Because bass are so abundant, their choice of spawning grounds is quite basic.
Water temperature is important for the spawn. It makes sense then, that the bass would go to shallow waters to prepare their nests. For the most part, nests will accumulate at depths of 1 to 4 feet (0.3 to 1.2 meters). But in clear water, bass have been known to nest as deep as 20 feet (6.1 meters) [source: Davis]. The farther down the nest, the less likely is it that waves or boats will interfere with the spawn, and the eggs will have a more stable environment. Unfortunately for the bass, this is only possible in clear waters, when the sun can reach more impressive depths. The sun's warmth is needed to keep the fertilized eggs incubated [source: Canning].
Come spring, the male bass will swim to warm, shallow waters. There he will seek out a clear area with a hard surface. Bass prefer rough bottoms -- such as gravel or rocks -- but in sandy areas they have no other choice [source: Canning]. Once he has found an area that will accommodate the spawn, the male bass uses his tail to clean the nest. Then he clears a circular area with a diameter that is two times the length of his body [source: Davis]. After he's constructed the nest, he'll begin to circle his territory in search of a mate.
Understanding where and when the bass spawn occurs is helpful to any determined fisherman. Read on to understand the best methods for reeling in great spawn-time catch.
