CURRENT RESERVOIR LEVELS
A soil/duff drought index that ranges from 0 (no drought) to
800 (extreme drought) and is based on a soil capacity
of 8 inches of water. Factors in the index are maximum daily
temperature, daily precipitation, antecedent precipitation,
and annual precipitation.
- KBDI = 0 - 200: Soil moisture and large class fuel
moistures are high and do not contribute
much to fire intensity. Typical of spring dormant season
following winter precipitation.
- KBDI = 200 - 400: Typical of late spring, early growing
season. Lower litter and duff layers are
drying and beginning to contribute to fire intensity.
- KBDI = 400 - 600: Typical of late summer, early fall.
Lower litter and duff layers actively
contribute to fire intensity and will burn actively.
- KBDI = 600 - 800: Often associated with more severe
drought with increased wildfire occurrence.
Intense, deep burning fires with significant downwind spotting
can be expected. Live fuels can also
be expected to burn actively at these levels.
