Climatic Area Boundaries - Northeast River Basin (2002)

This dataset contains 1:250,000-scale climatic area boundaries for the Northeast Wyoming River Basins Planning Area. These boundaries are primarily based on the 1:250,000-scale hydrologic unit code level 4 boundaries developed by the USGS. Some of the HUCs are unchanged, others have been merged, and still others have been subdivided. Where two climate stations are assigned to one feature, the stations are weighted 50-50 when determining irrigation demands (consumptive irrigation requirements, consumptive use, irrigation diversion amount, etc).
