Information relating to location of Locks and Dams Nos. 1 to 8 may be found in the Annual Report of the Chief of Engineers for 1899, page 2523. Reference is also made to page 2012 et seq. of Annual Report of the Chief of Engineers for 1898, in which the condition of Kentucky River is described in 1879 when ceded to the United States by the Commonwealth of Kentucky. There are nine locks and dams open to navigation on the Kentucky River. The first lockage through Lock No. 9 was made December 3, 1903. This lock is 17.4 miles above Lock No. 8, and 157.2 miles from the Ohio River. These locks have been in operation during the fiscal year, except as noted below: Lock No. 1: 26 days by ice, 30 days submerged by freshet in Ohio River. Total number of days, 56. Lock No. 2: 26 days by ice, 4 days submerged by freshet in Ohio River. Total number of days, 30. Lock No. 3: 26 days by ice, 4 days repairs to lock gates. Total number of days, 30. A depth of 6 feet at pool stage exists at close of year throughout the improved portion of the river except in lower entrance at Lock No. 2, where there is 5.85 feet, and on the upper miter sill at Lock No. 4, where there is scant 5.6 feet. The highest stage of the river was 14.4 feet, being the upper gauge reading at Lock No. 4 on March 27, 1904, or 8.8 feet above pool level. The Kentucky River is now navigable to Lock No. 10, near Ford, Ky., 176 miles from the Ohio River. A statement of the work accomplished during the last fiscal year is as follows: Lock No. 1.-A concrete saddle was constructed to raise the crest of dam 1 foot for a distance of 50 feet from the river wall of the lock; 34 cubic yards of concrete were laid; 80 cubic yards of concrete were placed in repairs to lower slope of dam; 725 cubic yards of derrick stone were placed at toe of dam and of abutment, to counteract the effect of scour; 310 cubic yards of riprap were placed to protect bank at abutment. Owing to repairs made elsewhere on the river, this work was started late in the season and was not completed; repairs were also made to coping of lock walls and to grounds and houses. Lock No. 2.-Two hundred and ninety linear feet of down-river slope and apron of this dam were reconstructed of concrete, completing the work undertaken in 1903 and not then finished; 1,698 cubic yards of concrete were used to complete these repairs; 141 linear feet of upper land-approach wall extending immediately above lock wall was renewed with concrete, 358 cubic yards placed. Mr. John Short completed the lower approach walls under an openmarket agreement. These are constructed with concrete. Lock No. 3.-The lower land-approach wall was reconstructed by Mr. John Short, under an open-market agreement. This was constructed with concrete. Lock No. 4.-The lower land-approach wall, rotted by age, has been removed and work of constructing isolated concrete piers with grillage is now in progress. Minor repairs to houses and grounds have been made. Machinery and appliances pertaining to operating and care, Kentucky River, have been kept in serviceable condition and various incidental repairs have been made here by the regular force to water crafts and lock grounds. Lock No. 6.-Minor repairs have been made to screens of filling culverts. Lock No. 8.-Repairs to timber-crib dam have been completed; 846 cubic yards of derrick stone placed in lower step and at toe of dam; 510 cubic yards concrete placed in lower step. United States dredges. Both dredges have been actively engaged during the working season in dredging and assisting in work of reconstruction at Locks Nos. 1 and 2. Dredge No. 1 has operated at Leestown bar, Canoe Creek shoal, Little Benson bar, in lower entrance, Lock No. 9, assisted in reconstruction of approach walls and repairs to dams at Locks Nos. 1 and 2, and placed backing to check leakage of Dam No. 2. Total number of cubic yards excavated.. Cost per cubic yard..... 37,900 $0.0971 Dredge No. 2 removed deposits from Locks Nos. 1 to 8, inclusive, assisted in repairs to Dam No. 1; placed backing to check leakage of Dams Nos. 4, 5, and 6. Total number of cubic yards excavated 28, 207 $0.1501 The expenses incurred in towing the dredges by the various towboats acting as tenders are not included in the average cost per cubic yard, nor are the wages of the crews charged while they were assisting in reconstruction work at Locks Nos. I and 2. The result of the dredging operations have been to maintain a good navigable channel through all bars and shoals in the slack-water system of the Kentucky River formerly impeding navigation, and the lock pits and approaches have been kept free from deposits at low stages of river. The U. S. towboat Genl. O. M. Poe has been employed during the working season of 1903 in towing Engineer Department water crafts and in assisting in reconstruction work; has been since May 30, 1904, undergoing extensive repairs at Cincinnati, Ohio. Summary of expenditures for operating and care of locks and dams on Kentucky River, Kentucky, for fiscal year ending June 30, 1904. expe The new concrete dam at No. 9, with 18 feet lift, had its first rience with logs during the past winter. From this we learned that the "back lash" or "reaction" is to be dealt with in such constructions. The effect seemed to be worse with the gauge at 18 feet, when logs were held sometimes as long as thirty hours, going back to the dam with a savage blow, then diving and reappearing, perhaps to circle, then to repeat the attack. The ends of such logs were so badly hammered that the owners are not likely to wish a repetition of the experience with valuable timber, but the effect on the downstream face of the dam at such levels was marked. Horizontal cuts are made, perhaps a foot deep, certainly more than 6 inches (the water is not yet low enough to allow of exact measurement), and the greater part of the middle downstream face of the dam is marred. Also there is a torn space on the lower crest for some 30 feet. It is proposed to excavate the cut holes and put in timbers, with driftbolts, to act as cushions, for the present at any rate. Perhaps a more gentle slope, as at Nos. 1 and 2, would lessen this trouble. At any rate nothing of this character is reported from either of these two dams, both recently topped with concrete.
