Spring Lake is a natural spring-fed lake that has been a focal point of human activity for thousands of years. The lake is fed by the San Marcos Springs, which are among the largest artesian springs in the world. These springs have been a vital water source for Native American populations for over 12,000 years, making it one of the oldest continuously inhabited sites in North America.

In the 19th century, the area around Spring Lake became a popular resort destination. The springs were harnessed to create an amusement park known as Aquarena Springs, which featured glass-bottom boat tours, a swimming pig named Ralph, and the famous Aquamaids, who performed underwater shows. In 1994, Texas State University purchased the property and transformed it into the Meadows Center for Water and the Environment, focusing on education, research, and conservation.

Spring Lake is home to a unique and diverse ecosystem that includes several endangered species. The crystal-clear waters of the lake provide a habitat for species such as the Texas blind salamander, San Marcos salamander, and fountain darter. The lake's aquatic vegetation, including Texas wild rice, is also of significant ecological importance.

The clarity of the water, which maintains a constant temperature of around 72 degrees Fahrenheit year-round, creates ideal conditions for both plant and animal life. This stable environment supports a complex food web and offers divers an unparalleled opportunity to observe these species in their natural habitat.

Scuba diving at Spring Lake is a unique experience due to the lake's clear waters, stable temperatures, and rich biodiversity. The diving spots in Spring Lake are categorized into five distinct areas, each offering unique features and attractions:

1. Archaeological Site: This area allows divers to explore underwater archaeology, where they can see prehistoric artifacts and learn about the ancient history of the region. Divers may encounter stone tools, projectile points, and other remnants of early human activity.
2. Aquarena Springs: Divers can explore the remnants of the old amusement park, including the submerged infrastructure of the glass-bottom boat tours and the underwater theater where the Aquamaids once performed. This area is a fascinating blend of natural beauty and historical artifacts.
3. Deep Hole: As the name suggests, this spot features a deeper part of the lake, offering a chance to dive down to depths of around 30 feet. The Deep Hole is a great spot for observing the lake's diverse fish population and aquatic plants.
4. Catfish Hotel: This area is named after the large catfish that inhabit it. Divers can expect to see a variety of fish species, as well as turtles and other aquatic life. The Catfish Hotel is a favorite spot for underwater photography due to its vibrant and active ecosystem.
5. Riverbed: This site allows divers to follow the course of the San Marcos River as it flows out of Spring Lake. The Riverbed is known for its strong currents and is an excellent spot for drift diving. Divers can observe the transition from the lake to the river ecosystem, witnessing changes in plant and animal life.

Spring Lake is not just a diving destination; it is also a hub for environmental conservation and education. The Meadows Center for Water and the Environment, which oversees the lake, is dedicated to preserving this unique ecosystem and promoting sustainable practices. The center offers a variety of programs aimed at educating the public and training divers in conservation techniques.

One of the key programs is the Spring Lake Dive Authorization Course (DAC). This course is mandatory for all divers who wish to dive in Spring Lake. The DAC provides an overview of the lake's history, ecology, and the specific rules and regulations for diving in this protected environment. Divers are trained in techniques to avoid disturbing the delicate ecosystem and to contribute to ongoing conservation efforts.

The Meadows Center also runs the Spring Lake Clean-Up Dives. These events, held regularly throughout the year, invite certified divers to assist in cleaning the lake. Participants help remove debris and invasive species, contributing to the health and sustainability of the ecosystem.

Additionally, the center offers educational programs for students and visitors. The Discovery Hall features interactive exhibits on the natural and cultural history of Spring Lake, while guided tours provide insights into the lake's unique features and the importance of water conservation.

Diving in Spring Lake is a truly unique experience due to the combination of historical artifacts, vibrant aquatic life, and crystal-clear waters. The constant temperature of the lake allows for comfortable diving year-round, and the visibility is often exceptional, ranging from 50 to 100 feet.

Before diving, participants must complete the Dive Authorization Course (DAC) to ensure they understand the importance of protecting this sensitive environment. This training emphasizes buoyancy control and proper finning techniques to avoid disturbing the sediment and aquatic plants.

Once in the water, divers are treated to a serene and almost otherworldly experience. The lake's calm and clear waters provide a peaceful backdrop for exploring the underwater landscape. Divers can glide over beds of Texas wild rice, observing the delicate fronds swaying with the gentle currents. Schools of fish, including sunfish, bass, and catfish, move gracefully through the water, while turtles can be seen basking on submerged logs or swimming lazily by.

One of the highlights of diving in Spring Lake is the opportunity to see the endangered species that call this lake home. The San Marcos salamander, with its striking red coloration, can often be spotted hiding among the rocks and aquatic plants. The tiny fountain darter, another endangered species, is known for its intricate mating displays and can be seen darting through the water in search of food.

For those interested in underwater photography, Spring Lake offers a wealth of opportunities. The clear waters and abundant light create ideal conditions for capturing the vibrant colors and intricate details of the underwater world. Photographers can document the various species, underwater landscapes, and historical artifacts, creating lasting memories of their dive.
