tenance, to a depth of 30 feet, of the basin as thus enlarged to within 75 feet of the pierhead line; for the maintenance to a depth of 30 feet in the Santa Fe Channel to within 50 feet of the established harbor lines; for approach areas 32 feet deep to within 75 feet of the pierhead line in the outer harbor at Point San Pablo, Point Orient, and Richmond Long Wharf; for a channel 20 feet deep, 150 feet wide and about 2,000 feet long from deep water in San Pablo Bay easterly along the north side of Point San Pablo; and for a training wall 10,000 feet long extending in a general westerly direction from Brooks Island. All depths refer to mean lower low water. The tidal range between mean lower low water and mean higher high water is 5.8 feet, with an extreme range of - about 11 feet. The estimate of cost of new work, revised in 1945, is $877,300. The latest (1940) approved estimate for annual cost of maintenance is $47,500.

Contain latest published maps. Local cooperation.-The act of June 20, 1938, requires that local interests furnish necessary rights-of-way and spoil-disposal areas for initial work and subsequent maintenance and that no portion of the channel widening north of Point Potrero authorized by that act be undertaken until assurances are received that industries will avail themselves of the improved navigation facilities. The act of March 2, 1945 requires local interests to furnish necessary rights of way and spoil disposal areas. These requirements have not been complied with. All prior requirements have been fully complied with. Terminal facilities.-In the inner harbor there are two modern deep-water terminals, one oil wharf, one private general cargo wharf, two ferry terminals, three outfitting wharves, and five small wharves used for miscellaneous purposes. In the outer harbor there are three oil wharves, one deep-water general cargo wharf, one car ferry terminal, one auto ferry terminal, and one barge wharf. The facilities are considered adequate. (See Port Series No. 12, Corps of Engineers.) Operations and results during fiscal year.-The inner and outer harbors were kept free from floating debris. The normal cond tion surveys were made. The cost was $5,764.04 for maintenance The expenditures were $5,852.28. Condition at end of fiscal year. The existing project is about 92 percent complete. The work remaining to be done is the widering of the channel north of Point Potrero and the dredging of the channel in San Pablo Bay adjacent to the north side of Point Sa Pablo. In May 1945, the controlling depth in the inner harbor was as follows: Channel from San Francisco Bay to the basin at Terminal No. 1 and thence to Point Potrero, 28 feet; thence to the head of the project, 27 feet; in turning basin at Terminal No. 1 26 feet. At the end of the year the controlling depth was 30 fee: in each of the approach areas in the outer harbor except at the northeast extremity of the area at Richmond Long Wharf, where it was 28 feet, and in the southeast extremity of the area at Terminal No. 4 at Point San Pablo, where it was 29 feet. The cost of the existing project to the end of the fiscal year was $788,233.24 for new work ($683,233.24 from regular funds and $105,000 from Public Works funds) and $441,536.79 for maintenance, a total of $1,229,770.03. The total expenditures were $1,229,907.48. In addition, the costs and expenditures from cortributed funds were $524,777.66 for new work and $34,800.20 for maintenance, a total of $559,577.86. Proposed operations. The balance available, together with accounts receivable, June 30, 1945, and an allotment of $25,000 made in July, amounting in all to $59,842.59 will be applied as follows: New work: Dredging the project channel in San Pablo Bay along the north side of Point San Pablo, by contract, August 1945 Maintenance: $25,000.)

SAN PABLO BAY AND MARE ISLAND STRAIT, CALIF. Location. The channel extends from a point in the lower end of San Pablo Bay west of Pinole Point in a general northeasterly direction across Pinole Shoal in San Pablo Bay to the junction of Carquinez Strait and Mare Island Strait, thence northwesterly in Mare Island Strait along the frontage of the Mare Island Navy Yard. (See U. S. Coast and Geodetic Survey Chart No. 5533.) Previous projects.-Adopted by the River and Harbor Acts of June 13, 1902, February 27, 1911, and August 8, 1917. For further details see p. 1680, Annual Report for 1938. 672607-46-pt. 1, vol. 2-53 Existing project. This provides for dredging a channel across Pinole Shoal in San Pablo Bay 600 feet wide and 35 feet deep. thence through Mare Island Strait a channel 700 feet wide and 3 feet deep flaring to a turning basin generally 1,000 feet wide from existing dike 6, Mare Island, to a line 75 feet southerly from the causeway between Vallejo and Mare Island, 30 feet deep, except at the northerly end where the project depth is 26 feet. The proj ect provides also for two approach areas 20 feet deep to withi 50 feet of the pierhead line adjacent to the improved waterfront at Vallejo and South Vallejo and for maintenance of the two ap proach areas to the navy yard piers at the southern end of Mare Island. All depths refer to mean lower low water. The tidal range between mean lower low water and mean higher high water is 5.8 feet at the lower end of San Pablo Bay, and 6.0 feet opposite the Mare Island Navy Yard, with an extreme range of about 10 feet. The estimate of cost for new work, revised in 1941, is $290,300 exclusive of amounts expended on previcus projects. The latest (1941) approved estimate for annual cost of maintenace is $197,500. The existing project was authorized by the following river and harbor acts: Terminal facilities.—There are 3 wharves along the southern shore of San Pablo Bay, 11 wharves and 1 ferry slip along the southern shore of Carquinez Strait, and 5 wharves on the northern shore of this strait; in Mare Island Strait there are 6 commercial wharves and 3 ferry slips, in addition to the navy-yard facilities. The facilities are adequate. (See Port Series No. 12, Corps of Engineers.) Operations and results during fiscal year. The U. S. hopper dredges Kingman, Michie, and Davison worked in various periods in Mare Island Strait removing a total of 899,312 cubic yards therefrom. The project was patrolled for the removal of floating debris. The cost was $65,477.51 for maintenance. The expenditures were $64,385.55. Condition at end of fiscal year. The project is about 97 percent complete. The work remaining to be done is the dredging of the two approach areas adjacent to Vallejo and South Vallejo. At the end of the year the controlling depth throughout the Pinole Shoal channel was 35 feet. In Mare Island Strait it was as follows: 28 feet to pier No. 3, Mare Island, thence 26 feet to the turning basin, thence 25 feet in the turning basin except near the upstream end thereof where it was 23 feet. The cost of the existing project to the end of the fiscal year was $282,669.05 for new work and $1,807,518.78 for maintenance, a total of $2,090,187.83. The expenditures were $2,088,235.58. Proposed operations.-The balance unexpended June 30, 1945, together with an allotment of $7,600 made in July and an additional allotment anticipated later in the year, will be applied as follows: Accounts payable June 30, 1945 New work: Dredging the approach areas adjacent to the improved waterfront at Vallejo and South Vallejo, with Government hopper dredge, December 1945 Maintenance: Redredging the channel and turning basin in Removal of floating debris from San Pablo Bay Total maintenance Grand total $193, 504. 30 $1,952. 25 7,600.00 4,800.00 198, 304. 30 207,856. 55 The additional sum of $215,000 can be profitably expended during the fiscal year 1947 for maintenance, redredging the channel and turning basin in Mare Island Strait and the channel across Pinole Shoal in San Pablo Bay by Government hopper dredge intermittently 'hroughout the year, and in the removal of floating debris with leased plant and hired labor throughout the year.
