ANNUAL REPORT OF SECRETARY MISSOURI RIVER COMMISSION, 1887-'88.

MISSOURI RIVER COMMISSION,
Saint Louis, Mo., June 30, 1888.

SIR: I have the honor to submit the following annual report of the work in charge of the secretary of this Commission, for the fiscal year ending June 30, 1888. Very respectfully, your obedient servant,'

Lieut. Col. CHARLES R. SUter,

Corps of Engineers, U. S. Army,

THEO. A. BINGHAM,

First Lieutenant of Engineers, Secretary.

President Missouri River Commission, Saint Louis, Mo.

SURVEYS.

Except a little precise leveling no work was done during the year.

The gap in triangulation still to be completed is from Fort Leavenworth, Kans., to Trovers Point, Mont., 1,520 miles.

The gap to be filled with permanent bench-marks is about 1,787.5 miles, there being tervals still incomplete between Waverly, Mo., and the mouth of the river of 267.5

miles.

The precise leveling, above referred to, was done to connect the elevations of the Missouri River permanent bench-marks with the Saint Louis City Directrix. Report to you of November 21, 1887, gives the results, and to it reference is respectfully ade. (Hereto appended, marked Appendix A 1.)

The list of Missouri River bench-marks, with their descriptiohs, elevations, etc., as revised, amended, and corrected to date, and an edition of 240 copies printed in May, 1888, at a cost of $0.67 per copy. It is hereto appended marked Appendix A 2. The fleet and plant used for surveys have been cared for on the Kansas City divis, being utilized for construction work when so needed.

PHYSICAL DATA.

The compilation of the data on file has been completed.

In addition to the regular ones, 11 monthly cross-sections of the river at the Bismarck, Dak., Bridge have been added to our files.

Work has been begun on the preparation for publication of the data of boring made in the Missouri River Valley under various auspices.

Tabulations were made of all high-water records on file for all gauges and bridges along the river; also of all known dates of ice closings and openings of the Missour River and of the Mississippi River at Saint Louis. (Hereto appended.)

Yearly gauge sheets for 1886 for twenty regular gauges, with their histories, etc. have been compiled. . Gauge records at Blair, Nebr., for 1882-1887, and at Rulo, Nebr. for 1883-1887 have been added to our files.

Current gauge hydrographs have been kept up to date.

[blocks in formation]

The study showed that mean discharge curves could not be relied on to determin discharge without more information as to the shifting of these curves on the gaug scale. So attention has been directed to a comprehensive collection of such data fro various sources.

An extended study of river profiles is in progress. By a combination of gauge-rea ings and slope data it is proposed to fill out profiles of mean high and mean low wate and to show profiles of extreme high waters and of bank elevations; also to show dur tion and height of high waters above mean high water. Such profiles will be neede in determining the high-water plane called for by letter from Chief of Enginee dated Washington, D. Č., April 25, 1888.

Mr. Jas. A. Seddon and Mr. R. F. Grady have rendered faithful and efficient ser ice in this department during the year.

For further details reference is respectfully made to Mr. Seddon's report, hereto a pended (marked Appendix A 3).

›n as funds are available it is the intention to put standard wire gauges on the g bridges: Sioux City (when completed), Nebraska City (when completed), andolph, and Sibley.

g to decrease in funds all the gauge observers were in March, 1888, put on , which was a hardship for them, as they are but poorly paid at best ($10 per the observer at the Saint Joseph bridge had to be discharged, and if a new iation is not available by August 1 all will have to be discharged. ot necessary for me to call your attention to the real calamity to all interests ed with the Missouri River which such a cessation of gauge-readings would spectfully urge upon the Commission that the appropriations for preservation rvation of gauges should be continuous, and not dependent each year on the n fate of a river and harbor bill. The importance of this system has been ted for the Mississippi River and should be extended to the Missouri River.

MISCELLANEOUS.

ying with letter from the Chief of Engineers, U. S. Army, of February 15, nap was made showing the location of all bridges across the Missouri River, line cross-sections of river and bridges (hereto appended). A table was also I giving the important dimensions and data relative to the bridges. Copies nished the Chief of Engineers and members of this Commission.

il, 1888, a 100-foot steel tape was compared with our 300-foot standard for int Carter, Corps of Engineers, U. S. Army, Savannah, Ga., his office bearing nse, viz, about $25.

ie a comparison under similar conditions was made of a 300-foot steel tape at est of Captain Quinn, Corps of Engineers, U. S. Army, Duluth, Minn. rence map of the Missouri River from Sioux City to the mouth, on a scale with all information on file in this office, has been nearly completed. The n is to lithograph this as soon as funds are available. The cost will be small, at $50 for 500 copies.

orders from the president of the Commission an inspection was made Janu888, of location, plans, progress, etc., of the Omaha and Council Bluffs Railmpany's bridge at Omaha. Report was submitted January 26, 1883. The the president of the Commission is given in Senate Ex. Doc. No. 83, Fiftieth 3, first session.

pection was also made under orders from the president of the Commission of on works on left bank of Missouri River at Winthrop, Mo., opposite Atchistructed by the railroads whose property was there endangered. Report was ed April 23, 1888.
