SAGINAW RIVER, MICH. $500 104, 000 Location. This river is formed by the union of the Tittabawassee and Shiawassee Rivers, is about 22 miles long, and flows in a northerly direction and into the south end of Saginaw Bay, Lake Huron. (See U. S. Lake Survey Chart No. 5.) Previous projects.-Authorized by River and Harbor Acts of June 23, 1866, June 23, 1874, June 18, 1878, March 3, 1879, August 2, 1882, and August 5, 1886. For further details see page 1957 of Annual Report for 1915, and page 1550 of Annual Report for 1938. Existing project. This provides for a channel 21 feet deep and 200 feet wide from deep water in Saginaw Bay to the Detroit & Mackinac Railway bridge in Bay City, thence 20 feet deep to the Sixth Street Bridge in Saginaw, Mich., thence 161/2 feet deep to the junction with the Tittabawassee River, a distance of about 291/2 miles; and for a turning basin 15 feet deep by 360 feet wide, varying from 690 feet to 420 feet in length, adjacent to the east side of the existing channel between Court and Bristol Street Bridges. The project depth is referred to low-water datum for Lake Huron, which is taken at 578.5 feet above mean tide level at New York. Due to storms the level of the river at its mouth rises and falls about 3 feet. Spring freshets and excessive rains have caused an abnormal rise of as much as 14 feet at Saginaw. Occasionally a considerable change take place within a few hours, resulting from the raising or lowering of Saginaw Bay by violent winds. The estimate of cost for new work, revised in 1938, was $2,657,500, exclusive of amounts expended on previous projects. The latest (1937) approved estimate for annual cost of maintenance is $81,000. The existing project was adopted by the following river and harbor acts: Local cooperation.-Fully complied with. Terminal facilities.-General utility docks, and seven docks handling petroleum products, all privately owned, are located at Essexville and Bay City. The aggregate length of these docks is about 3,000 feet. Similar docks with a total length of about 1,500 feet 672607-46-pt. 1, vol. 2-42 are located in the upper river at Saginaw. In addition, the Chevrolet Motor Co. operates an industrial dock about 600 feet long and the Saginaw Dock & Terminal Co. operates a private dock about 900 feet long at Saginaw, and the Consumers Power Co. owns and operates a dock about 1,100 feet long at Zilwaukee. Turning basins have been constructed by the owners opposite the latter two docks. These terminal facilities are adequate for the existing commerce. Operations and results during fiscal year.-Contract dredging for the removal of shoal material above the 16.5-foot grade in the channel between the Sixth Street and Pere Marquette Railroad Co. Bridges and between Court and Bristol Street Bridges, including dredging to 15 feet in the turning basin was commenced September 23, 1944, and completed June 29, 1945, material in the amount of 154,486 cubic yards, field measure, being removed. The U. S. hopper dredge Meade operated over the lake section during the period August 8-September 13, 1944, removing material in the amount of 53,332 cubic yards, bin measure, at a cost of $30,057.76. The costs were $81,448.47 for maintenance, and the total expenditures were $77,269.99. Condition at end of fiscal year.-The existing project was completed in April 1942. Maintenance dredging by contract has restored project depths of 16.5 feet and 15 feet in the upper river and turning basin, respectively. Shoaling has reduced the depth in the 21-foot channel in the bay section to 19.5 feet over a width of about 100 feet. The costs have been as follows: Regular funds: New work Maintenance Total Total expenditures were $2,913,691.90. $2,081, 579. 59 836, 290.79 2, 917, 870. 38 Proposed operations.-The balance unexpended at the end of the fiscal year ($22,730.01) will be expended as follows: Accounts payable June 30, 1945___ Maintenance: Final payments on contract for maintenance dredging in the Total $4, 178. 48 11,500.00 7, 051.53 22, 730. 01 The lake section of the channel is subject to shoaling and requires periodic dredging.

