This is a technical design document for the Melstone Dam Livestock Water System, a Bureau of Land Management (BLM) project located in Musselshell County, Montana, under the BLM's Billings Field Office. The document consists of three sheets containing plans and profiles for a livestock water infrastructure system.

The project includes the installation of a livestock water inlet system with associated pipeline infrastructure, water storage tank, and distribution components. Key technical specifications include a 1,300-gallon storage tank, 4-inch HDPE gravity feed pipe from the inlet, an 18-inch annular corrugated metal pipe (CMP) riser with a pitless adapter, a sealed electrical conduit to a 300-watt solar bank, and water quality monitoring signage. The system incorporates a two-stage riprap and sand filter inlet structure with perforated PVC piping, compacted backfill, and geotextile fabric. Additional infrastructure includes an 18-inch CMP riser and pump system at an intermediate location (elevation 2,964 feet), and a livestock water outlet structure with 1.5-inch HDPE pipe and automatic drain valve to prevent winter freeze damage. Construction details specify minimum burial depths of 6 feet to top of pipe, grade slopes of 1 percent minimum away from structures, and precise elevation specifications ranging from 2,941.35 to 2,964.00 feet. The document serves as the technical specification and construction blueprint for this water system project.
