About this file
These are detailed engineering design drawings for the Finale Detention Dam Reconstruction project located in Valley County, Montana. The 16-page PDF document contains comprehensive technical plans prepared by DOWL, dated December 20, 2024, for the Bureau of Land Management (BLM). The drawings cover multiple technical aspects of the dam reconstruction, including dam embankment plans, outlet works design, spillway improvements, site excavation profiles, access road details, and topographical mapping. Key design elements include removing existing structures, constructing new outlet works with concrete riser and conduit, creating a low-level outlet works inlet structure, installing grouted riprap stilling basin, establishing a new auxiliary spillway, and implementing gravel road surfacing on the dam crest. The drawings provide precise engineering specifications, elevation profiles, material specifications, and detailed cross-sectional views of the proposed dam reconstruction project.
