about 6,200 to over 13,000 feet, and 

 much of the area is above timberline 

 (11,000 feet). The predominant tree 

 cover is lodgepole pine and there are 

 lesser amounts of Engelmann spruce, 

 Douglas -fir, and subal pine fir. Many 

 aspen stands grow among these conif- 

 erous forests. Alpine meadows are 

 numerous and give way to tundra above 

 timberline . Low willows are common 

 in the meadows and along streams. 

 At lower elevations, ponderosa pine, 

 pinyon pine, juniper, and sagebrush 

 are found. 



Few roads currently penetrate 

 the North Slope. A much enlarged 

 road network is planned outside the 

 roadless High Uintas Primitive Area. 

 Thus many remote streams and lakes 

 may suddenly become accessible to 

 large numbers of people, creating a 

 need for an inventory of available 

 recreation resources and plans for 

 their development. 



This paper describes the tech- 

 niques used in the test survey and 

 makes general recommendations. 

 Wherever possible, evaluations of 

 accuracy of --and estimates of time 

 consumed by- -the various operations 

 are given. 



PRELIMINARY PROCEDURES 



To be successful, a water resource inventory using aerial photographs must be planned 

 and organized to make the best use of available funds and manpower . The amount and kind of 

 detail to be collected must be decided upon. Selection and training of the photo interpreter re- 

 quire a varying amount of advance preparation, depending on the level of intensity of the study. 



THE DRAINAGE BASIN UNIT 



Figure 1. - -Location of study area. 



The drainage patterns of mountains greatly influence the development of timber and other 

 resources, as well as water. Water resource data are most useful to administrators when 

 mapped and presented by units that correspond to drainage basins. The acreage included in any 

 particular drainage unit is not of great importance, but the unit boundaries should coincide as 

 nearly as possible with the boundaries of working units established for timber, forage, and other 

 resources. This organization allows comparison of resource values common to a specific area. 

 Fishery biologists, foresters, water engineers, highway planners, and land managers can adjust 

 their specific development plans to avoid damaging other resources .
