An even grey lid over the water, with a light E breeze and pressure easing off. Give the dam face and creek arms the first hour at Soil Conservation Service Site 21 Reservoir. The productive run goes the day. Start on the obvious water and expand from there. Falling temperatures are switching fish back on.

In Texas, Soil Conservation Service Site 21 Reservoir belongs to Williamson County. Elevation runs to 643 feet. About 7 acres of surface, which puts the far bank inside easy sight. On size it sits at the modest end of our Williamson County list. Some 2.7 miles away sits Hutto, the nearest settlement. The big place round here is Round Rock, 7.5 miles distant. The boundary is close enough to be worth checking before you fish.
Depth here is unknown, so count the lead down before committing. Held water runs deepest at the wall and shallows back to the inflow. The arms fish better than the open middle whenever the water is up. Species logged nearby in open biodiversity records include bluegill, black bullhead, green sunfish and Rio Grande longear sunfish. Records show what people reported, so treat the list as a guide to what lives in the area. At this water light and wind decide more than tackle does.
The warmest month averages 84°F, the coldest about 48°F. Cooler months are the productive ones on most of this water. Shade and hour of day matter more than month. February into May fishes hardest as the water warms. The season on this water follows the weather closely. Late evening often out-fishes the whole afternoon.
The access position is unclear from public sources. Parking is not close: half a mile from the bank, and no nearer option is mapped. Bass water: a Texas-rigged worm near cover, a spinnerbait when you need to cover ground. Some banks are open only from a marked point. Some ground is open by custom rather than by right, so tread carefully. Soil Conservation Service Site 22 Reservoir sits 1.4 miles off and takes the overflow. Rules at this water are worth checking on the day.
