Great Salt Lake Basin Watershed Boundaries Shapefile

Shapefile giving geographic boundaries of the Great Salt Lake Basins. There are 6 features in this shapefile
- The lake itself. This is at a nominal high extent as extracted from common data sources
- Bear River Basin
- Weber River Basin (Which includes Davis County)
- Jordan/Provo River River Basin
- West Desert
- Strawberry

Strawberry is not topographically within the Great Salt Lake drainage, but is the area draining to Strawberry reservoir that supplies water to the GSL basin through the central Utah Project.

The west desert was delineated from digital elevation model analysis separating out the area more adjacent to the lake from a larger area that extends much further south but deemed not relevant for Great Salt Lake hydrology studies.

The original source of this data is not known. For a more precise and current basin delineation I suggest referring to the USGS watershed boundary dataset. This data is the underling data for maps in the following papers

本数据集为美国大盐湖流域地理边界之 Shapefile 格式文件。其中包含六项特征：
- 大盐湖本身，其范围基于从通用数据源提取的标称高程。
- 贝尔河盆地。
- 韦伯河盆地（包括戴维斯县）。
- 约旦/普罗沃河盆地。
- 西部沙漠。
- 斯特拉瓦莓。
斯特拉瓦莓地形上并不位于大盐湖排水区内，但其流域区域汇入斯特拉瓦莓水库，通过犹他州中央项目为 大盐湖流域提供水源。
西部沙漠通过数字高程模型分析进行划界，将更靠近湖泊的区域与向南延伸更远的较大区域区分开来，后者被认为与大盐湖水文研究无关。
本数据集的原始来源不明。若需更精确和最新的流域划界信息，建议参考美国地质调查局（USGS）的流域边界数据集。本数据集为以下论文中的地图提供基础数据：
