the cut was completed there to partial width June 3, 1911, 45,546 cubic yards of sand having been removed from the shoal at this time and a small portion pumped behind a bulkhead on the west shore, and the balance on the east shore. During the year 25 new pontons were built at Coos Bay, by hired labor, to give a longer pipe line, and the dredge was maintained in good repair. In all, 418,150 cubic yards of material were excavated on the project at Coos Bay during the fiscal year, and this work, together with that of former years, has resulted in a channel up the bay to the C. A. Smith mill above Marshfield at least 160 feet wide, with a controlling depth of 17 feet at mean lower low water. On June 3, 1911, the dredging work at Coos Bay was suspended, as the Oregon was needed at the Coquille to complete the dredging project there, while the conditions permitted of her being towed to and from that place. The dredge, together with the pontons and pipe line, was towed to the Coquille on June 8, 1911. It is thought that the dredging on the Coquille will be completed and the Oregon taken back to Coos Bay by September or October, 1911, and the work of completing the projected bay channel in Coos Bay will be completed during the next fiscal year. As the present dredged cut at Coos Bay is in an unfinished condition and several changes have taken place in the channels of the bay since the last survey, a new survey of the hydrography of the upper part of the bay from the C. A. Šmith mill to a point below Pony Slough, as a guide to future work, is being made and will be finished at an early date. Progress has been made on the preparation of plans in Washington, D. C., for a seagoing hydraulic dredge for service on the bar, at a cost of $350,000, as provided for in the approved project. It will probably be more than a year before this seagoing dredge is ready for service. In compliance with the requirements of the river and harbor act of June 25, 1910, an examination was made of Coos Bay with a view to the removal of Guano Rock. Report thereon was submitted by the district officer December 5, 1910, in which it was found that the proposed improvement was not worthy of being undertaken by the General Government.

Information concerning the project for this improvement will be found in the summary of this report. OPERATIONS DURING THE FISCAL YEAR 1911. The act of June 25, 1910, appropriated $3,000 for maintenance. The Government snag scow and dredge were put in order in August, 1910, and operated on Coos River by hired labor until November 21, 1910, removing all troublesome snags from the head of navigation on both forks to the mouth. During the season 228 large and 330 small snags were removed and placed on the banks. In addition to the snagging the dredge bucket was rigged and 2,200 cubic yards removed from Island Shoal on the South Fork, and the channel of the North Fork was dredged below Allegany for about 600 feet downstream. Active operations ceased on November 21, leaving the river in excellent condition. The total cost of this work was $3,217.75. It is estimated that an appropriation of $3,000 will be necessary for maintenance during the fiscal year 1913. Estimate of additional funds required. Amount that can be profitably expended in fiscal year ending June 30, 1913, for maintenance of improvement...... 1 $3,000 APPROPRIATIONS. Total appropriated to Dec. 31, 1902 (see H. Doc.
