66 REPORT OF THE No. 3 



rocks showing exposures of magnetite banded with siHca, and at one or two 

 points some diamond drilHng has been done. One of these drill holes was 

 tied to transit station No. 739, which is about four miles south along the west 

 shore from the outk;t of the lake. Drill cores were also seen on the west shore 

 near transit station No. 748. 



The north, east and south shores of Little Shallow Lake are generally 

 low and flat and in many cases no distinct shore line exists, and a foot or two 

 difference in elevation of the water of the lake would submerge considerable 

 areas that were comparatively dry at the time the survey was made. 



About three-quarters of a mile east of the outlet of Little Shallow Lake a 

 river about two chains wide at its mouth enters a shallow marshy bay. This 

 river was traversed for a distance of over seven miles and a half where it divided 

 into two branches. At this point the river is about half a chain wide and flows 

 with a gentle current through clay banks about ten to twelve feet high. The 

 country along the lower stretches of this river is very low with areas of grass 

 and willows studded with clumps of poplar. In one or two places, however, 

 high rock ridges are visible not far back. The banks of this river gradually 

 get higher as one goes up stream. There are some areas of poplar and spruce 

 of good size to be seen along the stream, but a considerable area has been burnt. 



Trout Lake River enters Little Shallow Lake in a marshy bay on the east 

 side. The shore line here is so indefinite and the bay so full of weeds and rushes 

 that it is difficult to distinguish the mouth of the river until one is right into it. 

 This is a much larger stream than the one just described, but the general char- 

 acteristics of the banks as regards elevation, soil, and timber are about the same. 

 The survey was carried up Trout Lake River, a distance of a little over ten 

 miles to the first portage, where a substantial post marked "P. No. 50" was 

 planted in a stone mound on the north side of the river. 



The territory described so far in this report appears to be largely a clay 

 country, and there is a considerable area of good agricultural land on both sides 

 of the English River and Mattawa River and east of Shallow Lake and adjacent 

 to Little Shallow Lake and the streams tributary to it. It is difficult to say 

 how extensive this clay area is, but it is undoubtedly large enough to warrant 

 further exploration. 



A most important feature affecting a large portion of this whole area, 

 however, is the fact that at times the English River and tributary waters are 

 subject to very serious flooding. This appears to be caused by the fact that 

 at Manitou Chute the English River is less than a chain wide and the gorge 

 through which the river rushes is of such a character that the water is held 

 back and rises many feet during the freshet season. On Shallow Lake and 

 Little Shallow Lake the extreme high water mark as shown on the rocks along 

 the shore is over twelve feet above the level of the lakes at the time this survey 

 was made. Such a flood occurs only occasionally but when it does occur, owing 

 to the low nature of much of the country, large areas are completely submerged. 

 Had such a freshet or one anywhere near like it occurred during the season 

 of 1922, it would have been impossible to have carried on this survey until it 

 subsided. 



In view of these facts any proposal for water power development which 

 would necessitate the raising of the waters of Shallow and Little Shallow Lakes, 

 such as a concentration of all the available fall on the English River between 

 Lac Seul and Manitou Falls at Manitou Falls, would require careful examination 

 in order to estimate the amount of damage that would be done by flooding. 



From Manitou Falls the English River runs west for about three miles
