GRAYS CREEK. Grays Creek rises just north of Marshall in north central Harrison County (at 32°36' N, 94°22' W) and runs northwest for seven miles to its mouth on Little Cypress Bayou, three miles northwest of Woodlawn (at 32°42' N, 94°23' W). Grays Creek was probably named for Thomas Gray, who owned the land patent at the mouth of the stream. The creek runs through an area of gently undulating to hilly terrain surfaced by loamy and clayey soils used mainly for agriculture. Its banks are heavily wooded in places with pine and hardwood trees. Grays Creek was dammed three miles north of Marshall to form Holmes Lake, a reservoir with a capacity of 1,044 acre-feet; in the 1940s the lake was owned by the Texas and Pacific Railway.
