Certified divers who are interested in conservation are invited to take our Spring Lake Dive
Authorization Course. Those who successfully complete the course will become part of
The Meadows Center’s Aqua Corps and will work as citizen scientists to help maintain and
monitor the aquatic resources of Spring Lake. E-mail us at

You must take the Spring Lake Dive Authorization Course before you can dive here.

The course costs $230 but you are certified for life. There is no charge for future visits.

You have to have 30 logged dives to take the course. Before the course you have to
read a short book and answer some homework questions. It’s a one day course. Half
the day is classroom lecture and the other half is two dives. The course is easy but you
will need to demonstrate solid buoyancy skills during the first dive or you will fail. If you
pass the buoyancy tests the second dive is basically a nice guided tour.

San Marcos has hotels, restaurants, and everything else you need to stay here.

They have restricted hours of operation but you can get air fills and other scuba
support at The Dive Shop.

Interesting dive site ... loved the required class prior to the dives; history, geology, and diving, who could ask for more?

Three dives in two days. I visited the usual suspects: cream of wheat, ossified forest, ancient river bed, catfish hotel, arc site, and some unnamed sculptures/junk that was a little north of the training area. Lots of cleanup and zillions of fish. This is the best Texas fresh water dive.

There was so much silt after heavy coontail removal I’m not sure how much good I did but I tried to do some clean up at deep hole/arc site, catfish hotel, and cream of wheat. All I did was fan the silt off the sand. Hopefully it will drift down river. Wow was there plenty to see during general touring of deep hole, arc site, river bed, ossified forest, and areas I’m not sure of their name. Under the old dock I saw a school of 50 cichlids. Cool I had no idea they schooled before. There were zillions of bass, perch, and other fish. I also saw some turtles and an alligator gar. Vis was maybe 100 feet until we started stirring it up as part of maintenance efforts. This is an awesome dive site.

This is an amazing place to dive. The newly revised course is well worth the price. Taylor and Sam have put together a great new program.

The water temp is 72F year round. Viz was 60 ft. It’s a great course to take. Lots of plant and animal life.

I enrolled in the new Diver Authorization Course. I passed their tests and they took me a tour. We saw deep hole, catfish hotel, arc site, old river bed, cream of wheat, etc. This is a sweet place to dive. I will be back.

What kind of "in-water" tests did you do? Was the class educational and fun?
BillParker - 10/09/2014 2:43 PM
After I signed up I was sent some PDFs including a 100 page whopper. It took about four hours to go through the 100 page document on history, ecology, Texas and Federal law, etc. and answer almost 100 mostly multiple choice and fill in the blank questions. You have to have this done before you attend the class in San Marcos. The class started at 9am as scheduled. We spent from 9am to 1pm looking at slides, listening to lectures, and correcting the written tests we did before the class. They provided snacks, water, and coffee. If you didn’t bring a sack lunch they went to Jimmy John’s and picked up a sandwich for you. For only the fourth session of this new class they seemed well organized prepared. The indoor class was easy and time passed quickly. Around 1pm we headed to the training area of Spring Lake. We did two short dives. The first was various tests mostly to check you had good control of your buoyancy and demonstrations of maintenance tasks. We were observed doing a short reciprocal swim, passing through hoops without bumping them, and moving weights from one place to another. Then we were shown how to remove rooted plants, fan off algae, and use your octo to float up large plants. The first dive wasn’t that interesting but I got through it. The second dive was a guided tour and the funnest part. We followed the instructor through a series of sites including deep hole, catfish hotel, arc site, old river bed, cream of wheat, etc. There were more variety and quantity of

of fish and plants than any fresh water site I’ve been to. The vis was as good as Balmorhea State Park. We finished just after 5pm. I’ll get a certificate of completion in the mail. This class was just a start. When I return I’ll be paired with another senior volunteer diver to show me more maintenance tasks and supervise me to make sure I don’t mess anything up. The way it works is you don’t get to do a fun dive and just observe until you contribute something like removing unwanted plants.

They are offering access classes there again for new divers.
