Streams entering a lake provide a food supply and a change in both water temperature and oxygenation. Also, inlet streams concentrate fish at spawning times. In inlet bays fish stack up during the pre-spawn. Inlet areas modify a lake’s structure from shallows to increased depths because stream channels erode winding paths through a lake’s bottom.
Fish are noticeably alert in these locations because birds of prey have learned that these are good areas to fish.
Incoming current stacks up against the lake’s stillwaters to create a mini-rip effect; in fact, these rip currents develop vertical walls of water which concentrate incoming foods. Its surface collection of flotsam is readily noticeable so this concentration of food will attract hungry fish.
Inlet areas are prime locations to fish, especially during low light conditions, warm temperature times, and pre-spawn periods.
