You'll learn to appreciate Cozumel much better after diving in Travis.
Besides, how do you keep in practice?

Blue water diving is nice, but not all of us can live in Florida.  And
for some of us here, Lake Travis would be warm, clear water.

I'm trying to put together a group for right after school lets out
next May.

Speaking of cold lakes... A friend of mine asked me to dive in the
pedernales river last week to help him locate a cement dock anchor. I
solo dived and there was no way to buddy dive even if I had one.

At 5 feet the water was a pleasant green color with 1 foot vis.

At 10 feet I could hardly see half a foot

at 20 feet I could not read my gauges anymore

at 27 feet it was pitch black like night time and I could only see my
flashlight if I shined it into my mask from 3 inches.

at 30 (bottom) I groped around and in about a half hour I felt something
with a right angle and that was the anchor! I tied off a line to it and
ascended.

I could not believe it was pitch black at 30 feet. It was very strange
indeed. Also it was good practice to work completely blind. I connected
a steel cable with 2 ubolt fittings with a wrench and never saw any of it.

I had an extra tank and dove off the shore at my house on lake travis
near Bee Creek and it was not a whole lot better. 2 foot vis at best.
I've done a lot of dives from that same shore and have experienced vis
of up to 12 feet.

To be fair there was a lot of wind last week!
