 CN Memo- 2 3 



If a point fell on a farm pond of 2 acres or less, the area was con- 

 sidered to be part of a facility to the land use on which the point 

 fell, such as pasture or forest. If the point fell exactly on a 

 mapping unit boundary, the point was interpreted as being, first, the 

 land immediately above or, second, the land immediately tu the right 

 of the line on which the point fell. 



Conservationists used a similar process for determining conservation 

 treatment needs. In their determinations, they followed local techni- 

 cal guides, the prevailing agricultural operations on the land, and a 

 practical system of conservation farming. 



No overlapping of acreages is shou'n as to types of treatment required 

 or still needed for the land. 



For forest land, treatment needs were estimated for commercial and non- 

 commercial land categories for counties. These estimates were based 

 on forest survey data supplied by Forest Service experiment stations 

 and on other information available. Conservation treatment needs for 

 other land were estimated based on local knowledge of conditions in 

 the county. 



The Department CNI Committee developed the policies, procedures, and 

 national economic assumptions under which the inventory was made. It 

 furnished guidance so the inventory would be compatible with intentories 

 for other states, and it has reviewed and accepted the data on which 

 this report is based. The Montana CNI committees acted in a similar 

 capacity with the county CNI committees. 



A county CNI committee with agency representation similar to that of 

 the State Needs Committee developed the inventory for each county. 

 After review and acceptance, data from county inventories were com- 

 bined to form the State inventory. 



Watershed Projects Inventory 



The revision of the Watershed Projects Inventory drew heavily on ex- 

 perience gained through several years of operation under the PL-566 

 Watershed Protection and Flood Prevention Program. Insofar as possible, 

 information was collected in conjuntioa with river basin investigations, 

 updating the land use and treatment needs phase of the inventory, and 

 other studies as appropriate. Pertinent data within and outside the 

 Department were considered. No special detailed surveys were made.
