The available depth of water in the jettied channel is about 12 reet at low water. Effort was made during the past season to increase this depth by dredging. The material to be removed consisted mainly o.. hardpan, which proved to be very difficult to excavate. It was not found economical to attempt to remove it with a dredge alone. It will have to be first broken up with explosives. This work will be continued this season. July 1, 1891, balance unexpended.

5. Oswego Harbor, New York. The earliest project for the improvement of this harbor was adopted in 1827, and proposed to inclose an area at the mouth of the Oswego River by extending jetties from the shore into the lake, joining the outer ends by a breakwater, and leaving an opening through which to enter the harbor. This project was completed in 1869, and forms the present inner barbor.

The present project was adopted in 1870, and consists of a breakwater 5,800 feet in length, generally parallel to the old west breakwater, and 1,100 feet in advance of it. The estimated cost was $1,161,682. This estimate of course did not include its subsequent repair and maintenance. This project was afterwards modified by the proposed construction of an east breakwater 2,700 feet in length, the reduction to 350 feet of the opening between the east end of the west breakwater and the north end of the light-house pier, the construction of spurs along the face of the outer west breakwater to reduce the effect of accumulated seas, and to provide for deepening by dredging the inner harbor at the mouth of the Oswego River.

The act of Congress of August 11, 1888, provided for the removal of the outer east breakwater, of which 250 feet had been built. This has been done, and the construction of an east breakwater now forms no part of the project.

In 1890 the project was further modified by providing for the protection and permanent maintenance of an opening that had been formed by waves in a storm through the outer breakwater near the western angle; the object of this opening being to keep the water in the harbor pure by allowing a circulation through, and to provide another entrance for small vessels. The natural entrance to the mouth of the the river was shallow and difficult of access, and afforded very little shelter to vessels of any considerable size.

The object of all these improvements has been to give protection and shelter to the city docks and wharves and to the commerce of the harbor, and to make a depth suitable for the deepest draft vessels on the lake.

The total amount expended from the adoption of the project to June 30, 1892, is $1,759,842.31.

The amount expended from the adoption of the present project in 1870 is $1,286,461.44. The total expenditure has resulted in the completion of the original project of 1827, and in the construction of the outer west

breakwater; the reduction to 350 feet of the opening between the east end of this breakwater and the north end of the light-house pier, the construction and removal of about 250 feet of the east breakwater, the completion of two spur cribs, and the deepening of the river mouth to a depth of 15 feet at low water; in the securing full protection to the docks and wharves west of the river mouth, and channels of entrance 16 feet deep and 350 feet wide to the inner and outer harbors, and in securing increased depth in the inner harbor.

In addition, the various works have been cared for and maintained, and the perishable portions renewed when necessary, from the beginning of the work in 1829 to the present time.

The operations of the fiscal year have been the renewal of the superstructure on 170 feet of the outer breakwater; the removal by dredg. ing of about 17,000 cubic yards of gravel and stone from the river mouth in the inner harbor, increasing the available depth about 2 feet; the removal by dredging of 10,000 cubic yards of sand from the outer harbor along the breakwater, increasing the available depth from about 10 or 12 feet to 17 feet, and general repair work to the permanent structures as it was required.

6. Harbor at Sacketts Harbor, New York.The project for the improvement of this harbor was adopted in 1881, and proposed the deepening of the harbor by dredging over an area of about 15 acres to a depth of 12 feet at low water. The depth previously existing was less than 8 feet over a large part of this area. In 1826 and 1828 the sum of $6,000 was expended in clearing and deepening this harbor.

The total amount expended from 1826 to June 30, 1892, is $14,368.01. The amount expended from the adoption of the present project to June 30, 1892, is $8,368.01, and has resulted in the removal of 24,010 cubic yards of sand, mud, and gravel from the harbor, and in the construction of a stake and fascine dike 164 feet in length, with a mooring crib 18 feet square at its extremity to shelter the basin and exclude gravel drift from it. With the completion of this work the harbor had a depth of 12 feet at low water over about 6 acres of its area, except in a small place where the presence of rock in place limited the depth to a little les than 12 feet.

IMPROVEMENT OF SHOALS IN ST. LAWRENCE RIVER, AND OGDENSBURG

HARBOR, NEW YORK, AND OF RIVERS AND HARBORS ON LAKE CHAMPLAIN, NEW YORK AND VERMONT.

Officer in charge, Maj. M. B. Adams, Corps of Engineers; Division Engineer, Col. Henry L. Abbot, Corps of Engineers.

