IMPROVEMENT OF MISSISSIPPI RIVER ABOVE FALLS OF ST. ANTHONY, MINNESOTA: OF CHIPPEWA RIVER, WISCONSIN; OF ST. CROIX RIVER, WISCONSIN AND MINNESOTA; OF MINNESOTA RIVER, MINNESOTA, AND OF RED RIVER OF THE NORTH, MINNESOTA AND NORTH DAKOTA; GAUGING MISSISSIPPI RIVER AT OR NEAR ST. PAUL MINNESOTA.

1. Mississippi River ahore Falls of St. Anthony, Minnesota.-The present project, adopted in 1880, consists in the improvement of the river between Aitkin and Grand Rapids, a distance of 130 miles, by removal of snags, bowlders, bars, and leaning trees from the channels and construction of wing dams where necessary to afford 3 feet depth at lowwater stage, the cost being estimated at $54,127. In 1889 the estimate was increased to $63,000. Under the appropriations of 1880, 1881, and 1882, the river between the points named was well cleared of large numbers of obstructions. But between 1884 and 1888, and during the flood of the latter year, large numbers of snags and overhanging trees were formed.

The appropriation of $10,000 made by act of August 11, 1888, was applied to removal of obstructions between Grand Rapids and a point about half way to Aitkin, and in addition a number of bowlders were removed to within 20 miles of the latter point.

Before improvement commenced in 1880, the stream between Aitkin and Grand Rapids was so obstructed that navigation was difficult and at times almost impossible for steamers of lightest draft.

This appropriation was made for improving Mississippi River between Minneapolis and mouth of Missouri River.

For continuing work between Minneapolis and mouth of Missouri River.

Total expended under present project to June 30, 1891, including outstanding liabilities, $55,439.35.

There was then a general depth in the improved channels of 3 feet at low water. A few snags and leaning trees offered some obstruction, but did not seriously interfere with navigation.

During July, August, and September, 1891, work was carried on in removing snags and leaning trees between Grand Rapids and Aitken. For a number of years previous to the present season several steamers have navigated this portion of the Mississippi, carrying passengers and freight to the settlements and supplies for lumber camps.

The opening, during the winter of 1889-'90, of the Duluth and Winnipeg Railroad, from Duluth to the Mississippi River, resulted in one steamer being withdrawn from the freight and passenger business, though at the beginning of the season of 1891 she was again put into commission.

2. Reservoirs at headwaters of Mississippi River.-The object of the reservoirs is to collect surplus water, principally from the precipitation of winter, spring, and early summer, to be systematically released so as to benefit navigation upon the Mississippi River below the dams. The reservoir project is the outcome of surveys and examinations made in 1869, 1874, 1878, and 1879. From the results of these examinations and further examinations made in 1880 the first cost of constructing reservoir dams in Minnesota and Wisconsin was placed at $1,809,083. The cost of land and other damages to result from construction and operation of the proposed dams was not included in that estimate, as they could not be predicted with any approach to accuracy.

The present project consists in constructing reservoir dams at the head waters of the Mississippi River in Minnesota, that locality having been selected for commencing the work, in consequence of an appropriation made by the river and harbor act approved June 14, 1880, for construction of a reservoir dam at Lake Winnibigoshish, Minnesota, and for other reasons, given in Appendix Y to the Annual Report for 1886. By 1886 four of the reservoirs had been created. During May and June, 1891, men and materials were assembled for the construction of a fifth reservoir at Sandy Lake.

Total expended on this work to the close of the fiscal year ending June 30, 1891, including examinations at proposed dam sites, land damages, amounts paid to commissioners in attempted settlement of awards to Indians, and care and maintenance of the works, $619,850.20.

During the past year the operations have been: Operating completed reservoir, continuing construction of Sandy Lake Dam, and acquiring title to lands, by condemnation proceedings, that will be subject to overflow by the Sandy Lake Dam.

The reservoirs were operated 1885-'91, during the seasons of low water, to the benefit of navigation on more than 165 miles of the Mississippi River, viz, between Grand Rapids and Aitkin, 1304 miles, and from St. Paul to some distance below the confluence of the Missisippi and St. Croix rivers.

Ricer, Wisconsin and Minnesota.-The original project for adopted in 1878, was based upon a survey made in 1874, er was at a high stage of water and but comparatively few to be seen. It contemplated removal of snags, bowlders, tc., and contraction of the low-water channels from Taylor confluence of the river with the Mississippi into one of rm width. Estimated cost, $21,758. At low water, howannel had in many places but 2 feet depth, and steamers . made their way as best they could amongst the obstrucimes it was impossible for them to get over the shoal places. at project, adopted in 1880, and modified as to cost in 1882, 1 in 1889, is based upon a low-water survey made in 1879, and m that originally adopted only in amount of work to be done. d cost, $108,700.

effect of the work of improvement has been to secure a least of 3 feet on the improved bars above Stillwater and 4 to 5 feet e bars below that place. Generally it may be said of this imment that at many points navigation has been rendered permawhere formerly it was uncertain, and that in other places it has made practicable where before improvement it was impossible. the improved parts of the river above Stillwater there is a lower depth in the channel of 2 feet; below Stillwater there is a good nnel with a least depth of 4 feet.

The work of improvement during the last year has consisted in dening the channel over the Hudson Bar by dredging, in removing ags and sunken logs, and making minor repairs to Log House Dam. The work at Hudson enabled the raft boats, with their large tows, to more easily make the run over the bar.

5. Minnesota River, Minnesota. From 1867 to 1873 Congress appropriated $77,500 for improving the Minnesota River. The appropriations were applied to removing snags and bowlders, so as to afford a least depth at low-water stage of 2 to 3 feet. In 1874 a survey was made from the mouth of the river to South Bend, a distance of about 116 miles, to determine the practicability of improving the navigation by means of canals, locks, and dams. Based upon this survey, estimates were made for five locks and dams and removal of snags, etc., at a cost of $733,868.63, the cost of removing snags, etc., being therein placed at $34,585.10, including contingencies. Following this report, Congress made three appropriations, of $10,000 each by acts approved March 3, 1875, August 14, 1876, and June 18, 1878, which sums were applied to clearing the river of obstructions below South Bend. Expended to June 30, 1879, $117,457.

Since 1879 no work for the improvement of the river has been undertaken. Under the appropriations above named the removal of obstructions cleared the way over long stretches of the river between Minnesota Falls and a point about 30 miles below Henderson (16.7 miles above Shakopee). Little or no use was made of the cleared channels, as there was not sufficient water in the channel to permit navigation during the low-water periods. The rapidly caving banks on the upper section of this stream cause snags and leaning trees to form, so that channels that were cleared of them 12 years ago are more or less encumbered with them to-day.

No expenditures have been made for the improvement of the lower part of the river, which affords much better facilities for river traffic than the upper part.

From Shakopee to the Mississippi the river is deep except on two bars. There are few snags on this reach.

The river and harbor act of August 11, 1888, appropriated $10,000 for improving the Minnesota River, including protection of the banks opposite the borough of Belle Plaine. It appearing from an examinafon made in September, 1888, that the sum was inadequate for the purposes named, its expenditure for work of improvement was deferred war the further wishes of Congress in the matter might be known. Total expended on the improvement of the whole river to the close of the tiscal year ending June 30, 1891, $117,532.
