3. GREEN, BARREN, AND NOLIN RIVERS, AND BEAR CREEK, KY.

Location.—Green River rises in Casey County, Ky., flows in a northwesterly direction 370 miles, and empties into the Ohio River about 8 miles above Evansville, Ind.

Barren River rises in Monroe County, Ky., flows in a northwesterly direction 130 miles, and empties into Green River one-half mile above lock No. 4 and 149.5 miles above the mouth of Green River.

Bear Creek rises in Grayson County, Ky., flows in a southerly direction 40 miles, and empties into Green River 0.3 mile above new lock No. 5 and 168.4 miles above the mouth of Green River.

Nolin River rises in Larue County, Ky., flows in a southwesterly direction about 105 miles, and empties into the Green River 1.8 miles above lock No. 6 and 183.5 miles above the mouth of Green River.

Existing project.This provides for the purchase of improvements made prior to 1884 by the State of Kentucky, consisting of locks and dams Nos. 1 to 4, Green River, and No. 1, Barren River, which gave a continuous 4-foot depth for navigation from Bowling Green, on the Barren River, to the mouth of Green River; the reconstruction of lock No.2, Green River; the upstream extension of slack-water navigation on Green River to Mammoth Cave, Ky., by the construction of locks and dams Nos. 5 and 6 and by the removal of snags and slides; the construction of new locks at dam No. 1, Barren River, and at dam No. 5, Green River; the raising of the crest of dam No. 5, Green River, 2 feet, by means of a movable A-frame top; the improvement of Nolin River by the removal of obstructive bars, boulders, overhanging rocks, and snags; and the improvement of Bear Creek by removing snags and widening the bends.

The project for Green River extends from the mouth to Mammoth Cave, Ky., a distance of 197.8 miles; for Barren River from the mouth to Bowling Green, Ky., a distance of 30.1 miles; for Nolin River from the mouth to Meredith Ferry, a distance of 734 miles; and for Bear Creek, Ky., for a distance of 8 miles above its mouth. The navigable depth of the improved portions is limited to 5.5 feet by the elevations of the existing lock miter sills.

Fluctuations in stage vary considerably at the different locks. At lock No. 3, Green River, ordinary fluctuations due to high stages are from 12 to 15 feet above the pool level, and at lock No. 1, Barren River, from 7 to 10 feet above pool. The maximum stages of record are 34 feet above normal pool stage at lock No. 3, Green River, and 29 feet at lock No. 1, Barren River. These stages were obtained during the floods of 1937 and 1913, respectively.

The principal data concerning the locks and dams are shown in the following table:

At normal pool dam 48, Ohio River.

Distance from mouth of Green River is 164.5 miles. a With movable A-frame crest 3 feet high. Includes $4,033.50 for purchase of land.

Does not include $179,434.58, cost of old lock and dam No. 5. * Includes $729,269 for the new large lock completed in 1934, of which $1,800 was for purchase of land.

The estimated cost of new work in Green and Barren Rivers, revised in 1930, is $2,796,540; of new work in Nolin River, $15,000; and of new work in Bear Creek, $23,000, of which $10,000 is to be contributed by local interests; a total of $2,834,540.

The estimated cost of the maintenance of the channel in Green, Barren, and Nolin Rivers, revised in 1942, is $25,000; and in Bear Creek, made in 1927, $500 per annum. The estimate of annual cost of operation and care of the locks and dams, revised in 1942, is $65,000.

Local cooperation.—The River and Harbor Act of July 3, 1930, provides that in connection with the improvement of Bear Creek, Ky., local interests are to contribute $10,000 to the first cost of the dredging, provide necessary rights-of-way at the bends, furnish without cost to the United States satisfactory areas for the disposal of excavated material, and assume all flowage damages along Bear Creek. These conditions have not been met.

The River and Harbor Act of August 30, 1935, provides that local interests provide any land or easements required for the purpose of the improvement of Nolin River. Local interests have been unable to obtain easements required for the removal of overhanging rock ledges at Whistle Mountain.

Terminal facilities. There are six terminals on Green River, five of which are for handling petroleum products and one for unloading logs. On Barren River there are four terminals, two of which are petroleum terminals, one is for transfer of asphalt from barge to railroad and the other is the public landing at Bowling Green, Ky. The only terminal on Nolin River consists of one conveyor for loading asphalt at Kyrock, Ky. There are no terminals on Bear Creek. These facilities are considered adequate for existing commerce.

Operations and results during fiscal year.–Work during the fiscal year consisted of the operation and care of the seven locks and dams on the Green and Barren Rivers at a cost of $64,971.95, and the maintenance of the channels in the pools of the dams at a cost of $43,836.03, a total of $108,807.98. The expenditures were $109,758.85.

Condition at end of fiscal year. The canalization system on Green and Barren Rivers is in only fair condition, except Lock No. 1, Barren River and Lock and Dam No. 5, Green River, which are

in excellent condition. The controlling navigable depth in the sections covered by the existing project was 5.5 feet at the end of the fiscal year. New work remaining to be done consists of removing overhanging rock ledges at Whistle Mountain on Nolin River, provided for by the River and Harbor Act of August 30, 1935, and the improvement of Bear Creek, provided for by the River and Harbor Act of July 3, 1930. The costs to the end of the fiscal year were as follows:

The total expenditures were $3,365,648.06, including $85,000 Public Works Funds and $2,000.00 Emergency Relief funds. In addition, the sum of $3,842,667.40 was expended between 1888 and June 30, 1936, on the operating and care of the works of improvement under provisions of the permanent indefinite appropriation for such purposes.

4. ROUGH RIVER, KY. Location. This stream is one of the principal tributaries of Green River and lies wholly within the State of Kentucky. It rises in Hardin County, flows westerly 136 miles, and empties into Green River at Livermore, 71 miles from the mouth of that river. (See U. S. Geological Survey charts, Kentucky quadrangles: Central City, Hartford, Whitesville.)

Existing project.--This provides for clearing the river of obstructions and for the construction of a lock and dam to carry slack water to Hartford, Ky. The new work provided for having been completed, the project now contemplates the maintenance of the lock and dam and keeping the river channel free from the snags and other obstructions to navigation.

At the lock the ordinary fluctuations due to floods vary from 6 to 10 feet above pool level. During the flood of 1937 a stage of about 26 feet above pool stage was reached.

The location and principal dimensions, etc., of the lock are as follows:
