To help address these concerns, ground- and surface-water conditions in the area before and during the population growth that started in the 1970s was evaluated. This dataset denotes the boundary for ground-water analysis relating to 2006 hydrologic conditions of the unconfined aquifer. Four of the tributary canyons outlined by this boundary were not included in ground-water analysis for pre-development conditions due to lack of pre-development data in these areas. This dataset represents the ground-water study area boundary for the 2006 hydrologic conditions. 2007 publication date Complete None planned -114.429618 -114.048136 43.786699 43.297905 USGS Thesaurus Water-resource trends hydrologic conditions inlandWaters ISO 19115 Topic Category inlandWaters aquifer USGS Metadata Identifier USGS:e7e3627a-0645-4cdf-8cc3-2619d9ec0a90 Geographic Names Information System Idaho Wood River Valley Blaine County Ketchum Sun Valley Hailey Bellevue Picabo Gannett None.

Unconfined aquifer boundaries were visually evaluated and reviewed to be hydrologically consistent and correct. The study area boundary was defined by using a DEM converted to a slope model to determine the transition from the adjacent bedrock hills (high slope values) to the flat portions of the valley filled with unconsolidated sediment (low slope values). This transition represents the approximate location of the boundary between the unconfined aquifer and the adjacent bedrock in the tributary canyons and the main valley.
