Current Status
The current overall condition status of the Hydrology Indicator is Concern based on consideration of the four metric condition values, with a slightly higher weighting for Metrics 2 and 3. Dams and water diversions are causing hydrologic impairment (Metric 1), and across the landscape, there is low to moderate native species richness and invasive aquatic species are of considerable concern (Metric 4). The percentage of watershed burned in the last 20 years (Metric 2) is high, and impervious surfaces (Metric 3) associated with development are increasing runoff. Additional metrics may be added as more information becomes available.