1. Shoals between Sister Islands and Crossover Light, St. Lawrence River, New York. The act of August 11, 1888, provided for a survey of the shoals between Sister Islands and Crossover Light, in the St. Lawrence River, New York, which, being made, was subinitted July 2, 1889, and printed in Report of the Chief of Engineers, 1889, pages 2463 and 2464. The entire improvement was estimated to cost $13,305.

The act of September 19, 1890, appropriated $5,000 for this improvement, which has been pledged under contract for the removal of the upper and lower shoals.

Work can be carried on most advantageously in the winter season when thick ice has formed, but as the ice did not form of sufficient thickness in the winter of 1890–91 to bear the machinery, etc., necessary in connection with such operations, the time for the completion of the contract was extended so as to include another winter, and again the ice did not become thick enough, but operations are expected to be commenced during the month of July and to be completed on time as extended, August 31, 1892.

2. Ogdensburg Harbor, New York.—The present project for the improvement of this harbor was adopted in 1890, and contemplates the deepening of the various channels leading from the deep water of the St. Lawrence River and that along the city front so as to afford a depth of 17 feet at extreme low water, at an estimated cost of $158,950.

When operativns were commenced at this harbor the channels afforded depths from 5 to 12 feet only, and now there are three good channels from deep water in the St. Lawrence River to the nearest docks or wharves, in which water 15 to 16 feet deep is afforded, and a channel 12 to 15 feet deep has been made along the city front. The appropriation of September 19, 1890, has been pledged under contract and will be consumed in deepening the channels at this harbor.

The total amount expended from the date of the first appropriation in 1852 to June 30, 1892, has been $174,449.33, and from the adoption of the project of 1832 to that of 1890 some $10,000 was expended.

3. Breakwater at Rouse Point, Lake Champlain, New York.—The project for this improvement was adopted in 1885, and contemplates the construction of a breakwater composed of rubble and large stone on a straight line from Stony, Point until the 18-foot curve in the lake is reached, a total distance of about 2,000 feet.

The estimated cost of the breakwater is $110,000. Work was commenced by contract September, 1885, and has been in progress since then. Four contracts have been worked out and resulted in the construction of some 1,700 linear feet of completed breakwater.

The good effects of the breakwater are apparent in the increased shelter afforded at the docks and wharves. July 1, 1891, balance unexpended.....

Lake Champlain to Champlain village, which being made, was sub• mitted July 3, 1889, and printed in the Report of the Chief of Engineers, 1889, page 2466.

The first estimate for the improvement of this stream provided for a least width of 50 feet, and a least depth of 6 feet, at a cost of $34,000, afterwards reduced to a channel 40 feet wide and 5 feet deep at a cost of $18,000.

The act of September 19, 1890, appropriated $10,000 for this improvement, which was placed under contract and expended in widening and deepening the channel in accordance with the project. July 1, 1891, balance unexpended

5. Breakwater at Gordon Landing, Lake Champlain, Vermont.-The project for this improvement was adopted in 1887, and has for its object the construction of a stone breakwater, composed of rubble and large

stones, extending in a straight line to the 16-foot curve in the lake, for the purpose of affording increased shelter to a landing on the west shore of Grand Isle, Lake Champlain, Vermont.

Construction commenced August 11, 1887, and was completed September 19, 1891. The structure terminated at 675 feet in length instead of 800 feet as originally contemplated. July 1, 1891, balance unexpended

6. Plattsburg Harbor, New York. The first appropriation for the improvement of this harbor was in 1836.

The project then adopted and the modifications that have been made since have resulted in the construction of 1,550 linear feet of breakwater, the protection of a portion of the beach, and the dredging of some shoal areas within the harbor.

Under the appropriation of September 19, 1890, amounting to $32,500, proposals were invited and a contract made for repairing the superstructure of the existing breakwater and for prolonging the breakwater 300 feet northward.

Operations are in progress, but the contract does not require completion until November, 1892.

The total amount expended at this harbor to June 30, 1892, has been $170,404.67, of which amount $82,224.66 was expended since the adoption of the modified project of 1870. July 1, 1891, balance unexpended

7. Burlington Harbor, Vermont.—This improvement dates from 1836; modifications of the original plan have been made from time to time so as to afford adequate protection to the increasing commercial and shipping interests of the harbor. The last modification, made in 1886, provides for further extension of the breakwater both to the north and to the south, with its gradual withdrawal as it is prolonged into water about 30 feet deep instead of 38 feet deep, so as to reduce the cost.

Operations during the past year consisted in the repair of 1,000 linear feet of the breakwater superstructure under contract for the material and by hired labor.

The balance of the appropriation of September 19, 1890, $15,759.89, will be expended in repairs as needed.

The total amount expended to date has been $566,162.31, and under the existing project, $59,580.19. July 1, 1891, balance unexpended
