MISSOURI RIVER COMMISSION, OFFICE OF DIVISION ENGINEER, OFFICE BOAT MARGARET, Gasconade, Mo., June 30, 1894. COLONEL: I have the honor to submit the following report of the operations under my charge, on the Kansas City division of the Missouri River, for the fiscal year ending June 30, 1894. Work on this division was confined to the loading of plant and construction materials on barges at East Bottoms, near Kansas City, and the care of plant while awaiting transportation from that point to Gasconade, Mo. On July 1, 1893, there were 28 hulls at East Bottoms. These were taken away in tow by the steamer Gasconade and the United States tow boat Alert; the former taking 7 hulls in 2 tows on July 4 and 12, respectively; the latter took 21 hulls in 3 tows, leaving East Bottoms July 6, 17, and 24. The expense of all of the above operations was charged to the allotment for systematic improvement in first reach. Very respectfully, your obedient servant, Lieut. Col. CHARLES R. SUTER, Corps of Engineers, U. S. A., President Missouri River Commission. S. WATERS FOX, APPENDIX E. ANNUAL REPORT OF SAMUEL H. YONGE, DIVISION ENGINEER, OSAGE DIVISION, 1894. MISSOURI RIVER COMMISSION, OFFICE OF DIVISION ENGINEER, COLONEL: I have the honor to submit my report of the operations conducted under my charge on the work of improving the Missouri River on Osage division of first reach during the fiscal year ending June 30, 1894, as follows: SYSTEMATIC IMPROVEMENT IN THE FIRST REACH. Projects. The construction of improvement works was, with one exception, viz, Dike 21A, carried on under approved projects fully described in former reports. The several works, and the projects of which they form parts, are as follows, viz: The construction of incomplete parts of Dikes B and C of the project of February 9, 1892; the extension of Dikes 17Â, 18A, and 19A, under project of February 17, 1892, as amended in project of March 21, 1893; the completion of Dikes 20 and 21 to the lines of rectification as fixed by the latter project; the construction of Dike 34, and of parts of Dikes 26, 27, 28, 29, 35, and 36 also of the latter project. The construction of Dike 21A became necessary to meet a change in the direction of flow on the Barkersville crossing, caused by the formation of a reef whereby Dike 22 was threatened with being flanked. Your verbal approval for its construction was given July 28, 1893. After the river had fallen sufficiently to observe the effects of Dikes B, C, and D of the Cedar City group, it became apparent that these dikes alone were not sufficient to entirely prevent a flow into Cedar City Chute, to accomplish which at least one more dike would be required. In pursuance of your instructions, a survey and examination of the river in that vicinity were made in July, on which a report was submitted recommending a modification of the project of February 9, 1892, by changing the proposed location of Dike E so as to make it normal to the general direction of flow from the main river into the chute (see Pl. 1). Your approval of the above recommendations was given in August, and I was at the same time instructed to proceed with the work when it should become possible to do so. It was not possible, however, to construct the dike during the summer and fall of 1893, on account of all the available plant being required for more urgent works, nor in the spring of 1891, on account of there being no funds available for the purpose. By your letter of August 29. 1893, I was directed to proceed with the work of extending the Murrays Bend revetment of 1892 to the foot of the bend, in accordance with the approved project of August 19, 1892. In the early part of September I received your verbal instructions to proceed with the construction of the low-water dam, between the Osage and Missouri rivers, at the head of Dodds Island, proposed in the project of March 22, 1893. Two projects with estimates of cost and extent of work required for extending the improvement of the Missouri River from the head of Isbell section to Portland, Mo., were submitted in compliance with your verbal instructions, under date of December 19, 1893. DIKE CONSTRUCTION. During the summer and fall seasons dike construction was carried on at 15 dikes. Two parties were engaged in the work-the first being employed from July 6 to September 30, the second from July 21 to November 19. Preparations for resuming dike work were made in April and a party sent out May 2 to complete the pile driving and bracing as far as practicable. Field operations were suspended May 30, on account of the funds allotted for spring work being expended. During the above periods the equivalent in 3-row dike of 1, 2, 3, and 4 row dike completed amounted to 10,218 linear feet. The foot mat for 1,045 linear