This dive site, the Lower Comal River, offers a unique freshwater drift diving experience a few dams downstream from the Upper Comal. Divers typically begin their journey by entering the water underneath the Garden Street bridge. The river guides divers through two distinct bends before reaching the last public exit, located just before the Comal merges with the Guadalupe River. It is primarily a linear drift dive, following the natural flow and topography of the riverbed.
The Lower Comal River is home to common Texas freshwater species, providing a glimpse into the local aquatic ecosystem. Divers can expect to encounter various fish such as bass, perch, catfish, and tilapia. Turtles are also a frequent sight, often seen navigating the river's currents or resting along the banks. The underwater environment consists of riverine flora and a substrate typical of a flowing freshwater system.
The best time to visit the Comal River for diving is during warmer months when water temperatures are more comfortable, typically from late spring to early fall. This site is excellent for beginner divers due to its shallow depths, while experienced divers can enjoy a relaxing drift. Freedivers will also find the shallow, clear-ish water and current dynamics suitable for breath-hold exploration. Be mindful of potential boat or tuber traffic, especially during peak seasons, and always be aware of your exit point.
