95Aggie, There are a couple small lakes (ponds) in Round Rock and Pflugerville that are pretty good for bank fishing. The only boats allowed on them are canoe or kyak.
Here is a link to the Austin Kyak Boards map section. Look under the Round Rock and Pflugerville lakes for maps. And it has other lakes in the area.
