Mesotrophic lakes have an intermediate level of productivity and nutrient availability. They typically contain submerged aquatic vegetation and an intermediate level of algae. Sometime of these lakes are still very clear but others can become more turbid as sediments and organic material start to enter the lake.
This picture shows aquatic plants vegetating the lake bottom and how the water becomes less clear.
