HAGGERTY CREEK. Haggerty Creek rises a mile northeast of Scottsville in east central Harrison County (at 32°33' N, 94°14' W) and runs northeast for thirteen miles to its mouth on the Gum Slough of Big Cypress Bayou, just west of Caddo Lake State Park^qv (at 32°42' N, 94°12' W). The stream's main tributaries are Karnack, Key, and Deboldin creeks. The local terrain is gently undulating to hilly, surfaced by loamy and clayey soils that support dense patches of pine and hardwood trees along the creek's banks.
