The 2012-2015 drought was an exceptional period of warm and dry weather that impacted water and ecological resources in the Lake Tahoe Basin (LTB). Although above average temperature and below average precipitation occurred in all four years, the patterns varied across years and in different parts of the LTB. Water year (WY) 2012 and 2015 were the most exceptional in terms of below average precipitation (30 and 36% below the long term average, respectively). In general the southern end and higher elevations of the LTB experienced the warmest drought. Overall Palmer Drought Severity Index (PDSI) was less severe than during 1987-1990 drought.

| 07/20/2018 11:47 AM | Dan Segan | Key findings: • Drought effects on precipitation deficit and increased evaporative demand are likely to be uneven across the LTB, leading to uneven drought response. We need spatially resolved drought trackers that are more appropriate for mountain systems. • Forest health is likely to negatively respond to reductions in precipitation and increased evaporative demand. Drought trackers of forest must consider evaporative demand. • Meadows are sensitive to precipitation, but also hydrological measures related to streamflow and groundwater. Predicting meadow health under drought requires considering local groundwater flows and stores, and not just climate. Stream low flows (a measure of groundwater storage) were not strongly affected until 2015, showing a much slower response time than the ecological systems. Thresholds causing rapid declines in streamflow after multiple years of drought are a risk in the LTB. |
