We started the day intending to paddle on Sheldon Reservoir, a sheltered shallow flood-control lake, to view the many water birds and perhaps an alligator or two, but the lake was grown over with water plants and we didn't want to be pushing through...so we went down to Green's Bayou near where it crosses under I-10 and put in at a little neighborhood park.
It was an unseasonably cool day in the upper 70's. At 7:45 when we pushed off from shore. There were several different kinds of ducks in the water. It took only about 10 minutes of paddling upstream (the bayou is tidal at this point and there was no flow) before escaping the docks and backyards of the neighborhood into what appears to be untouched wetlands. We knew there was industry out of sight behind the trees, but it at least seemed natural, which is difficult to find near Houston. There were mullet jumping, gar and carp here and there, herons, egrets, and other water birds flying out ahead of us. We only had about an hour that morning so we paddled no more than a mile or so before turning back, but it was an enjoyable way to spend the morning soaking in a little nature before returning to our urban/suburban lifestyle.
No accomodations, no facilities. Bring your own water, snacks, etc. and pack it out. There are nearby restaurants on the highway as well.
No fees or permits.
On I-10 east of downtown, exit Uvalde and take the highway frontage road to Westmont Street. Turn right and follow it about a half-mile to the park on your left. Park, put in, and paddle!
