FRIO DRAW. Frio Draw (Frio Creek) rises in eastern Curry County, New Mexico (at 34°50' N, 103°38' W), near the Texas state line, and runs east-northeast for fifty miles, passing through three Texas counties-northern Parmer, northwestern Castro, and southeastern Deaf Smith-before reaching its mouth on Tierra Blanca Creek, five miles east of Hereford in Deaf Smith County (at 34°50' N, 102°19' W). The draw traverses flat to rolling terrain surfaced by sandy loams that support grasses and mesquite. Although it is never a perennial stream, Frio Draw is subject to flash floods that have occasionally caused damage, particularly in Parmer County, where the draw passes just south of downtown Friona. Frye Lake, a small man-made reservoir, was built on the draw east of Friona to help control the flooding.
