harder to read than streams. Maybe just different.
The first things I'd look for is a stream running into the lake. That may form a delta, or colder water running into the lake.
Probably the second thing I'd look for is a point.
One thing to think about in a lake is depth, i.e. , how deep are the fish you want holding? Since there are temperature variations in a lake, the fish will seek the temperature they are comfortable in. Usually, deeper means colder.
There are exceptions to that. A stream may put colder or warmer water into the lake at the stream mouth, and wind can pile up warmer surface water on the downwind side of the lake.
Obvious structure like logs, holes, etc is always worth checking out.
