Green Water and Eutrophic Lakes
Largemouths are comfortable in warmer, shallower waters. They are also efficient predators in algal bloom conditions. Come mid-summer under 78-to-82-degree water temps., largemouths from these waters feed heavily to maintain their robust weights.
Whenever I see algae-blooming waters while browsing on Google Earth, I want to go fish them. These lakes are common throughout agricultural regions, in glacial lake regions, and in drainage systems. My region of Wisconsin has a lot of these lakes. Some of them support great largemouth bass fisheries due to adequate depth and currents, while others suffer winter-kill events and mass die-offs in brutal winters to the point of no recovery.
Eutrophic lakes are exceptionally fertile, shallow, warm and heavily vegetated. These waters are personified by all of the nutrients and run-off that feeds into them, triggering summertime algae blooms and potential summer kills. Rarely deeper than 10 to 15 feet, they are bowl shaped and often lack well defined structure. They tend to have silted muddy bottoms, and may feature boggy and heavily submerged wooded shorelines and tannic stained water. They are heavily weeded with emergen
