Contract dated November 9, 1910, for dredging about 65,307 cubic yards of material from Petaluma Creek, Cal. The only work done on this locality during the year was the removal of nine trees from a portion of the bank that was sliding into the river, taking the trees with it. This work was done by hired labor at a total cost of $45. There is need of making two cut-offs in this river at Car Bend and at Jack's Bend. It will be necessary to modify the existing project for this locality in order to provide for these cut-offs. The present project was based on a preliminary examination and survey made in compliance with the river and harbor act of July 5, 1884, and the report thereon is printed in Report of the Chief of Engineers for 1885, page 2343. The bends mentioned are pronounced; they make navigation difficult even with a good depth of channel, and the tendency to shoal is much greater at these bends than elsewhere along the river. If cut-offs were made here, the cost would not be great, and the current being given a direct course should keep the channel open. The use of the whole river would be greatly facilitated and redredging should be much less frequent. The local authorities are willing to furnish the necessary land free of cost for the right of way for each cut-off. It is recommended that the present project for this locality be modified so as to provide for making these two cut-offs. The amount of deterioration in the channel of this river since the last dredging in May, 1910, is estimated at about 24,000 cubic yards. To remove this material will cost about 12 cents per cubic yard. Estimate of additional funds required.

The project for rebuilding the jetties at this locality having been adopted by the river and harbor act of June 25, 1910, early in the fiscal year an assistant engineer was employed and sent to Eureka with instructions to study the situation and formulate a satisfactory and economical plan for obtaining stone and placing it in the jetties. Several weeks were spent on this investigation and it was decided to obtain stone by contract and place it in the jetties by hired labor. Specifications were prepared for furnishing several items of the pro posed stone receiving and handling plant and some bids were called for, but owing to the fact that the funds available were insufficient for any practical plan of work, operations were suspended pending further appropriations. The act of February 27, 1911, appropriated $170,000 for this work and placed it on the continuing-contract basis. The work was immediately taken up again and a suboffice was established at Eureka. Proposals were obtained for furnishing 500,000 tons of large stone and 44,000 tons of crushed rock, but at the end of the year contract had not been entered into. The construction of a stonereceiving and handling plant was in progress at the end of the year. This consists of a landing wharf, car ferry slip, railroad with locomotive and cars, a traveling crane and accessories. The total amount spent on this work during the year was $10,870.43. In the meantime a survey of the jetty channel was made to determine its present condition and for use as a basis to ascertain definitely the progressive effect thereon of the rebuilt jetties. This survey was completed in April, 1911, at a total cost of $2,247.36. During the latter part of the year a survey was made of channel in front of Eureka at a cost of $936.03. Owing to the limited funds available and the high cost of bringing a dredge to this locality it will not be practicable to do any work on this channel until further funds are provided. At the end of the year a survey was in progress to determine the tidal volume of Humboldt Bay and also to establish data whereby any decrease therein may be detected at any future time. A total of $720.74 had been spent on this survey. The deterioration of the works at this locality consists of the damage by storms to the outer ends of both jetties and shoaling of the channel in front of Eureka. The cost of repairs to the jetties is estimated at $1,037,400, the basis of the present approved project for rebuilding them. The shoaling of the channel in front of Eureka amounts to about 100,000 cubic yards and the cost of removal is estimated at 30 cents per cubic yard. Estimate of additional funds required. Amount that can be profitably expended in fiscal year ending June 30, 1913, for works of improvement and for maintenance. 1 $515, 000 APPROPRIATIONS. Total of appropriations to Dec. 31, 1902 (see H.
