CW DMAG Update - March 5, 2007 Low Inflow Protocol (LIP) Drought Indicators

The following are the Low Inflow Protocol (LIP) drought indicators as of March 5, 2007:

Storage Indicator (SI): 78.68%
Target Storage Index= 61.80%
Ratio= 127.31% (Supports Normal)

Streamflow Indicator (six-month average versus historical six-month average):
Ratio= 1.26.2% (Supports Normal)

US Drought Monitor (three-month average)
Three-month Numeric Average=-1.00 (Supports Normal)

Groundwater Gages:
USGS Langtree current reading= 17.57 ft (Normal)
USGS Linville current reading= 2.09 ft (Stage 0)
NCDWR Glen Alpine reading= 8.15 ft (Stage 0)

The C-W Basin was in a Stage 0, Low Inflow Watch at the end of January, 2007, and all indicators have to recover to move back up to a lower Stage, which they have in previous months. In order to move out of a LIP Stage to a lower Stage or Watch or Normal Stage, all groundwater gages need to recover to the lower stage also. The Langtree gage reading has recovered from a Stage 0 to a normal reading for two months, and the Linville gage reading has recovered to a Stage 0 reading. The Glen Alpine gage reading remains in a Stage 0 reading. Therefore, the LIP will remain in a Stage 0, Low Inflow Watch.
