About this file

Written by GovTribe AI · Jul 30, 2025

The document is a comprehensive set of engineering plans for the Bonneville Lock and Dam Bradford Island Fish Ladder Exit Dredging project for Fiscal Year 2025, prepared by the U.S. Army Corps of Engineers Portland District. The plans detail a dredging and rock removal project focusing on two primary acceptance areas within the fish ladder exit, with specific elevation requirements and constraints. The project involves removing sediment and rock from designated zones while maintaining a 6-8 foot minimum pool depth, with a 6-inch concrete apron at the 7-foot minimum pool level that must not be dredged.

The technical drawings provide detailed geospatial information, including hydrosurvey data from February 2025, site maps, and cross-sectional views of the project area located on Bradford Island in the Columbia River. The plans include specific technical specifications for dredging, milfoil removal, and rock extraction from various bays of the spillway, with careful attention to existing infrastructure like continuous baffle blocks and the dam's structural elements. The solicitation number W9127N25BA011 is consistently referenced across the documentation, indicating this is a formal federal contract opportunity for specialized marine engineering work at the Bonneville Lock and Dam facility.

Horizontal Coordinate System:

North American Datum of 1983 (NAD83 (2011)), projected to the State Plane Coordinate System (SPCS), Oregon North Zone. Distance units in U.S. Survey Feet.

Vertical Datum:

Soundings and depths upriver of the dam are shown in feet and are below a datum plane which is 70.0 feet (Minimum Pool Elevation) above National Geodetic Vertical Datum of 1929 (NGVD29) and 73.3 feet above North American Vertical Datum of 1988 (NAVD88).

River mileage conforms to the River Mile Index of the Hydrology and Hydraulics Committee, Pacific Northwest River Basins Commission, July 1972.

The information depicted on this map represents the results of a survey conducted on the date indicated and can only be considered to represent the general condition existing at that time.

Riprap slopes within the dredge prism are excluded from the required dredge depth as the riprap makes this unattainable.