This harbor is located on the west shore of Lake Huron at the extreme eastern limit of Saginaw Bay, about 29 miles across the bay from the mouth of the Au Sable River (Oscoda). (See U. S. Lake Survey Chart No. 5.) Existing project. This provides for a harbor of refuge at the mouth of Bird Creek, consisting of a harbor basin dredged to a depth of 10 feet protected by breakwater structures and for dredging an entrance channel to the harbor basin to a depth of 12 feet. The project depths are referred to low water datum for Lake Huron, which is 578.5 feet above mean tide at New York. The estimated cost for new work made in 1945, is $172,100, excluding $172,100 to be contributed by local interests. The latest (1945) approved estimate of annual cost of maintenance is $750. The existing project was authorized by the River and Harbor Act approved March 2, 1945. For latest published map see House Document No. 446, Seventy-eighth Congress, second session. Local cooperation. The improvement authorized by the act of March 2, 1945, is subject to the condition that responsible local agencies give assurances satisfactory to the Secretary of War that they will (1) Contribute $172,100 in cash toward the first cost of protective structures and dredging. (2) Provide and maintain, without cost to the United States, and in accordance with plans approved by the Chief of Engineers, a suitable and adequate public wharf for the accommodation of transient vessels. (3) Establish a competent and properly constituted public body empowered to regulate the use, growth, and free development of harbor facilities (exclusive of Federal property), with the understanding that harbor facilities shall be open to all on equal and reasonable terms. (4) Hold and save the United States free from damages due to construction and maintenance of the works. (5) Provide, without cost to the United States all lands, easements, and rights-of-way necessary for the construction of the project, including suitable spoil disposal areas when and as required.

HARBOR OF REFUGE AT HARBOR BEACH, LAKE HURON, MICH. Location. This harbor is located on the west shore of Lake Huron about 60 miles north of Port Huron, Mich, (See U. S. Lake Survey Chart No. 5.) Existing project. This provides for the formation of a harbor of refuge protected by stone-filled timber-crib breakwaters-the main breakwater being 4,716 feet long, the north one 1,204 feet long, the original north entrance, 304 feet wide, being reopened to a depth of 10 feet, and the south breakwater 1,956 feet long; for dredging the main entrance, 600 feet wide, to a depth of 23 feet; and for dredging an anchorage area approximately 3,000 feet long by 1,200 feet wide to a depth of 21 feet. The project depths are referred to a stage 578.5 feet above mean tide at New York. The normal elevation of the water surface in Lake Huron varies from year to year. During each year the level is subject to a seasonal rise and fall, the lowest stages prevailing during winter and the highest during summer months. Such yearly changes, measured by monthly mean levels, may be as much as 1.8 feet. During the past 33 navigation seasons the difference between the highest and lowest monthly mean levels during the navigation season has been about 4.9 feet. Occasional fluctuations, due to winds of high velocity, may be as much as 2 feet in 8 hours. The estimate of cost for new work, revised in 1917, was $1,658,550. The latest (1917) approved estimate for annual cost of maintenance is $10,000. The existing project was adopted by the following river and harbor acts: Terminal facilities.-There is but one dock about 500 feet long. This dock, privately owned, is open to all vessels upon equal terms and is considered adequate for existing commerce. Operations and results during fiscal year.—None. Condition at end of fiscal year.-The existing project was completed in 1928. The work consisted in the construction of three breakwaters, the dredging of an entrance channel. and the dredging of an anchorage area about 72 acres in extent under the protection of the breakwaters. The breakwaters were originally built in 1885, and since that time it has been necessary to top them with concrete and to protect about 6,170 feet of the outer face with heavy riprap. The north entrance was closed by rubble mound in 1920 and reopened to about 10 feet depth in 1928. Dredging was completed in 1922. The harbor has controlling depths of 20.5 feet at its entrance and about 18 feet within the anchorage area, as shown by survey of 1939. The breakwaters are in fair condition, except that riprap along lake face of main breakwater needs repair and some fenders on harbor face of main breakwater need replacing. The costs and expenditures have been $1,200,598.17 for new work and $1,469,741.74 for maintenance, a total of $2,670.339.91. Proposed operations.-The unexpended balance of $1,000 will be expended for a sounding survey over the entire project scheduled for October 1945. No work is proposed during the fiscal year ending June 30, 1947. |
