11. CROOKED CREEK RESERVOIR, PA. Location. The dam site is located on Crooked Creek, 6.7 miles above the junction of the creek with the Allegheny River near Ford City, Pa., and about 32 miles northeast of Pittsburgh, Pa. The reservoir is located entirely in Armstrong County, Pa. (See U. S. Geological Survey charts for Freeport and Elders Ridge, Pa.)
Existing project. This provides for the construction of a flood control reservoir dam of the earth-fill type with separate untontrolled saddle spillway and tunnel outlet works. The dam is 1,480 feet long at the top, rises 143 feet above the stream bed, and provides for the gross storage of 93,900 acre-feet of water from a tributary drainage area of 278 square miles. Of this storage 89,400 acre-feet are available for food prevention at Pittsburgh and in the upper Ohio Valley, generally. The remaining 4,500 acre-feet are in permanent storage. The reservoir is operated as a unit of a coordinated reservoir system for the protection of Pittsburgh and the upper Ohio Valley generally. The existing project was authorized by the Flood Control Act approved June 22, 1936. The estimated cost of new work, revised in 1943, is $4,300,000.
Local cooperation. Section 2 of the Flood Control Act approved June 28, 1938, applies.
Operations and results during fiscal year—New work.—Some preliminary work was performed consisting of miscellaneous engineering work. In connection with the acquisition of land in the reservoir area, a total of 536.55 acres in fee simple and flowage easements over 0.98 acre was acquired this fiscal year.
Maintenance (operating and care).—The reservoir was operated for benefit of food control, as required, and necessary repairs were made to the dam and to operators' quarters and grounds throughout the fiscal year. In addition to ordinary maintenance and repairs to structures and plant, repairs to the service gates were under way. The Ohio River at Pittsburgh was above flood stage three times during the year, and on four other occasions, rises occurred which crested between 20 and 25 feet. The three largest floods on February 28, March 4 and March 7, 1945, crested at 27.7, 26.9 and 33.4 feet, respectively. Storage was made during each of these floods, but as the intervals between floods were short, total release of the impounded water could not be effected until after the last flood. The reservoir water surface reached levels of 36.7, 39.0 and 57.7 feet above the minimum pool on March 1, March 5, and March 9, 1945, respectively. The highest level reached during the year, on March 9, represents an impoundment of 51,500 acre-feet, or about 60 percent of the capacity available for flood control purposes. Results of reservoir operations in the reduction of flood stages at Pittsburgh, Pa. and Wheeling, W. Va., in combination with other units in the reservoir system are shown in the corresponding paragraph for Tygart River Reservoir. During the remainder of the year operations were routine except on the occasion of several minor rises, when some water was stored and released as river conditions permitted.
The total costs were $16,238.17, of which $1,030.20 was for new work and $15,207.97 for maintenance. The total expenditures were $17,227.74.
Condition at end of fiscal year.—The dam is complete and the reservoir is in operation as a unit in the reservoir system designed for the protection of Pittsburgh and the reduction of flood heights in the upper Ohio Valley, generally. Work remaining to be done consists of preliminary work; certain miscellaneous appurtenances to the dam; construction of a storage building; and making settlement with the Commonwealth of Pennsylvania for reimbursement for certain utility relocations performed by the Commonwealth under the requirements of the 1936 Flood Control Act. All work necessary to the acquisition of land in the reservoir is approximately 98 percent complete. The total acreage involved has been acquired, and consists of 2,563.55 acres in fee simple and flowage easements over 99.98 acres. Under the 1936 Flood Control Act, the Commonwealth of Pennsylvania acquired the dam site for this project, the transfer of which title has not as yet been consummated.

12. JOHNSTOWN, PA., CHANNEL Location. The city of Johnstown is located in southwestern Cambria County, Pa., approximately 58 miles east of Pittsburgh, Pa. It is situated in a deep and comparatively narrow valley at the junction of Stony Creek and Little Conemaugh River, which unite to form the Conemaugh River. (See U. S. Geological Survey chart for Johnstown, Pa.)
Existing project.—The plan of improvement provides for increasing the channel capacity by enlarging and realining the existing channels and protecting the banks with concrete pavement. Miscellaneous features of work include relocation of railroad track, highway and utilities, and alterations to sewers, drains, bridge piers, and other structures. The improvement involves about 47,300 feet of channel as follows: The Conemaugh River for a distance of 19,100 feet extending from the "Point" downstream to about 2,650 feet below the Pennsylvania Railroad bridge at Dornick Point: the Little Conemaugh River for a distance of 7,500 feet from the “Point” upstream to about 150 feet below the Pennsylvania Railroad bridge in the vicinity of Fifth Street; and Stony Creek for a distance of 20,700 feet from the “Point” upstream to about 500 feet above the Ferndale Bridge in the vicinity of the borough of Ferndale. The project is designed to accommodate discharges equivalent to those of the March 1936 flood, the maximum natural flow of record, with a minimum of overbank flow and to practically eliminate damages therefrom. The existing project was authorized by the Flood Control Acts, approved June 22, 1936, and August 28, 1937.
The estimated cost of new work, revised in 1942, is $8,670,000, of which $7,793,000 is for construction and $877,000 for rights-ofway and damages.
Local cooperation.—Section 2 of the Flood Control Act approved June 28, 1938, applies.
Operations and results during fiscal year.–New work.—Some preliminary work was performed consisting of miscellaneous engineering work. In connection with the acquisition of land, flowage easements over 216.38 acres were acquired during the year.
Maintenance.Bids were received for the removal of a bar formed at the junction of Little Conemaugh River and Stony Creek and were rejected due to unsatisfactory bids. This bar was resurveyed and the information obtained will be used in soliciting new bids for the removal of the bar under contract. In addition, repairs to a portion of footers of the slope paving below the Walnut Street bridge were partially completed,
The total costs were $140,462, of which $130,389.67 was for new work and $10,072.33 for maintenance. The total expenditures were $158,290.98.
Condition at end of fiscal year.—The improved channels are fully complete. Construction was accomplished by units, consisting of units Nos. 1, 2, 3, and supplementary unit No. 2A, all in the Conemaugh River section, unit No. 4 comprising the Little Conemaugh River section, and units Nos. 5 and 6 comprising the Stony Creek section. All work necessary to the acquisition of land is approximately 96.5 percent complete. To date, about 96.3 percent of the total acreage involved has been acquired and consists of 0.60 acre in fee simple and flowage easements over 382.78 acres, the former being fully complete. Remaining work consists of miscellaneous engineering work and concluding the acquisition of land.
