Low alkalinity
High alkalinity indicates water fertility and can signal the presence of larger trout. Fish in alkaline waters have a wider variety of invertebrates to feed on.
Shallow
The depth of a lake has significant impacts on its ecology. Reduced heat and light in deep lakes inhibit algal growth.
Low shoreline complexity
A lake with a high shoreline complexity will have numerous bays, points and peninsulas.
Mid elevation
Lakes at a higher altitude can take longer to warm up during the season and may not fish well until summer.

Larger lakes with good spawning often contain lots of smaller trout. Smaller lakes with limited spawning can produce larger trout.
