Steamboat Rock Dam Mitigation - Phase 1, Iowa River, Hardin County

This project involves the removal of the existing dam on the Iowa River at Steamboat Rock, with the goal of restoring natural river conditions through staged dam removal that allows for controlled sediment release. The scope includes constructing a series of stone structures to replace the dam, shaping and stabilizing the riverbanks, and installing various features such as a granular boat carry-down ramp (with an alternate option for a concrete ramp), tributary step-down structures, a granular footpath, and site restoration efforts. The work emphasizes environmental considerations and aims to enhance river habitat and recreational access. All project documents, including plans and specifications, are accessible through Beeline and Blue, with a scheduled bid closing date of July 24, 2025. The project is overseen by the Iowa Department of Natural Resources, with Heath Delzell serving as the project engineer. The contract is estimated to be between one and five million dollars, and interested bidders can obtain further information or submit proposals via the designated contact points, including the primary contact Darin Galbraith. The solicitation is open to qualified contractors, and the project emphasizes staged implementation to ensure environmental safety and effective river management.
