About this file

Written by GovTribe AI · Apr 17, 2025

These engineering drawings detail the reconstruction of the Melstone Dam, located in Musselshell County, Montana, for the Bureau of Land Management. The comprehensive set of 27 technical drawings covers multiple aspects of the dam reconstruction project, including site plans, embankment sections, outlet works, spillway modifications, access roads, and structural details. Key components include a new outlet works tower, inlet and outlet structures, toe drain systems, riprap stilling basin, and modifications to the existing dam infrastructure.

The drawings provide extensive technical specifications for the reconstruction, featuring detailed cross-sections showing excavation limits, embankment construction, geotextile fabric placement, sand filter blankets, and gravel road surfacing. The project involves removing existing outlet pipes and structures, constructing new conduits with 30" and 18" pipes, installing a new gate system, and reshaping the dam's embankment with careful attention to slope protection, drainage, and structural integrity. The design incorporates elements like a conical trash rack, gate stem encasement, and precise elevation measurements to ensure a comprehensive reconstruction of the Melstone Dam.

BASIS OF SURVEY

THIS PROJECT WAS SURVEYED ON THE MONTANA STATE PLANE ZONE 2500 COORDINATE SYSTEM USING RTK GPS. THE PROJECT WAS BROUGHT TO GROUND AT SURVEY CONTROL POINT CP-1. THE GEODETIC DATUM IS NAD83(CONUS). THE VERTICAL DATUM IS NAVD88 (GEOID18). HORIZONTAL UNITS ARE INTERNATIONAL FEET. VERTICAL UNITS ARE US SURVEY FEET. DATE OF FIELD SURVEY WAS 10/18/2023.

PROJECT CONTROL WAS ESTABLISHED BY OPUS REPORT FOR CONTROL POINT CP-1.

VALUES FOR POINTS 2-4 WERE DETERMINED BY REDUNDANT RTK GPS OBSERVATIONS FROM POINT 1.
