The most-shared photo each summer in North Alabama neighborhood Facebook groups is a snake in someone's pool. It looks alarming. It is almost always one of two species, and the situation is almost always resolvable without drama.
The species in the pool
Nine times out of ten it is a northern water snake — non-venomous, defensive, and an excellent swimmer that may rest on the surface or against the pool wall. The tenth call is sometimes a cottonmouth, especially on properties near a creek or pond, and very rarely a copperhead that fell in by accident and cannot get out.
How they end up there
Pools are a thermal sink — cooler in summer than the lawn, warmer in spring than the air at night. A snake working the yard perimeter encounters the rim, slips in, and then cannot grip a smooth wall to climb out. Without a ramp or a step, the snake stays in the water until it tires.
Yard sightings — what is really happening
Open-yard sightings come from three causes. Rodents — voles in the lawn, mice in the woodpile, chipmunks under the deck — produce the prey trail. Harborage — landscape rock, dense ground cover, woodpiles touching the foundation — gives the snake daytime cover. Travel routes — fence lines, retaining walls, and drainage swales — funnel snakes across the property.
Removal and prevention
For pool snakes, we use a long-handled tool and a containment bag, identify the species, and relocate non-venomous individuals. Venomous individuals are removed under different protocol. For yard work, the inspection focuses on rodent reduction, harborage clearance, and entry-point sealing. See our snakes activity guide for the season for the seasonality piece — most of these calls cluster in June and July across North Alabama.
Lake-adjacent properties have higher baseline snake activity year-round. Snake work in the Guntersville area looks very different from snake work in an inland subdivision — both are real, but the species mix and the entry patterns differ.
One concrete prevention upgrade
A simple pool-edge ramp — even a piece of foam pool noodle tethered to the ladder — gives small animals (snakes included) a way to climb out. It does not stop them from going in, but it dramatically reduces the chance of finding a drowned snake at the bottom of the deep end the next morning.
