Spring Lake Diving
On September 1, 2023, we enacted dive restrictions for allowable dive numbers due to sustained low flows below 80 cfs. These restrictions were implemented per guidance of the Spring Lake Management Plan and the Habitat Conservation Plan.
Upon implementation of these restrictions, we have been monitoring the effects of these restrictions and how they have impacted the delicate environment of Spring Lake.
In consultation with the City of San Marcos, EAA, and USFWS, it has been determined that the reduction in diving activities and maintenance of the springs has resulted in putting a heavier strain on the springs and environment for the threatened and endangered species of the Lake. It has, therefore, been determined that allowable dive numbers and spring maintenance shall be allowed to resume to normal capacity.
Effective November 1, 2023, we will reinstate all diving activities to normal capacity in Spring Lake, ensuring we are maintaining and protecting the springs and environment of Spring Lake at an optimal level.
The Lake Manager will continue to monitor daily, and if sustained turbidity levels occur, safety or other issues arise from diving activities, a determination to cease or further reduce all diving activities will be assessed in collaboration with the Meadows Center Chief Science Officer and the SL Environmental Review Committee.

Spring Lake: Unique in the world.
At the headwaters of the San Marcos River, more than 200 artesian springs bubble up to form Spring Lake. Here, human history stretches back more than 12,000 years to the last ice age and natural history even further. Spring Lake is a jewel for divers.
Spring Lake at The Meadows Center for Water and the Environment is home to:
- crystal-clear waters that remain a constant 72 degrees year-round
- one of the world’s largest aquifer-driven spring systems
- seven threatened and endangered species
- a state antiquities landmark
- the longest continuously inhabited site in North America
- ongoing biological and archaeological research and many collaborative projects
- likely the densest population of turtles in the United States..and more
Our diving program partners with select scuba divers to protect and preserve Spring Lake's abundant natural, historical, and cultural resources. We train citizen scientist divers, and in return, they volunteer their time to one of the most unique habitat restoration projects in the country.

Friendly reminder to all Spring Lake instructors and divers: We need your Help! Please keep in mind that the public restrooms at Spring Lake are also used by faculty, staff, and our general public visitors. While we know changing out of wetsuits can be a messy endeavor, we appreciate your best efforts to keep the facilities as tidy as possible for the next person. As always, we appreciate your support at Spring Lake.
