We reconstruct 472 years of moisture availability for the NYC watershed to place these emergencies in long-term hydroclimatic context. Using nested reconstruction techniques, 32 tree-ring chronologies comprised of 12 species account for up to 66.2% of the average May-August Palmer Drought Severity Index. Verification statistics indicate good statistical skill from 1531-2003. The use of multiple tree species, including rarely-used species that can sometimes occur on mesic sites like Liriodendron tulipifera, Betula lenta and Carya spp., seems to aid reconstruction skill. Importantly, the reconstruction captures pluvial events in the instrumental record nearly as well as drought events and is significantly correlated to precipitation over much of the northeastern US. While the mid-1960s drought is a severe drought in the context of the new reconstruction, the region experienced repeated droughts of similar intensity, but greater duration during the 16th and 17th centuries. The full record reveals a trend towards more pluvial conditions since ca 1800 that is accentuated by an unprecedented, 43-year pluvial event that continues through 2011. In the context of the current pluvial, decreasing water usage, but increasing extra-urban pressures, it appears that the water supply system for the greater NYC region could be severely stressed if the current water boom shifts towards hydroclimatic regimes like the 16th and 17th centuries. STUDY NOTES: This collection of QUVE raw ring widths was made by N. Pederson # on the west-facing slopes on the east side of Lake George # in Hague, NY. These data were collected for a dendroecological # study of southern temperate trees growing at or near a northern # range margin. While the oldest trees in the stand were targeted, # the goal of field sampling was to collect a range of existing # tree ages within the stand. The stand in which they are sampled # has a wide range of soil depth. At the time of sampling, # the forest was fairly dense. Detrending of these raw data # with closed-canopy or forest interior conditions in mind # should be considered. # # The raw data in this collection contains values of -8888 # for years where the rings were distorted or otherwise not # useful for dendroclimatology. The latest version of ARSTAN # reads these as dummy variables and can in-fill these gaps. # NOAA Template Raw Measurements file added 2019-02-08.
