PARKERS CREEK. Parkers (Parker, Parkus) Creek rises (at 29°30' N, 99°16' W) twelve miles north of D'Hanis and four miles west of Texas Mountain in far northwestern Medina County and runs south for twenty-five miles to its mouth (at 29°14' N, 99°16' W) on Seco Creek, seven miles south of D'Hanis and three miles west of Farm Road 462. In its upper reaches near Farm Road 1796, the creek has been dammed to form Parkers Creek Lake. Along its upper reaches grow oaks, junipers, and grasses; toward the creek's mouth are scrub brush and various grasses. The stream initially passes through rolling prairie and then enters steep to gently sloping terrain.