feet of dike was also woven and ballasted and several dikes repaired. This comprised all the dike work, whose construction had been approved, that could be reached by the plant. The details of some of the dikes constructed differ from those used formerly, as follows, viz: Cypress piles used instead of native oak; white oak piles employed for 200 feet, instead of 100 feet, at the stream end; the length of bent increased to 10 feet; the dimensions of the longitudinal and transverse braces increased; the top diagonals omitted; long-leaf yellow pine used for braces instead of the short-leaf variety, and three-fourth inch round iron screw bolts substituted for the five-eighth inch square drift bolts. The details of bracing are shown on Pl. ii. The dikes constructed with the above changes are 26, 27, 28, 29, 34, 35, 36, and the outer part of 19 A. Dike B. At the close of the last fiscal year, 368 feet of Dike B had not been completed on account of the stage of water not having been high enough to give sufficient depth for the floating plant on that length of dike. Advantage was taken of a temporary high stage between July 6 and 13 to connect the dike with the bank by completing 175 feet. The remaining 193 feet, however, were not completed on account of being inaccessible. Dike C.-During the temporary high stage mentioned above Dike C was completed by constructing 75 feet at its shore end. Dike 20.-After proceeding with work at B and C as far as it was practicable, the party was moved to Dike 20, where pile-driving with a steam hammer was begun July 14. The dike was extended 497 feet to the line of rectification and a wing 50 feet long constructed under the stream end. Pile-driving was completed on the 22d, and the dike entirely completed August 3. White-oak piles were used for the outer 200 feet and wing, and native-oak piles for the remainder of the dike. Dike 21.-Pile-driving on the extension of Dike 21 was begun with a steam hammer July 24 and completed July 30. The dike was extended 206 feet to the line of rectification. On account of the scour that had taken place at the outer end of the work after operations were suspended last year the depth of water was too great to make a direct connection between the old and the new work, and the extension had to be begun 90 feet back from the end of the former and 80 feet above it, involving the construction of 306 feet of 3-row dike and 97 feet of 2-row dike, 47 feet of the latter being the connection between the old and the new work and 50 feet wing. The work was carried on under considerable difficulties on account of the deep water and the strong current in which the dike had to be constructed. The dike, however, was successfully completed without accident, excepting a collision between the packet 4. L. Mason and the plant. This accident was probably unavoidable, as the outer end of the dike where the plant was employed was directly in the channel, which was very close and crooked. The damage done was inconsequential. Dike 21 d. The effect of the dikes constructed immediately above Barkersville and those opposite them in 1892 and 1893 was to concentrate the flow and cause it to wash away the head of the middle bar opposite Barkersville, the crossing moving down stream as the bar cut away; also to fill up to a certain extent the old channel along the north bank in that locality. The effect of the dikes in causing the bar to cut away became in a measure spent opposite Dike 20, and the volume of flow divided about equally in two parts on the head of the bar below, one part flowing into Osage Chute, the other into the old channel between dikes 21 and 22. The right side of the bar gradually extended and the flow in the old channel was forced by that across the head of the bar against the dikes, by which action the suspension of navigation in this chute was for a time threatened. The change in position of the bar described above is shown on Pl. III, from which it appears that during the period of about one year the head of the bar moved downstream about 3,000 feet. Work on Dike 21 A was begun August 1. It could not be carried to the line of rectification, as it would have crossed the steamboat channel, thereby closing navigation, nor connected with the main bank on account of a wide foreshore. The part constructed consisted of 136 linear feet of ballasted foot mat between the main bank and the water's edge, 183 feet of 2-row dike, and 167 feet of 3-row dike with a short wing. The difficulties of constructing the dike on account of the current were greater than ever before experienced on this work and the progress made was slow. Work was suspended August 17, the dike having been carried as far as it was then practicable. The work remaining to complete the dike consists of driving and bracing piles for 136 feet at the shore end and extending the dike to the line of rectification, a distance of 450 feet. Dike 17 A.