About this file

These are detailed engineering drawings for the Finale Detention Dam Reconstruction project located in Valley County, Montana, prepared by DOWL for the Bureau of Land Management (BLM). The 16-sheet technical drawing set, dated December 20, 2024, provides comprehensive design specifications for dam reconstruction, including site plans, excavation details, embankment sections, outlet works, low-level outlet structures, spillway improvements, and access road configurations.

The drawings cover multiple technical aspects such as dam crest details, outlet works tower and conduit designs, filter sand blankets, riprap stilling basin layouts, and geotechnical cross-sections. Key components include a new outlet works tower, conduit systems (30" RCP and 12" PVC), embankment modifications, gravel road surfaces, and precise elevation and coordinate information. The project area is situated approximately 41.5 miles southwest of Glasgow, Montana, with the design integrating existing ground surfaces and incorporating infrastructure improvements across multiple station points and elevation grades.
