For the most part, the level of detail c.no relicioility of sources wore aoequdtc. 

 River seyi.ients v/ere plotted accurately on 1:100, UOO maps, but in many instances 

 references are given to sources describing the site in much greater detail — often at 

 a scale of 1:24,000. Pa I eonto logical sites were only located to the nearest township 

 in orcer to avoid aisturbance of these sensitive features. 



In general, data on natural features were far less available and 

 for eastern liontana than western. In particular. The areas within a 



less rel iable

of Bozeiiian and Missoula are the r.iost thoroughly stuciea parts of the stata; data 

 availability falls off with distance froM these centers and appears to roach a 

 ininiiiium in the northeastern corner of the state.

The data gathered here are suitable for fist- level screening of sites for siting 

 ano planning purposes. However, this prel ii.ii nary inventory is cased entirely on 

 interviews with know ledgeaol e persons and on review of certain existing publ ishea 

 data and does not constitute a coiiiprehensive study acquired for hydro power siting. 

 No field inventory, stuoy of USGS quadrangle i,iaps, or study of aerial photography was 

 conducted. . iore intensive stuay will reveal uiany adaitional sites, ana i.iany river 

 reaches i.iay ue found upon closer study to contain nigh value natural features. Tiu- 

 value class assignments, while based on syster.iatic application of the criteria anc 

 stanaaras defined in the study plan, are subjective and represent the judgment of 

 DNRC project staff subject to review by designated representatives of i3Li-i and the 

 USPS. !;'hile the r.iaps may be used as a planning tool, users are advised to consult 

 tiie final report before making decisions on the basis of this inventory.