-The invariable heavy scour that occurs at the stream end of dikes projecting into the current on the concave side of bends made it necessary in extending this dike to place the new work 60 feet above the old and make it lap 40 feet. The dike was extended 73 feet to the line of rectification. The actual length of dike constructed was 113 feet of 3-row and 93 feet of 2-row, 50 feet of the latter being wing. Pile-driving with a steam hammer was begun August 7 and completed August 12. The extension was entirely completed and the screening on the old work repaired by August 29. Cypress piles were used for the connection between the old and the new work, native oak for the first 60 feet of the extension, and white oak for the outer 53 feet and wing. Dike 18 A.-As described in my last annual report, the work of extending Dike 18 A in accordance with the project of March 21, 1893, was attempted in May, 1893, by constructing a part of the usual 2-row dike for connecting the old work with the proposed extension. Before very much was accomplished work had to be suspended on account of the river rising over the dike. Work on the dike was resumed August 18, the part of the dike constructed in May repaired, and the dike extended. It laps the old work 70 feet, is situated 100 feet above it, and has a 43-foot wing. The length of the 3-row dike in the extension is 313 feet, 70 feet of which is lap. White-oak piles were used for the outer 150 feet and wing, and cypress for the remainder of the work. The dike was completed September 1. Dike 19 A.-This dike extends 1,471 feet from the main bank. It consisted of 1,890 feet of 3-row and 271 feet of 2-row dike, the latter being wings and the connections between the old and the new work where offsets were made. The discrepancy in length between the 3-row dike constructed and that of the dike's axis is accounted for by laps at offsets, amounting to 174 feet, and dike destroyed during floods, amounting to 245 feet. At the close of the last fiscal year the dike had been extended 1,100 feet from the shore, or to within 580 feet of the line of rectification. Work on it was resumed August 12, 50 feet above and 68 feet back from the end of the old work. Good progress was made until August 19, when a sharp rise occurred. The rise brought considerable driftwood which lodged under and around the plant and among the piles, bending over and breaking off a number of the latter. By the 20th the river had risen to the top of the piles, making it necessary to move the plant from the dike for safety. The rise caused a suspension of work for five days, and the tangled mass of driftwood and piling made another offset in the dike necessary. The dike was completed September 13. With the exception of the outer 150 feet, for which white-oak piles were employed, large cypress piles were used for its construction. On account of the exposed position of the outer end of this dike to ice and driftwood a short wing was constructed above it in addition to the usual wing below. All of the piles were driven by steam hanımers to penetrations of from 21 to 25 feet. During a rise in April a field of driftwood accumulated above the dike. Shortly before the outer end was submerged by the rise the whole structure appeared to be in excellent condition. After the water fell it was discovered that the outer 207 feet had been entirely swept away. Soundings made subsequently on the line of the dike point to excessive scour as the probable cause of this occurrence. Dike 26.-Jet pile-sinking was begun at dike 26 August 1, 727 feet from shore, shallow water preventing the pile-sinkers being operated any closer to the bank. By August 19 the dike had been carried to within 1,058 feet of the line of rectification, where a short wing was constructed and work suspended, as a further extension would have obstructed the steamboat channel. In the latter part of August the bar near the shore cut away and made it possible to sink piles in the gap at the shore end for 173 feet. In the latter part of September and early part of October the foot mat was constructed across the gap to the high bank and ballasted. Ir May the piles were driven and braced for a distance of 151 feet at the north end of the gap. The remainder of the gap could not be constructed, as the low stage of water made it inaccessible to the plant. There still remains to complete the dike, to extend it 1,013 feet at the stream end and to construct 405 feet in the gap. Cypress piles were used exclusively for this dike. Dike 27.