Description - Don Johnson
In the River Ridge subdivision off Leander Road (RR 2243) on the outskirts of Georgetown there is an undeveloped city park on the south bank of the South San Gabriel River. There is an entrance to the park on River Down Road at its intersection with Rim Rock Drive. This entrance is merely a gap, about half the width of a normal lot, between two houses; the entrance looks like it could be a side yard of one of the adjacent houses (see photo). The entrance is unmarked except for a sign prohibiting some things, like paintball guns, on city property. As you walk through the entrance toward the river you will come to a moderately steep hill where a very rough trail descends the river bluff down to the river bottom. This hill is strewn with rocks and small boulders (see photo) offering a good chance to sprain an ankle. At the bottom of this hill a footpath leading toward the river intersects with an old pickup road. If you go a few hundred yards upstream on this road you will come to a wide opening in the trees that leads down almost to the river. At the end of this opening you will have to look around a bit to find a footpath that goes the last few feet to the riverís edge. Like most places on the upper San Gabriel system, this is a very pretty place, with clear water and nice scenery. Before you take off fishing be sure to remember what your beginning spot looks like; there are no obvious markings, and it would not be difficult to walk on past it when on your way back.
At normal flow levels, say anything less than 40cfs, you can wade from here all the way down to the I-35 crossing, and beyond . There is a gravel quarry upstream, and I am not sure what the wading and fishing is like up that way. You can check the river's flow rate at the USGS gauge downstream at I-35.
