ANNUAL REPORT OF MR. 8. WATERS FOX, DIVISION ENGINEER, gasconade DIVISION. MISSOURI RIVER COMMISSION, OFFICE OF DIVISION ENGINEER, COLONEL: I have the honor to submit herewith a report of the operations under my charge on the Gasconade Division of the Missouri River for the fiscal year ending June 30, 1897. The following illustrations accompany: A map (Pl. I) of the river from Isbell Station to Rhineland, as developed from a survey made last fall, showing proposed rectification of shore lines and location and character of improvement works completed, in process of construction, and proposed; also cross sections of the river at intervals of about 1,000 feet, and steamboat channels. Seventeen plates (Pls. II to XVIII) showing in superimposition low stage cross sections of the river reduced to standard low water, with a view to illustrating progress made toward rectification. Six photographic views (Pls. XIX to XXIV) showing dike construction parties at work and completed dikes. Six photographic views (Pls. XXV to XXX) showing a bank-head in various stages of construction and after completion. Six plates (Pls. XXXI to XXXVI) illustrating, by means of dry and wet contours and float paths and velocities, characteristic features of accretions and bottom, as well as currents, that obtain in Missouri River from permeable dikes. Three plates (Pls. XXXVII to XXXIX) illustrating, by means of contours and float paths and velocities, the conditions of flow in Chamois Reach prior to the growth of accretion above Dike 28 A', and the commencement of the construction of the bankhead and after. One plate (Pl. XL) showing in superimposition a series of partial cross sections inside and outside of outer wall of bank-head, covering a period beginning three days prior to commencement of work on the structure and extending some seventyone days after it had been practically completed. One plate (Pl. XLI) showing the plan followed in constructing the bank-head. The operations of the year comprised revetment and dike construction, as well as the repairing of both kinds of work; the construction of an experimental bank-head, designed as a substitute for revetment; the care and repair of plant; surveying; the preparation of projects and maps, with estimates of cost; examinations and special reports on conditions at several points outside of first 1each, and miscellaneous incidental work. The work was done under an allotment of $164,000 for continuing the systematic improvement in first reach and in accordance with my project of July 13, 1896, as revised from time to time by yourself. The total expenditure during the year was $116,133.14, as shown in Appendix, Exhibit I. REVETMENT. Heckmann Island No. 3 (see Pl. I, K', L').—The earliest and all subsequent projects for the improvement of the Straubs Bend reach contemplated the protection of the south bank of this island by a revetment which should extend around the head of the island and well into Boatwrights Chute, but because of the postponement from time to time of the construction of the group of dikes against Miller Island and the final abandonment of that feature of the original scheme of rectification, the necessity for this work did not sooner develop, or at least it was suffered to wait on more urgent demands. The pool developed by the Bluffton group of dikes finally extended so far down that the closing of Boatwrights Chute (by the extension of Dike XV, and thus incidentally farther extending the pool) and protection of the island became at once necessary. A small party was put to work on August 6 clearing the bank of timber and undergrowth. Mattress weaving was commenced with one party August 12 and completed September 1. A second party was in service from August 20 to 28. In all, 2,725 linear feet, or 250,674 square feet, of mattress was woven, including one lap. The bank grading followed the weaving, but the trenches for dead-men anchorage were cut in advance with a jet supplied by hydraulic grader. The latter work was commenced August 6, the former six days later. Grading was completed September 24. Two thousand three hundred and twenty-five linear feet of bank, containing 7,530 cubic yards of earth, was graded to an average slope of 1 on 3. The distribution of ballast on mattress and upper bank commenced on August 21 and was completed September 24. The total quantity of rock ballast expended on the revetment was 7,677.2 cubic yards, an average of 2.87 cubic yards per linear foot. The cost of the revetment, as shown in detail in Appendix, Exhibit A, was $16,960.32, or $6.34 per linear foot. REVETMENT REPAIRS. The only expense incurred on account of the other revetments on this division was for the maintenance rather than repair of the Chamois Bend revetment. One hundred and ninety-eight dollars and fifty-eight cents was expended in placing 220 cubic yards of quarry chips on two bare spots on the mattress of that work in the locality of 8,500 feet below its head. The aggregate length of revetment now on the Gasconade division (23 miles of river) is 47,003 linear feet, or 8.9 miles. It is all now in excellent condition. The total cost of the work was $317,941.61, an average of $6.53 per linear foot. The total cost for repairs and maintenance to date is $5,712.82. Some of the work is now four years old, but the major portion of it a little more than two years. DIKE WORK. There were only two entirely new dikes built during the year-dikes XI A and XI B, in the middle section of Chamois Bend. These two and a third-Dike XI Clower down were originally projected to fair up that part of the bend, with revetment above and below, but it was subsequently decided to omit them and revet the bank, making that work continuous. Since the construction of the revetment the thalweg has taken the shape and laid in close to the shore of this bay, and there has been a middle ground in the next lower bay, but until recently, when the bar growth above Dike XXVIII A' had practically stopped the cross current resulting from longitudinal flow on the upper side of that dike, the development of the left-hand waterway was to some extent held in check. Now a marked crossing has been effected, but with a middle ground still in the bay below; a chute of considerable size has developed to the north of the towhead and the head and south bank of the latter, which has been uncovered by the washing away of the shore bar, is now rapidly yielding to the main flow of the river. It was to correct or ameliorate these conditions that the two dikes referred to were built. Other dike work consisted in extensions, repairs, and alterations of old work. Dike XI A.