San Marcos River Headwaters

This is a video tour of the headwaters of the San Marcos River, just downstream of Spring Lake. Spring Lake is fed by Aquarena Springs, which provides extremely high quality water for the flora and fauna downstream of the lake.

I think you folks at AquaticPlantCentral.com will get a kick out of this video ; ) Being under the water at this place was everything that I hoped it would be. It's like being a minnow swimming around in a beautifully planted 200G tank.

Plants I'm fairly certain that I identified:

- Valisnéria Gigantea
- Cabomba Aquatica
- Zizania texana (Texas Wild Rice)
- Ludwigia repens (Red Ludwigia)
- Hydrocotyle verticillata (Whorled Marsh Pennywort)
- Cabomba Caroliniana (Carolina Fanwort)
- Ceratophylum Demersum (Hornwort)

...but there are many others!

Hope you like the video.

Why no comments allowed for your high voltage weed killer?

Also cannot leave a comment on your account.

I would like to kill dandelions without chemicals.

Any suggestions?

Was considering using 120VAC through a lightbulb (to prevent a direct short)

with a sharp probe into the root.

Would/does it kill adjacent grass which I do not want to harm?

Thank you.

Robert

Beautiful underwater scenery.

@robertgift: When I first created the channel, people's rude attitude prevented me from allowing any comments. Nowadays, I don't care as much...so older vid's not allowed, newer one's they're generally allowed. 120VAC through a lightbulb is a smart idea. Try 6" metallic rods into the ground as electrodes, and a high-power lightbulb (halogen 300W work-light!) to get some current flowing. You might not get enough to light the bulb, but I'm wiling to bet it's enough. Will prob. kill grass.

Are there any alligators in the water? I want to know if its safe to go in the water because I might go swimming there, and I know there are alligators in texas. Anyway, nice vid!

Awesome! What kind of snorkel/scuba gear did you use? Is this the city park? What area of the park, exactly? Thanks.
