;, 2. Character of the bottom, 

 r ; 3. Rate of flow. 



4. Color and transparency of the water. 



5. Vegetation in and along the stream and amount of shade 

 provided. , 



.-, 6. Character of the surrounding country — whether timbered or 

 open land and whether the stream is likely to be subject to drought, 

 severe floods, or the inflow of a large amount of sediment from the 

 watershed. 



7. Temperatures from source to mouth. 



8. Headwaters and spring tributaries were located as possible 

 planting points. 



- 9. Obstructions to the migration of fish. 



; 10. Points at which pollutions occurred and the character, amount, 



and general effects of the pollution. 



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



12. Streams or sections of streams posted, and by whom. 



■13. The quantity and variety of food organisms for fish in the 

 stream. 

 , 14. The kinds of fish present. 



15. A few fish were taken from each stream for future stomach 

 examination, in order to obtain more accurate data on the natural 

 fish food, 



16. As much local information as possible was obtained regarding 

 the extent to which a stream is fished and the agencies available for 

 carrying on systematic stocking and development. 



After a discussion of the " broader issues," " working plans " 

 are suggested, and detailed recommendations for streams follow. 

 The specific recommendations are very brief, consisting principally 

 6f a statement of their fitness or unfitness for fish and the kind 

 of fish to be planted in any instance. 



It was not until late in 1922 that Embody's report upon Tompkins 

 County was published. His report covers not only the streams but 

 also to some extent the lakes and ponds. General conditions 

 are discussed and more detailed consideration of each body of 

 water is given than is the case in the Oneida County report. 



Concerning " Brook Trout versus Brown and Rainbow Trout," 

 Clemens ('17) says: "It has been proved conclusively that brown 

 trout are very destructive to native brook trout. Hence in the 

 working plans following, brown trout are recommended for only 

 those river systems in which most of the water is no longer suit- 

 able for brook trout and where conditions give little promise of 

 improvement in the near future. It is important to take the entire 

 river system into consideration, and not merely individual streams, 

 for brown trout planted in one stream in the system will in time 

 work into the other streams, unless prevented 1w dams or other 

 obstructions. Rainbow trout prefer large bodies of water and show 

 a tendency to work down from the upper streams into the lakes and 

 larger streams. They are somewhat destructive to native trout and
