IMPROVEMENT OF CLATSKANIE RIVER, OREG.

For history of this work, projects, and results accomplished, see current summary of this report.

OPERATIONS DURING THE FISCAL YEAR 1911.

The U. S. dredge Cowlitz commenced work on the Clatskanie River November 4, 1910, and dredged the channel to the project depth of 6 feet at low water, from the town of Clatskanie to the railroad bridge, a distance of about 1 mile.

The work was completed December 29, 1910, when the dredge and plant was towed to the Government moorings, Portland, Oreg., and laid up, December 31, for the winter.

At Chinaman Bend on each side of the river a bulkhead was constructed, consisting of a single row of piling, driven 3 feet between centers, with 3-inch by 12-inch planks spiked to inside face of piles to prevent the dredged material from returning to the channel.

In connection with the reclamation of the low, marshy lands adjacent to the river, the Columbia Agricultural Co. have during the year dredged the channel from the mouth to below the railroad bridge, using the dredged material on the levees.

The new channel previously completed by the above-mentioned company across a bend near the mouth of the river was deeded to the United States August 19, 1910, in accordance with the provisions of permit dated January 5, 1909.

IMPROVEMENTS OF COWLITZ AND LEWIS RIVERS, WASH.

For history of these works, projects, and results accomplished, see current summary of this report.

(A) OPERATIONS DURING THE FISCAL YEAR 1911 FOR COWLITZ RIVER, WASH.

No work was done on the Cowlitz River during the fiscal year except blasting 24 snags from the channel between Toledo and Olequa and clearing the overhanging brush from the river in the vicinity of Keegan Bar.

The season for active operations was too far advanced before the necessary repairs to the dredging plant were completed, and as the period for dredging operations is somewhat limited, it was deemed more economical and advantageous to commence the work after the summer freshet in the Columbia River begins to recede.

Under permits to dredge for sand and gravel for commercial purposes, the Cowlitz Bridge Co. and the Hurley, Mason Co. removed 2,386 and 2,616 cubic yards, respectively, of material from the channel of the river during the fiscal year.

During the early part of the year the dipper dredge No. 1, subsequently named Cowlitz, was overhauled, new spuds and boom installed, boiler, engines, and machinery placed in good condition, and a 14-cubic yard clam-shell bucket purchased. During the winter months the house of the dredge was remodeled and living quarters for the crew built, and in addition to the bucket rigging a supplemental 8-inch centrifugal sand-dredging plant was installed for the purpose of pumping sand in the tidal portions of the stream, where this method of dredging is applicable.

Estimate of additional funds required.

Amount that can be profitably expended in fiscal year ending June 30, 1913, for maintenance of improvement..
