Alpine Lake Fish Inventory in GRTE - 2002

Effective long-term management and stewardship of natural resources in the Greater Yellowstone Network begins with baseline knowledge of these resources. To acquire this knowledge, an inventory program was established by the National Park Service with the goals of acquiring baseline information for a variety of resources, from bibliographic information to species occurrence and distribution.

The twelve basic inventories are defined in appendix A of the Natural Resources Inventory and Monitoring Guidelines (NPS-75). The inventories represent important baseline information about each park's biological, physical, and information resources, all of which support the management and administration of parks and the design and implementation of a long-term monitoring program.

Water Body Location and Classification Select a park from the NPS Hydrographic and Impairment Statistics (HIS) database too view summary statistics of surface hydrography (acres of lakes, miles of streams, etc.) within and adjacent to the selected park. HIS database.

The National Hydrography Dataset, managed by the U.S. Geological Survey, contains surface water features for parks and can be viewed and downloaded using a variety of tools available on the NHD website.

National Wetland Inventory features are developed and maintained separately by the U.S. Fish & Wildlife Service for viewing and download on the NWI Web Site.
