The British Ambassador to the Secretary of State

No. 147

Sir: With reference to my note No. 144 of the 24th instant I have the honour to forward to you, herewith, copies of two reports made to the Canadian Deputy Minister of Public Works which more fully explain existing conditions which gave rise to the complaint of the Mayor of Warroad respecting the height of the water in the harbour of that town.

It will be observed that the conditions obtaining are abnormal, that all regulation works are wide open but that lake elevations are still rising. It appears that nothing can be done until these conditions abate.

I have [etc.]

The Engineer of the Upper St. Lawrence District to the Deputy Minister, Department of Public Works, of Canada

Dear Sir: I beg to acquaint you with the following memoranda with regard to water conditions over the Lake of the Woods tributary waters.

This office is in daily communication by night telegram with the Fort Frances office during the present period of excessive high water, most particularly for the benefit of the Lake of the Woods Technical Board and the International Joint Commission.

Namakan Lake is tributary to Rainy Lake and its waters are controlled by Kettle Falls by masonry dams owned by the Minnesota & Ontario Power Co., and the Ontario & Minnesota Power Co., of International Falls, Minnesota and Fort Frances, Ont.

The control is by stop log sluice ways. The plans of the dams, and as they are built, were approved by the Department of Public Works in 1914, one of the conditions of approval being as follows:—

That the company agree that the control of the flow past the section shah be regulated solely by such officers or persons as may be hereafter appointed for the purpose by the Minister of Public Works, and that, in case of any difference of opinion, the ruling of the Minister of Public Works for Canada shall prevail.

In accordance with this clause, Mr. S. J. Chapleau, District Engineer of the Department of Public Works, was authorized to arrange for the control of the flow and, after consultation with the United States engineers and other parties if necessary, to fix the [Page 303] extreme high-water level. Following this, an arrangement was made and agreed to between Mr. Chapleau as representing the Dominion Department Of Public Works, and Col. C. L. Potter, of the Corps of Engineers, representing the United States interests, whereby the high limit of lake regulation was fixed at elevation 508.5, subject to reconsideration by either Government or by the International Joint Commission.

This secures a regulation between 508.5 and the 497 or lower, should Rainy Lake be drawn down.

Extraordinary high water conditions prevail over the whole of the northern waters catch basins east of Manitoba at the present time to such an extent that even with the control wide open lake elevations are still rising.

Please note the following copy of wire received from Fort Frances this morning.

Namakan elevation yesterday 510.90 and rising three inches per day, all sluices Namakan dam being opened to-day. Rainy Lake yesterday 498.15, upper 496.80, lower 472.50, discharge 23,721 second feet. Rainy Lake to-day 498.25, upper 497.00, lower 492.55, discharge about 24,500 water flowing over dam.

This telegram has been communicated to the International Joint Commission.

Nothing more can be done to reduce the abnormal high water; Namakan Lake, Rainy Lake and Lake of the Woods are filled beyond their capacity and all regulation works are wide open.

The Hydrographic Survey to the Deputy Minister of Public Works of Canada

Sir: Over the telephone this morning I had a conversation with Mr. Chapleau, at Kingston, and he is worrying quite a lot over the condition of the water in Rainy and Namakan Lakes, in the Lake of the Woods District and he asked me to have some talk with you over the matter, but unfortunately you were very busy this morning and I have just learned that I cannot get in touch with you this afternoon before I leave for Montreal.

The fact is the whole district is inundated at the present time, all the lakes and reservoirs are full to overflowing and there is no place to store any water; the International Joint Commission and the Technical Board are worrying as well as Mr. Chapleau. The Lake of the Woods outlet is as wide open as it can be made and still the water in the Lake is rising; Rainy Lake is discharging 2½ times its mean flow, rather more than Lake of the Woods can take care of; Namakan Lake is full and flowing 2 ft. over the top of the dam at the outlet, so that there is nothing that ether Mr. Chapleau or the rest of us can do until conditions abate.

I dare say you are aware that there was an unusually heavy snow fall in that district during the past winter and there have been some pretty heavy rain storms this spring. You will remember that there was a complaint about flood condition in the Rosseau and Red Rivers, this is part of the same district and there seems little to do.
