“He said that of the three types of lakes, namely, eutrophic, mesoptrophic, and oligotrophic, Eutrophic lakes are the one that are usually fished for trout.

Eutrophic lakes are shallow and usually have intermittent or no inlets or outlets, which means that they have low flushing rates. The soils and geology around it make them nutrient-rich so that they grow insects and other food sources of fish…..If you want to catch trout during spring, Chan’s advice is to be aware of spring turnovers. This is when a lake has a lot of debris in the water. “You can go down lower in elevation to catch a lake that’s already turned over or you go higher in elevation to catch a lake that hasn’t turned over,” he said.

Trout are usually found above the so-called thermocline, an invisible barrier that forms like a sheet of plastic across the lake. According to Chan, in most eutrophic lakes, productive lakes do not often have a lot of oxygen below the thermocline. Sometimes, there is not even enough oxygen to support trout in that area.”
