Brantley Lake State Park (Click Here for Park Page)

Description: 3,000-acre lake on the Pecos River 6,500 acres at flood pool. Brantley Dam is on the Pecos River at mile 478.5, about 13 miles upstream from the city of Carlsbad, New Mexico. It is about 10 miles upstream from the Avalon Dam in the Carlsbad Project and 25 miles downstream from Artesia.

The Brantley Project area extends about 16.5 miles above the damsite. The Pecos River watershed is in a semi-arid region. Average annual precipitation in the Pecos River Basin varies from about 10 inches near Pecos, Texas, to greater than 33 inches in the higher mountain elevations of northern New Mexico.

The project´s main purpose is to replace McMillan Dam, which was declared unsafe. Additional benefits include irrigation, flood control, fish and wildlife enhancement, and recreation.

Recreation Areas Managed By: New Mexico State Parks

Lake Information (Land Status, Dam Operator): The State Park is located on leased land owned by BOR.  The Carlsbad Irrigation District is the water regulator managing the lake depth.

Formerly McMillan Dam and Reservoir  Rehabilitated in 1908, this zoned earthfill dam was 57 feet high and had a volume of 234,000 cubic yards. The reservoir capacity as built was 82,600 acre-feet but siltation had reduced the active capacity to about 33,600 acre-feet (based on survey of September 1964). The dam was located about 14 miles northwest of Carlsbad. When Reclamation completed Brantley Dam in 1991, Reclamation drained McMillan Reservoir and breached McMillan Dam.
