HAPPY DRAW. Happy Draw rises in southern Randall County (at 34°46' N, 101°59' W) and runs southeast near Happy and then northeast for twenty-one miles across northern Swisher County before reaching its mouth on the Prairie Dog Town Fork of the Red River, in southwestern Armstrong County (at 34°49' N, 101°32' W). Happy Draw is said to have been named by cowboys on cattle drives who were happy to find its spring-fed stream. The stream runs through terrain with shallow depressions and variable soils. Local vegetation is sparse with occasional areas of grasses.
