IMPROVEMENT OF KENTUCKY AND TRADEWATER RIVERS, KENTUCKY; BIG SANDY RIVER, KENTUCKY AND WEST VIRGINIA; AND OF GUYANDOTTE AND LITTLE KANAWHA RIVERS, WEST VIRGINIA. REPORT OF CAPTAIN JAMES C.

UNITED STATES ENGINEER OFFICE, GENERAL: I transmit herewith the annual reports for the fiscal year ending June 30, 1884, for the several works of improvement under my IMPROVEMENT OF KENTUCKY RIVER, KENTUCKY. During the past fiscal year navigation upon the portion of this river improved by repairing the locks and dams, which extends a distance of 82 miles from its mouth, has been continuous, except during the months of August and September, when the water in the Ohio River became so low that it was extremely difficult, and part of the time impossible for steamers to approach Lock No. 1, and also a portion of January and February, when the extreme high water and ice made it exceedingly dangerous to attempt navigation. Advantage was taken of last season's low water to draw down the pools and make a careful examination of each of the dams to ascertain what repairs were needed to render them safe. The following are the results of this examination: Dam No. 1 was ascertained to be leaking badly, part of the water escaping under and through the work closing the breach. This dam was also found to be too low to maintain the proper depth of water at No. 2 during low water. Dam No. 2 leaked badly at several points. Dam No. 3 was in excellent order, needing only trifling repairs. Dam No. 4, which had lost its entire apron several years ago, was in a dangerous condition, leaked badly, and needed extensive repairs. The balance of the appropriation remaining on hand being small, only such work was done as was found to be absolutely necessary for the continuance of navigation. This consisted of resheeting Dam No.1 its entire length, placing sheet piling in rear of it to the depth per mitted by the stone ballast that had fallen out of the cribs, and filling in behind the sheet piling and breach-closing work with backing. The leaks in Dam No. 2 were stopped, principally by additional backing, and an entire new apron, 528 feet long and 26 feet high, was constructed at Dam No. 4, which added to its base a width of 34 feet. Additional details of the work done are given in the report of D. L. Sublett, assistant engineer, forwarded herewith. In the latter part of April, the water in the river having fallen sufficiently, a party was sent into the field under the charge of R. S. Burnett, assistant engineer, to make a survey for the location of Locks and Dams Nos. 7 and 8. This survey was extended over a distance of 444 miles, commencing at Oregon, near where it is proposed to locate lock and Dam No. 6. Much of the information obtained was required before the site of No. 6 could be definitely determined. This survey also developed the existence of numerous snags and overhanging trees, and a mass of rocks about a mile from the Brooklyn Bridge, or 171⁄2 miles above Oregon, which it will be necessary to remove. The removal of these Mr. Burnett estimates at $15,500. No provision having been made by Congress for the purchase of the land necessary for the construction of the lock and dam at Beattyville, Three Forks, provided for in the act of August 2, 1882, this work was not commenced. In order to obtain a full discussion of the meaning and intention of the law, as well as the needs of commerce of this locality, a request was made to the Chief of Engineers to submit this subject to a Board of Engineers for consideration; and a Board was accordingly appointed. The preliminary report of the Board was printed as House Ex. Doc. No. 36, Forty-eighth Congress, first session. The country adjoining the Three Forks abounds in coal and iron of excellent quality, which cannot now reach a market without great diffi culty. The principal object of the proposed dam is to create a pool extending well into these streams to enable boats to load with coal at the mines, and remain afloat until such a time as the water is sufficiently high for them to proceed down the river. This pool will also form a secure ice-harbor, where boats that are loaded can remain in safety while waiting for the river to rise. At present the boats are constrcted on dry sand or gravel bars, where they are loaded, and remain until a rise carries them down the river. This precarious system of navigation often causes great loss, and the coal and iron interests of this locality have not been able to develop, nor can they, so long as they must rely upon this uncertain means of transportation. The extension of the slackwater system upon the Kentucky River to this point, whereby a safe and easy means of communication will be made between this exceed. |