-Work on this dike was commenced on June 14 and practically completed June 27. The structure is 240 feet long; the first four bents are two-row and the others three-row work. The piles in the upper row of the other eight bents were reinforced by ten extra piles. The mattress of the revetment was utilized as a foot mattress for the dike as far as the eleventh bent from the shore; from that point a new mattress was made, 30 feet wide above the upper row of piles for four bents and 40 feet from there out a distance 40 feet beyond the end of the dike. The bracing consisted of a single string of 6 by 8 inch long-leaved pine wales fastened with seven-eighths inch screw bolts to the piles in each row near the top and on the upstream side; a direct brace for each bent, made of two pieces of long-leaved pine, 3 by 8 inches, placed so as to embrace all the piles in the bents and fastened to them with three-fourths inch screw bolts; these braces rested on the wales and were gained on them 1 inch to aid the bolt in transmitting a thrust; a tie, formed of two parts of three-fourths inch or four parts of three-eighths inch galvanized strand was put on each bent, extending from the pile in the upper row at the point where it entered the bottom of the river to the top of the pile in the lower row. Instead of the trail or dike head previously used and described in reports, two clusters of three piles each were driven midway between the outer two bents, one cluster 20 feet above the upper row of piles, the other 20 feet below the lower row. The clusters were braced to the dike with 6 by 8 inch timbers. Dike XI B.-Work on this dike was commenced on June 11, and was nearing completion when an accident occurred that practically stopped further progress. At the time, the night of June 24, the status of the work was as follows, viz, all of the piles, 109 in number, had been driven; the foot mattress woven to bent 37 (being 280 linear feet, or 21,910 square feet) was still afloat; bracing was completed to bent 20, except for fastening strand ties between bents 9 and 20, and wales only had been put on to bent 22. From the bank out the first 12 bents, or 110 linear feet, was two-row work, the balance, 26 bents, three-row. The revetment mattress was utilized as far out as the ninth bent from the shore; from there out a new mat was made, 30 feet wide above the upper row to bent 28, and then 40 feet wide to a point 20 feet beyond the outer end of the dike. The same system of bracing was used on this structure as on dike XI A. During a storm on the night of June 24, referred to above, an empty 100-foot barge that was moored to the outer end of dike XI A was blown adrift and down onto dike XI B, striking the anchor piles nearly broadside; three of them were broken off, thus allowing the foot mattress, which was anchored to them to buckle down against the dike, with the result that 11 bents, or 33 piles, in the dike, and the greater part of the included foot mattress was taken out. The remaining foot mattress was sunk and a driver put to work to close the breach. Nine dike and 27 anchor piles had been driven when a sudden rise in the river caused a suspension of operations on the 28th. The cost of these dikes is shown in detail in the Appendik, Exhibit B. Dike XXXII.-The construction of this dike was begun in March, 1896, and twice suspended, the last time on May 18, 1896, on account of high water. It was designed as a four-row dike, 660 feet long with a head 100 feet long. At the time of the last suspension 200 feet of it had been completed, and nearly all the piling had been driven, but no foot mat had been placed nor bracing put on the remaining portion. With the exception of 13 piles which had been carried away during the flood, the dike was in the same condition when work was resumed on the 10th of August. The work, which was completed 16 days later, consisted in driving 8 piles, weaving 563 linear feet, or 39,300 square feet, of foot mattress, and ballasting the same with 500 cubic yards of rock, in bracing 47 bents and curtaining 420 linear feet of dike. The system of bracing used on this dike was that commonly practiced on the division up to that time, the specifications for which were published in last year's report. An innovation was introduced in screening this dike. By your direction the practice which had prevailed of gradually opening up the screen (increasing mesh area) from the bank out was made more marked by omitting the screen entirely from the outer 5 bents, and then in the next 5 bents putting in 1 pole in the first, 2 in the next, 3 in the next, and so on to the fifth bent, from there inshore more rapidly increasing to a condition of juxtaposition in the shore bent. Unfortunately the effect of this change can not be stated, as the curtain was not submerged until the following spring, and soon afterwards that part of the dike was carried away by flood. Dike XXXIV.-The construction of this dike, like the one next above, was commenced on March 23, 1896, and twice suspended, the last time on May 12, 1896, on account of high water. It was designed as a 3-row dike, 720 feet long, with a 100-foot head. At the time work was resumed, October 5, there was 470 feet of completed dike from the shore out, and 141 piles driven in bents of 3 each from there out. The dike was completed to the project line October 31. The new work involved driving of 8 piles in bents of 2 each, the bracing of 51 bents, the making and ballasting of 580 linear feet or 27,050 square feet of foot mattress, and the curtaining of 44 bents. The systems of bracing and curtaining this dike were the same as those on Dike XXXII. Dike XXXIII.-The extension of this dike to the project line was commenced October 5 and completed on the last day of that month. Originally the structure was designed as a 4-row high dike, and 1,300 feet of it, from the shore out, had been so built up to the time when work was suspended, May 18, 1896. By your direction the extension, 700 linear feet, was made of 2-row low work. The top of the new work was at an elevation 2 feet above standard low water at the outer end and ENG 97-246 |
