About this file
The document is a set of preliminary engineering plans for the Underhill Fishway project by the Oregon Department of Fish and Wildlife, located on Fifteen Mile Creek in Wasco County. The project involves creating a new fishway with associated access and staging areas, with a total construction zone of approximately 3,119 square feet. The plans include two primary sheets: a cultural resources area of potential effect (APE) site plan and a detailed work zone excavation plan. The existing dam and fishway will remain in place, along with an old ditch headgate.
The excavation plan shows a color-coded depth analysis of the proposed work zone, with excavation depths ranging from 2 to 9 feet. The project appears to be in the preliminary permit review stage, as indicated by the document watermark, with a date of 8/26/2025. The site plan reveals two access and staging areas of approximately 22,252 and 10,418 square feet, respectively, and includes existing structures, fence lines, and topographical contour lines. The project seems focused on fish passage improvements, consistent with the Oregon Department of Fish and Wildlife's Fish Screening and Passage Program.
