standard specifications for construction work were used. Location, quantities and costs of open river regulating works follow:

1 Includes cost of screening 2,640 linear feet of dikes with mattress lumber.

New work.-Six dikes, totaling 1,520 feet in length, were built by hired labor with Government plant, at a cost of $70,127.53. Work for one revetment, consisting only of grading 1,200 cubic yards of material by hired labor with Government plant, was accomplished at a cost of $153.25, and 241,797 cubic yards of material were handled by two United States hydraulic dredges in preparing one locality for new regulating works at a cost of $35,743.25. Nineteen dikes, totaling 7,835 feet in length, were built under contract at a cost of $471,626.57. Two revetments, totaling 2,155 feet in length, consisting of 2,155 squares of mattress and 584 squares of paving, were built under contract at a cost of $65,987.28. In addition to complete work there was under construction, by contract, 1 revetment to total about 1,160 linear feet and 10 dikes, totaling about 5,645 linear feet. The total cost of new work was $643,637.88, from regular funds.

Maintenance.-Dikes and revetments were repaired at a cost of $400,806.49. The required 9-foot channel was maintained, except for the short periods needed to move a dredge to the shoal, by three United States hydraulic dredges. During the year 46 shoals developed, of which 43 were dredged once, and 2 were dredged twice. There were 4,824,627 cubic yards of sand and gravel removed by these dredges from the channel through 46 bars; 217,173 cubic yards of material were removed in outside-the-channel dredging at a cost of $30,840.27. The channels had a combined length of 19 miles, an average width of 310 feet, and an average gain in depth of 5.9 feet. The total cost of maintenance dredging was $440,223.35.

Hydrographic surveys were made covering approximately 105 miles of river, costing $36,943.85. Other miscellaneous costs were: Snagging, $15,837.42; aids to navigation, $21,836.16; gages, $15,565.61; cooperative stream gaging, $6,981.87; safeguarding structures, $39,394.15; and releasing grounded vessels, $598.64, all charged to maintenance. The total cost of all maintenance was $978,187.54. The expenditures were $1,749,137.27 from regular funds.

Condition at end of fiscal year.-Work under this project is about 70 percent complete. The quantities required to complete the project are estimated at 45 dikes, 49,000 linear feet; 28 revetments, 108,000 linear feet, and the canal, lock, and levees at Chain of Rocks as recommended in House Document No. 231. Dikes and revetments are now in good repair and the channel has been greatly improved by the work that has been done. Dredging is required at low stages to remove temporary shoals and maintain the required channel depths.

In recent years, the project dimensions of channels have generally been maintained throughout the navigation season. The navigation season formerly extended from the middle of February to the middle of December, the river being generally closed by ice the remainder of the year. However, in recent years navigation has continued throughout the winter, except when the river is actually blocked by running ice or gorges. The river is generally above the 10-foot stage, St. Louis gage, for 6 months of the year, latter part of February to latter part of August, during which time project channel depths generally prevail without dredging. The mean stage of the river for the fiscal year 1944 was 12.13 feet, St. Louis gage. The mean stage of the river for the fiscal year 1945 was 13.25 feet.

The following table gives condition of the channel during the fiscal year 1945:

The costs and expenditures under the existing project to June 30, 1945, have been as follows:
