The third primary tributary to the Little River is the
San Gabriel which forms in
Georgetown at San Gabriel Park — the confluence of the North and South Forks. About 20 miles east of Georgetown, the river is impounded at
Granger to form
Granger Lake. The river then flows about 30 more miles in a northeastern direction to its confluence with the Little River, about five miles south of
Cameron. The geography along the San Gabriel is varied, with heavy vegetation on its banks and occasional limestone bluffs in the
Balcones Escarpment of the
Blackland Prairie. Water levels fluctuate for the entire length of the river. Except during the dry summer periods, there is normally sufficient water for recreational use. Cities and towns along the San Gabriel include
Rockdale,
Thorndale,
Granger,
Taylor,
Georgetown,
Bertram, and
Burnet. The river was named Río de San Francisco Xavier by the
Ramon expedition in 1716 and is also recorded in the journals of the
Aguayo expedition of 1721. On his map of 1828
Stephen F. Austin mistakenly labeled the river "San Javriel" — his erroneous transposition of "San Xavier." From this, the name morphed into "San Gabriel." The
San Xavier missions were founded in 1745 along the river a few miles upstream from the mouth of Brushy Creek — one of the river's minor tributaries. In May, 1839 the San Gabriel was the site of the
battle of the San Gabriels, one of the state's most important Indian fights. Brushy Creek was the location of the
battle of Brushy Creek in February, 1839. The South Fork of the San Gabriel forms four miles east of
Burnet in
Burnet County running 34 miles eastward through
Williamson County before it joins the North Fork in
Georgetown. The North Fork forms 12 miles north of
Burnet in Burnet County and flows southward for 43 miles into
Williamson County to its confluence with the South Fork in Georgetown. The North Fork is impounded about three miles northwest of the confluence of the two forks to form
Georgetown Lake. The two forks are very similar. Both are scenic, winding rivers with numerous limestone bluffs. However, recreational use is restricted to periods of sufficient rainfall since they tend to not maintain consistent water flow. The San Gabriel has two other tributaries — the Russell and Middle forks. The Russell Fork begins six miles north of
Burnet and then flows into the North Fork. The Middle Fork forms five miles east of
Liberty Hill in
Williamson County and then flows east to its confluence with the North Fork about one mile west of
I-35 near the western city limits of Georgetown. Other seasonal tributaries of the San Gabriel include Brushy, Alligator, Opossum, Berry, Pean, Little and Oatmeal creeks. ==See also==
