Austin is awesome !!
I lived there for 2 years back in the '70's ( am I dating myself?).
That was prior to discovering the joys of owning a boat. We used to go tho the lake (there are 3 around the town) and watch boat races almost every weekend. It was great. That has been a few years ago, but the lakes are still there. I have no doubt they are crowded, since it's only a puddle in Texas compared to the real lakes in Oklahoma!! Just kidding. Austin is a great place to live.
Best of luck to you.
