DECKER CREEK. Decker Creek rises a mile east of Austin in eastern Travis County (at 30°19' N, 97°38' W) and runs southeast for ten miles to its mouth on Gilleland Creek, one mile south of Dunlap (at 30°15' N, 97°33' W). The creek was dammed in 1967 to form Decker Lake; the reservoir was renamed the Walter E. Long Lake in 1978. The local terrain is generally flat with local shallow depressions and is surfaced by clay and sandy loams that support water-tolerant hardwoods, conifers, and grasses.
