pared with maps delineatino reservoir areas, furnished much working data 

 lelative to pre-constructioii output in the Franklin Falls. Blaekvvater, and 

 Surry Mountain areas. For the MacDowell project, which was undertaken 

 in the late 1940's, such town maps could not he used at all hecause of the 

 great discrepancy in time periods. 



Types of farming data contained no mention of the crop and pasture 

 acreage associated with particular livestock immbers, nor its location. In 

 some instances, units recorded elsewhere were omitted. Some producers, 

 whose farmsteads were not physically located in area.s which were subse- 

 quently acquired, used lands in those areas. 



Livestock Numbers 



Data are collected annually by selectmen of towns and appraisers in cities 

 of New Hampshire in connection with tax listings. This information, by 

 individual farms and taxpayers, was obtained for the pre-construction period 

 and for 1953-1955, and supplemented data on types of farming maps and 

 from other sources. Individual units could be located on maps, but again 

 data on numbers of livestock furnished no estimate of acreages used or 

 their locations. 



Census Data 



Another source of information, though not used in this study because of 

 the costs and time required to obtain it, is Bureau of the Census reports 

 on individual units. Such data would furnish relatively accurate measure- 

 ments of pre-construction output in areas under consideration. It would be 

 accurate as to livestock numbers, acre*, forage production, and crop acre- 

 ages and output for individual farm units. 



However, such data would not be specific as to the location of the land 

 mvolved, and would not necessarily be conclusive enough to enable determi- 

 nation of reservoir and non-reservoir lands. In the post-construction period, 

 such a determination from Census data would be even more difficult due 

 to the .'^hift in ownership from private to public in reservoir areas. 



Output Measurement on Future Projects 



For future flood control projects, it would be possible to describe pre- and 

 post-construction output from the reservoir lands, both for crops and for 

 the livestock utilizing crops, by making farm-by-farm and tract-by-tract 

 surveys. With existing projects, it is possible to use leasing records and 

 maps of the Corps of Engineers, supplemented by data obtained from lessees, 

 to describe with some accuracy, output from reservoir lands in the post- 

 construction period. While some inaccuracies may be involved due to the 

 passage of time and the fallibilit) of memory, such estimates are probably 

 fairly accurate. 



However, to now attempt to survey all former owners, or people who knew 

 them, would be rather time-consuming. Some operators have moved from 

 the area, many might have difficulty recalling accurately the required in- 

 formation. A number of operators have died. Hence, estimates for such 

 tracts as they owned would be second-hand. In many instances, data secured 

 by contacting former owners did not check out very well against recorded
