1921-22 DEPARTMENT OF LANDS AND FORESTS 



The river was very low in August, when the survey was made, which made 

 the work much easier. In high water, the flow would be very rapid. There 

 are numerous rapids and a few falls. The most important rapids are the 

 Five and One-Half Mile rapids, in the townships of Strachan and Montcalm, 

 and the Ten Mile rapid, from Station 17 in the township of Hicks, through 

 Stringer, to Station 13, township of McVicar. The total fall of the first is 

 eighty-five feet, and that of the latter about the same, the Ten Mile rapids 

 being much flatter. Canoes can be poled or tracked nearly all the way up 

 both rapids, there being three lift-overs in each. 



The Pishkanogami River flows into the Groundhog from the west, between 

 Stations 23 and 24, in the township of Montcalm- At its mouth it is only about 

 one and one-half chains wide. The banks are very steep and densely timbered. 

 Cedar grows very thickly and overhanging the stream. 



The Natt River empties into the Groundhog at Station 17 in Poulett 

 township. It runs parallel and can be used for a canoe route when the Groundhog 

 is high, to overcome the Five and One-Half Mile Rapids. Its width is from 

 one to one and one-half chains. 



Waterpowers on Groundhog River. — There are two powers which can be 

 developed without extremely long penstocks for dams. The first is at Station 

 11 in Reeves Township and has a fall of eighteen feet. The flow measurement 

 was made on August 22nd, 1920, but is away below average for the year, and is 

 not a fair estimate. At this time it was 832.4 cubic feet per second. 



The second power is somewhat better, having a fall of twenty-seven feet. 

 It is located between Stations 6 and 8 in Melrose township. I did not measure 

 the flow here, but would say 900 cubic feet per second, or practically 10 per cent, 

 greater than the first falls would be about right for conditions at that time. 



In both cases, the present head can be raised from five to ten feet without 

 serious damage to lands upstream. 



(c) Kapnskasinf River. — The survey of the Kapuskasing River was com- 

 menced at the north boundary of Kapuskasing township and continued through 

 the townships of Amundsen, Davin, Buchan, Clouston, Allenby, Maude, Con- 

 cobar and Shaney. 



Kapuskasing River has a width of about three and one-half chains at the 

 north boundary of Kapuskasing township, and carries this width through to 

 slightly north of the north boundary of Allenby. Through Concobar and 

 Shaney the width increases to almost seven chains on the north boundary of 

 Shaney. 



The banks, with the exception of where rapids are shown, and at one or 

 two points, are low, with a width of from ten to twenty chains where the ground 

 rises to the average height of the country, say probably, one hundred and fifty 

 feet above the river. 



Timber. — The river is practically free from brules and the timber is nearly 

 the same through the whole length surveyed, being cedar up to ten inches, 

 poplar up to twelve, spruce from four to twelve, with some small balsam. There 

 is the odd jack pine, but none of any great importance. 



Waterpowers. — The most important power on the portion of the Kapus- 

 kasing surveyed is just north of the line between Buchan and Davin townships, 

 between Stations 3 and 6. The falls itself measures 16 feet, but the total fall, 

 including the rapids, is 33 feet. 



The next is a falls of 10 feet in the township of Shaney, at Station 17. There 

 are no others of importance.
