Anglers looking at St. Tammany Parish will find Foster Bayou, a lake, so the first move is to spend more time casting than relocating. I would give one nearby section of bank a fair chance before making a bigger move, because that keeps the day simple while the water is still unfamiliar.
Foster Bayou Size, Maximum Depth and Volume
Foster Bayou does not have a dependable set of published acreage, depth, and volume measurements, and that is a reason to treat the first outing as a chance to learn the water's scale, and I would rather judge the scale in person before making a long run. I would start by learning the shoreline before choosing a pattern, because I would plan modestly until the size of the water is clear.
Fishing This Water
Public fish information for Foster Bayou is limited enough that a species list should not be guessed, so the practical choice is to treat the first outing as a chance to identify the main targets, and I would rather let the first catches narrow the plan. I would carry a simple freshwater kit with a jig, a spinner, and a bait rig, because the goal is to find out what responds before narrowing the tackle any further.
A Practical Foster Bayou Game Plan
If I were seeing Foster Bayou for the first time, I would work one straightforward part of the water with only a few dependable baits; I would spend more time fishing a promising area than driving around looking for a perfect one.
