This model was based upon expert review, known habitat and known locations of the species. The model can be linked or joined via the "Seg_ID" to the streams layer used in this project.

The Vista tool is used to create a Scenario of the CAs affecting the North American Warm Desert Lower Montane Riparian Woodland, Shrubland and Stream CE and applies user-input Landscape Condition Model (LCM) scores to generate ESAs for each of the CEs. The LCM consists of Site Impact scores and impact Distances for each CA category. Site Impact scores are a value between 0 and 1 representing the impact of the CA on the relevant CEs. A score close to 1 indicates negligible or no impact from that CA. A score close to 0 indicates the highest possible impact, e.g. an interstate highway that makes the area in which it occurs completely unsuitable for the CE. Distances are set in meters and extend the impact of the CA...

The National Hydrography Dataset (NHD) is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the nation's surface water drainage system. NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country. This high-resolution NHD, generally developed at 1:24,000/1:12,000 scale, adds detail to the original 1:100,000-scale NHD. (Data for Alaska, Puerto Rico and the Virgin Islands was developed at high-resolution, not 1:100,000 scale.) Local resolution NHD is being developed where partners and data exist. The NHD contains reach codes for networked features, flow direction, names, and centerline representations for areal water...

This dataset provides an estimate of aquatic biodiversity sites, based on protected and conservation lands superimposed on the NHD flowlines dataset. Caution is warrented in interpreting this dataset. While measures of aquatic biodiversity exist, they are based on localized samples that cannot be extrapolated beyond the sampling domain. These measures were not included in this dataset. Instead, it was assumed that areas within TNC Portfolio areas were identified for factors that include high aquatic biodiversity. Furthermore, it is assumed that aquatic biodiversity is higher in protected areas due to stricter controls over land and water management. However, this assumption may not be valid for stream reaches that...

Active Water Rights of Montana. The data consists of estimated locations of all the active recorded points of diversion and points of use in the water rights database. There are four separate spatial layers: Points of diversion, Points of Use, Points of Reservoirs, and Points of Use for Irrigation (a subset of Points of Use). The version of this data available at the State Library is updated on a weekly basis. For administrative purposes, the original version of all active water rights is given (i.e. Version ID = 1). If change of information about a particular water right has occurred over time, there will be an additional version of the water right, and depending on how many changes, there will only be one other...
