The Rio Grande flows north to south through Sierra County. It flows into Elephant Butte Lake, through Truth or Consequences, into Caballo Lake and south through the agricultural area of Sierra County. Its water is the life blood of the agricultural industry of New Mexico south of Elephant Butte Lake and Dam.

Sierra County is a recreational paradise in the Southwest. The Rio Grande and the two lakes formed by it are prime fishing, boating, camping, birding and hiking locations. Rafting, kayaking and canoeing down the Rio Grande is a fun-filled scenic adventure!
