The Sierra Wildfire Wire Detailed Fire Map has many layers of information available. An explanation of each of those layers is below.  A brief tutorial on the detailed map is available here.

FIRE Information

  • The InciWeb Incidents for California layer shows fires that federal officials (USFS, BLM, or the National Park Service) are actively responding to or monitoring.
  • The CalFIRE Incidents layer shows fires that state officials (CALFIRE) are actively responding to or monitoring.
  • The two MODIS Thermal layers show fire perimeter. This information is updated daily based upon input from incident intelligence sources, GPS data, and infrared (IR) imagery.
  • The California Fire Perimeters By Decade layer shows fire history as far back as 1878.
  • The Wildland Fire Potential 2013 layer shows the relative potential for wildfire that would be difficult to suppress based on past fire occurrence, fuel levels, and 2012 estimates of wildfire likelihood and intensity.   Areas with higher Wildland Fire Potential values represent fuels with a higher probability of experiencing high-intensity fire with torching, crowning, and other forms of extreme fire behavior under conducive weather conditions.
  • The NOAA Weather Warnings, Watches, Advisories, and Statements layer shows current weather warnings and advisories from the National Oceanic and Atmospheric Administration.

Water Information

  • The Lakes and Rivers layers show major water bodies flowing from the Sierra Nevada Region.
  • The Watersheds layer shows the streams, meadows, and lakes that drain into major river systems and provide more than 60% of California's developed water supply.
  • The Delta layer shows the boundary of the Sacramento-San Joaquin Delta Conservancy’s Region, and represents the lands and waterways that make up the Delta. Up to half of the water that flows into the Delta originates in the Sierra Nevada.
  • The Aqueducts layer shows California’s major aqueducts that carry water from reservoirs in the Sierra to urban water users in the Bay Area, the Central Valley, and Southern California.
  • The Downstream Water Users layer shows major urban water districts in California who receive a large portion of their water from the Sierra either through the federal Central Valley Project or the California State Water Project.

Wildlife Information

  • The CA Spotted Owl Range layer shows spotted owl habitat. The California spotted owl is considered a species of special concern by the California Department of Fish and Wildlife.
  • The Pacific Fisher Range layer shows habitat suitable for the Pacific fisher, a candidate species under the federal Endangered Species Act.

Other Information

  • The Transmission Lines layer shows major transmission lines throughout the Sierra.
  • The Sierra Nevada Conservancy Region layer shows the boundary around the 25 million acres that make up the Sierra Nevada Conservancy's Region.
  • The Ownership layer shows which lands are owned by federal, state, and private entities in the Sierra.
