Specifications include, but are not limited to: Provide construction drawings that will eliminate the dangerous hydraulic at all flow ranges. Provide construction drawings that will improve upstream passage of native fish at all flow ranges. Provide construction drawings that will improve upstream passage of native fish at all flow ranges. Provide construction drawings that will stabilize surrounding banks within the vicinity of the project area with improved public access. Provide construction drawings that will provide habitat with associated informal access areas to reduce impacts to existing angling opportunities at the dam. Iowa DNR has developed initial project type due to the constraint of water elevations upstream of the dam. Iowa DNR is open to alternative design types as long as the design meets the requirements of impoundment elevations and fish passage. Design should strive to reduce long-range costs with self-maintaining river channel while avoiding negative effects on other infrastructure (bridges, levees, etc.). Provide construction drawings that will enhance river navigation (in this area, primary uses are recreational paddle craft).
