11. Presence of pools and side holes as places of shelter 

 for fish. 



12. The kinds of fish present. 



13. As much local information as possible should be 



obtained regarding the extent to which a stream 

 is fished and the agencies available for carrying on 

 systematic stocking and development, giving name 

 of clubs or names of reliable individuals who would 

 attend to planting of fry. 



14. What part of water is diverted for irrigation. 



With such information available your Commission could make a more fair 

 distribution of fry than can now be done, when reliance is placed upon individual 

 applications, with only a fragmentary report upon the waters to be stocked. It 

 would also be possible to, in this way, prevent overstocking streams as 

 well as to avoid planting unsuitable varieties, and also to keep track of results 

 obtained. 



Three Best Varieties. 



Our experience in planting the Eastern Brook trout, as one instance, con- 

 vinces us that while this fish in its native haunts flourished best in streams fed 

 by springs and having a rapid flow over gravelly bottoms, when planted 

 in Mountain waters better results are obtained from planting made in lakes.

sloughs, ponds, or other waters having little flow and often with muddy bottom. 

 Careful observation has convinced your Commission, and we so report that the 

 native, black spotted or cut-throat trout (Salmo Clarki) the grayling (Thymallus) 

 and the rainbow trout (Salmo Iredeus) are the three varieties best suited to our 

 lakes and streams. While it is claimed by some that the rainbow trout is de- 

 structive to the other species mentioned it is certain that in most of the streams 

 flowing to the Pacific both the rainbow and black spotted trout are native to 

 the same waters, and we are not yet convinced that the rainbow trout are 

 destructive to the grayling, because of conditions in Madison River. 



All efforts to stock the streams flowing to the Pacific with grayling have so 

 far failed. In three lakes, the outlets of which flow to the Pacific, the grayling 

 has flourish<Ml, that is, in (leorgftown lake, where the growth has been remark- 

 able, in (lie Little Pitter Hoot laki\ near Kalispell, and in a small land-locked 

 lake on the Clear Water river in Missoula County. In the last named lake the 

 fish planted grew to a good size and were then killed by the freezing of the
