At 10:00 AM sharp, with our 20-foot Key West center console boat loaded with supplies for the day, we pushed off from the dock and headed north up the lake. The morning air carried a hint of desert sage mixed with the unmistakable freshness of water – a combination that never fails to invigorate my old bones and remind me why we choose to winter in this corner of Arizona.
As we navigated toward our favorite coves, I found myself reflecting on the smallmouth bass spawning behavior that has fascinated me since I first learned about it decades ago. These remarkable creatures, not native to these waters but thriving nonetheless, follow an ancient ritual when spring water temperatures climb into the upper 50s to mid-60s degree range.
The males arrive first to the spawning grounds, usually selecting areas with pea-sized gravel or small rocks in 3-15 feet of water. With determination that would impress any homebuilder, they create circular depressions in the substrate by fanning their tails – creating what anglers commonly call "beds." These underwater nurseries are carefully constructed and fiercely defended by the males, who turn noticeably darker during the spawning period.
When females arrive, typically when water temperatures stabilize around 60-65 degrees, the courtship begins. The male will swim alongside her, occasionally nudging her side, essentially encouraging her to deposit her eggs in his meticulously prepared nest. Once she releases her eggs – potentially thousands of them – he follows immediately with his milt to fertilize them. Sometimes multiple females will visit a single male's nest, adding to his paternal responsibilities.
