This map service supports the https://www.flatheadlakers.org/ portions of the River Conditions Tool (https://uppermissouriheadwaters.org/UMHW_RiverConditions/index.html). Data was provided by the https://www.flatheadlakers.org/ for both the 1964 Flood and the Depth to Water table of the Flathead River. Leveraging the investment of the USFWS Region 6 Science Applications’ funded project Building Large Scale Drought Resiliency in the Missouri Headwaters Basin, the tool further supports stakeholders in drought management planning by improving access to US Geological Survey, Montana Fish Wildlife and Parks, and Montana Dept. of Natural Resources Conservation Services (DNRC) river condition data. In collaboration with MT DNRC, this data drives functionality similar to the River Conditions tool on the Big Hole River Conditions web page for eight basins within the Missouri Headwaters Basin. The tool is to be embedded on websites for easy access to real-time stream conditions such as temperature and flow, and river status (e.g., restrictions, closures).

The data release for the geologic and structure maps of the Kalispell 1 x 2 degrees quadrangle, Montana, and Alberta and British Columbia, is a Geologic Map Schema (GeMS)-compliant version that updates the GIS files for the geologic map published in U.S. Geological Survey (USGS) Miscellaneous Investigations Series Map I-2267 (Harrison and others, 2000). The updated digital data present the attribute tables and geospatial features (lines and polygons) in the format that meets GeMS requirements. This data release presents the geologic map as shown on the plates and captured in geospatial data for the published map. Minor errors, such as mistakes in line decoration or differences between the digital data and the map image, are corrected in this version. The database represents the geology for the 16,436 square kilometer, geologically complex Kalispell 1 x 2 degrees Quadrangle, at a publication scale of 1:250,000. The map covers primarily Flathead and Lincoln Counties, but also includes minor parts of Glacier, Lake, and Sanders Counties. These GIS data supersede those in the interpretive report: Harrison, J.E., Cressman, E.R., Whipple, J.W., Kayser, H.Z., Derkey, P.D., and EROS Data Center, 2000, Geologic and structure maps of the Kalispell 1:250,000 quadrangle, Montana, and Alberta and British Columbia: a digital database: U.S. Geological Survey Miscellaneous Investigations Series Map I-2267, version 1.0, 23 p., scale 1:250,000, https://pubs.usgs.gov/imap/i2267/.

This is a map service for the display and query of data collected between September 22 and September 29, 2009, covering the floor of the Flathead Valley above Flathead Lake, the area around Polson, and the shoreline areas of Flathead Lake, Whitefish Lake, and Swan Lake. Data from the project include natural color and color-infrared orthorectified aerial photos whose horizontal resolution is 1 foot, a digital elevation models whose resolution is 6 feet, and topographic contour lines whose interval is 2 feet. The vertical datum of the data is NAVD88, Geoid 03. The service is an ArcGIS Server Map service that may be loaded into GIS applications and used in web mapping applications.

Parcels whose legal descriptions consisted of aliquot parts of the public land survey system were created from the GCDB coordinates by selecting and, when necessary, subdividing public land survey entities. Other parcels were digitized from paper maps and the data from each map were transformed to fit with the appropriate GCDB boundaries.

The data release for the geologic and structure maps of the Wallace 1 x 2 degrees quadrangle, Montana and Idaho, is a Geologic Map Schema (GeMS)-compliant version that updates the GIS files for the geologic map published in U.S. Geological Survey (USGS) Miscellaneous Investigations Series Map I-1509-A (Harrison and others, 2000).

Tribal Nations Reservation Boundaries were digitized from the U.S. Geological Survey (USGS) 1:250,000 scale maps adjusted to be coincident with the Bureau of Land Management's Geographic Coordinate Database (GCDB) or the USGS 1:24,000 scale Digital Raster Graphics (DRGs). Where reservation boundaries are coincident with public land survey lines, they were copied from the BLM's GCDB. If boundaries were not coincident with GCDB lines, they were digitized on screen from the USGS DRGs. Reservation Boundaries will change as the GCDB is adjusted by the BLM and those data are imported into the Montana Cadastral Data Model. Montana Reservation Boundaries coincident with the BLM's GCDB or the USGS 1:24,000 scale Raster Graphics.

The Ennis 1:100,000 quadrangle lies within both the Laramide (Late Cretaceous to early Tertiary) foreland province of southwestern Montana and the northeastern margin of the middle to late Tertiary Basin and Range province.

The oldest rocks in the quadrangle are Archean high-grade gneiss, and granitic to ultramafic intrusive rocks that are as old as about 3.0 Ga. The gneiss includes a supracrustal assemblage of quartz-feldspar gneiss, amphibolite, quartzite, and biotite schist and gneiss. The basement rocks are overlain by a platform sequence of sedimentary rocks as old as Cambrian Flathead Quartzite and as young as Upper Cretaceous Livingston Group sandstones, shales, and volcanic rocks.

The Archean crystalline rocks crop out in the cores of large basement uplifts, most notably the "Madison-Gravelly arch" that includes parts of the present Tobacco Root Mountains and the Gravelly, Madison, and Gallatin Ranges. These basement uplifts or blocks were thrust westward during the Laramide orogeny over rocks as young as Upper Cretaceous. The thrusts are now exposed in the quadrangle along the western flanks of the Gravelly and Madison Ranges (the Greenhorn thrust and the Hilgard fault system, respectively). Simultaneous with the west-directed thrusting, northwest-striking, northeast-side-up reverse faults formed a parallel set across southwestern Montana; the largest of these is the Spanish Peaks fault, which cuts prominently across the Ennis quadrangle.

Beginning in late Eocene time, extensive volcanism of the Absorka Volcanic Supergroup covered large parts of the area; large remnants of the volcanic field remain in the eastern part of the quadrangle. The volcanism was concurrent with, and followed by, middle Tertiary extension. During this time, the axial zone of the "Madison-Gravelly arch," a large Laramide uplift, collapsed, forming the Madison Valley, structurally a complex down-to-the-east half graben. Basin deposits as thick as 4,500 m filled the graben.

Pleistocene glaciers sculpted the high peaks of the mountain ranges and formed the present rugged topography.

Compilation scale is 1:100,000. Geology mapped between 1988 and 1995. Compilation completed 1997. Review and revision completed 1997. Archive files prepared 1998-02.

This data was created per Lincoln Chute, the CFSA Manager, by buffering the address layer1.5 miles to represent the Wildland Urban Interface for Flathead County.

The Flathead River CMZ was completed in 2010 to provide data which could be used to identify potential future problem areas for streambank landowners, restoration opportunities, and management best practices for 24 miles of the Flathead River above its confluence with Flathead Lake. It provides potential rates of lateral river movement for the next 100 years based on analyses of historical aerial photos 1956 to 2009). The study and map are useful to land owners, planners, river restoration, and construction professionals working near the Flathead River, and others who make decisions that could be affected by river movementThe project was sponsored by the Flathead Lakers, the Montana DEQ Wetlands Program, and Montana Fish, Wildlife, and Parks. A local Technical Advisory Committee provided project oversight and included representatives from DEQ, FWP, DNRC, Flathead County Planning and Zoning, Flathead Conservation District, Flathead River Commission, and Flathead Basin Commission, and Flathead Lakers. The work was performed by Applied Geomorphology and DTM Consulting.This map was designed to support the Library's channel migration zone web site at: http://geoinfo.msl.mt.gov/Home/data/montana_channel_migration_zones/projects/flathead_river_-_old_steel_bridge_to_flathead_lake.aspx