-Work at dike 27 was begun July 22. As at that time the steamboat channel was situated close to the bank and crossed the proposed site of the dike, it was not feasible to carry the dike farther than 245 feet from the shore. This point was reached with the pile-driving August 2. Considerable difficulty was experienced during construction from the swift current. On August 4 a drift log struck and broke five three-eighths-inch steel cables supporting the foot mat, which was under construction. This allowed the mat to be rolled up by the current against the piles, resulting in the outer four bents being overturned. Subsequently this part of the dike was reconstructed and a wing placed under the end. Dike 28.-The construction of dike 28 was begun July 27. The dike was completed for a length of 1,316 feet from the shore end September 30. This was as far as it was possible to carry the work without obstructing the steamboat channel. Cypress piles were used exclusively for this dike. About one-third of the piles were driven by a steam hammer and the remainder sunk by the water jet. In jet pile sinking, proper penetrations could not be given with the 1-inch nozzle heretofore employed. Satisfactory results, however, were obtained by using two three-fourths-inch nozzles, one of which was fastened to the foot of the pile and the other moved up and down its side during the sinking. The difficulty in sinking piles with a single jet appeared to be caused in a measure by the light weight and buoyancy of the cypress, oak piles in the same locality being given good penetrations by one jet of the larger size. The shore end of the dike for a distance of 186 feet was double braced on account of its height. The dike has still to be extended 874 feet to reach the line of rectification. Dike 29.—Pile sinking was begun August 17 at a point 1,640 feet from the shore end of the dike, it not being practicable at that time to get the plant nearer shore on account of sand bars and shallow water. By September 9, 190 feet of the dike next to shore and 903 feet at the outer end were completed, leaving a gap of 1,172 feet, on which it had been only possible to construct and ballast the foot mat. Work was resumed on this dike May 9, and the pile-driving and bracing constructed for 357 feet at the south end of the gap and 312 feet at the north end. The remaining 503 feet in the gap could not be constructed on account of the bar, which it crosses, being above water. The dike has also to be extended 210 feet. Dike 34.-Dike 34 is 1,065 feet long and extends to the line of rectification. Its construction was begun September 2. It was not possible at that time to connect the dike with the bank on account of a foreshore of 120 feet, across which, however, the foot mat was laid and carried up the bank to S. H. W. The dike was completed, with the exception noted above, to the line of rectification September 30. Three hundred feet of the pile structure, beginning 190 feet from the shore end, being high, was double braced. As this dike is the head of a group and will be greatly exposed to running drift and ice, the largest piles were selected for its construction. White-oak piles were used for 200 feet at the stream end and the wing, and native oak for the rest of the dike. Most of the piles were placed with the jet. The penetrations obtained by this method in some instances not being satisfactory, a steam hammer was subsequently employed to complete driving the piles down. During a rise in the early part of March a great quantity of driftwood collected above the dike, which resulted in a breach of about 140 feet being made near the shore end. From soundings made in the breach in April, it appeared that a scour of from 12 to 16 feet had occurred and that the mattress had settled to the bottom. By this scour the penetration of the piles was reduced to less than 10 feet, making the unsupported lengths of the piles above ground from 26 to 30 feet. Work was resumed on this dike May 2. The breach was repaired and the shore end of the dike constructed. The original design for this dike was a 3-row structure. On account of the increased depth from scour, the reconstructed part across the breach and the part standing between it and the shore were made 4-row dike, and the largest and longest piles available used for the work. These piles were driven with a steam hammer and given penetrations of from 22 to 31 feet. The driving was very hard. A rise in the river, which occurred before the work was entirely completed, made it impossible to attach all the bracing. Dike 35.-Construction on dike 35 was begun September 4 and suspended September 30. As at this time and during the remainder of the fall the width of the waterway at the dike was only equal to its proposed length, it was not practicable to extend the dike farther than 896 feet from its shore end." |
