In northeastern Iowa, on Dry Run, a tributary of the upper Iowa River at Decorah, Iowa. (See U. S. Geological Survey map, Decorah quadrangle, Iowa.) Existing project. The Flood Control Act approved June 22, 1936, authorized a flood-retention reservoir and channel enlarge ment downstream for the protection of the city of Decorah. The Flood Control Act approved August 18, 1941, Public No. 228, Seventy-seventh Congress, first session, modified the project to provide for diversion of Dry Run into the upper Iowa River, a levee system along the upper Iowa River in Decorah for protection of adjacent property against augmented high-water flow, raising a section of railroad tracks and State Highway No. 9, and necessary alterations to bridges and protection to existing structures in the vicinity. The diversion is to be accomplished by a dam across Dry Run at a point about 1 mile southwest of Decorah and a diversion channel 3,200 feet in length from that point through high ground to the upper Iowa River on the north. The project will provide complete protection to residential, industrial, and commercial areas totaling about 260 acres within the city limits of Decorah against the maximum probable flood on Dry Run and the upper Iowa River. Floods creating serious damages have occurred about once every 11 years. The estimated Federal cost is $460,000, and the cost to local interests for lands and damages is $22,000. Local cooperation.-See page 5 for requirements. Operations and results during fiscal year.-Design, including preliminary surveys and explorations, was intermittently carried on by hired labor as other work more essential to the war effort permitted. The costs for the year were $25,852,43 for new work, and the expenditures were $25,767.43. Condition at end of fiscal year.-Design, including preliminary surveys and explorations, is approximately 96 percent complete. No construction has been started. The total costs under the existing project to June 30, 1945, were $74,018.03, and the expenditures were $71,747.82. Proposed operations.-Of the balance unexpended June 30 1945, $5,752.18, the amount of $3,481.97 will be applied to new work, completing design of proposed improvements with hired labor, and $2,270.21 for liquidation of accounts payable. The additional sum of $382,500 can be profitably expended dur ing the fiscal years 1946 or 1947 for construction of the project by contract. alance unexpended July 1, 1944 mount allotted from War Department Civil Appropriation Act approved Apr. 28, 1942 mount allotted from War Department Civil Appropriation Act approved Mar. 31, 1945 Amount to be accounted for ross amount expended 382, 500.00 Balance unexpended June 30, 1945 Outstanding liabilities June 30, 1945 Balance available June 30, 1945 Amount (estimated) required to be appropriated for completion of existing project1 Amount that can be profitably expended in fiscal years 1946 or 1947, for new work' 1 Exclusive of available funds. 382, 500.00 10. LAKE TRAVERSE AND BOIS DE SIOUX RIVER, S. DAK. AND MINN. Location. The works covered by this project lie along Lake Traverse and Bois de Sioux River between the upper end of Lake Traverse at Browns Valley, Minn., and the mouth of Bois de Sioux River at Breckenridge, Minn. The lake drains through the river to the Red River of the North, and the two waters form a portion of the boundary between the State of Minnesota and the States of North and South Dakota. For general location see United States Geological Survey map of Minnesota. Existing project. The plan of improvement provides for use of Lake Traverse as a flood-control and water-conservation reservoir and for channel improvement in the river below the lake. It includes construction of a dam near White Rock, S. Dak., at the north end of Lake Traverse, a structure at the Reservation Highway crossing for control of the upper section of the Reservoir, levees, and embankments necessary near Browns Valley, Minn.,, and channel improvement of approximately 24 miles of the Bois de Sioux River from the outlet of Lake Traverse northward toward Breckenridge, Minn. The dam near White Rock, S. Dak.. consists of a movable-gate control section between two sections of rolled fill embankment with a total length of approximately 14,400 feet from high ground on the Minnesota side to high ground on the South Dakota side, and supplemented by channel improvement of the Bois de Sioux River downstream and an embankment approximately 5,000 feet long at the south end of Lake Traverse for the |
