Good Evening Swampers,
I haven't had the priveledge of diving with you yet, but hope to do so soon.
Let me preface this post with a qualifier: I have a stupid question.
Most of my diving has been limited to ASP, CSSP, and a dozen or so blue water dives. I've never dove lakes, and am curious...what the heck is there to see at 100ft. with 5ft. viz? I'd be so consumed with trying not to lose my buddy, I doubt it would be any fun.
Anyway, there's my question.
Later swampers.
Ians answer was pretty spot on, but I will add a couple of things from my perspective.
I learned to dive in Travis, and dove only central texas locations for first 4 years of diving. Until you go bluewater and realize what you are missing, Travis is a great dive. And in summertime, you want to drop down below thermo for a little just to get out of the surface bathwater temps. Plus, as others have stated, when vis gets good below the thermo, it is nice to be able to take a look around.
When the vis sucks still, is always good for practicing navigation, bouyancy, or other skills. And it will really make you appreciate tropical blue water diving. Nothing like having comfortable temps, great visablility, and so much to look at that you can't hardly decide what to watch.
When I finally started diving blue water, it almost ruined me for diving Travis. Diving Travis became for occasional skills practice and equipment checks before heading to BW. For last seven or eight years I dropped to average of 4-5 dive days a year(even less last couple), was always to broke or to busy to break free to blue water. I got so only Travis dives I was doing was the occasional recovery or dock re-anchor for friends.
However, recent Christmas trip to Coz' saved me, this time rather than BW blinding me to the more subtle diving discoveries to be had in local lakes it reminded me that diving is always fun, and while Travis is definately not Coz' or Caymans, it is available, inexpensive, and still offers plenty of opportunity for wonder, albeit a bit less spectacular than ocean locations.
Now I just have to finish updating some of my gear, and my buddy list so can get out and dive more often.
