CW DMAG Update - August 1, 2006 Low Inflow Protocol (LIP) Drought Indicators

The following are the Low Inflow Protocol (LIP) drought indicators as of the end of July 31, 2006:

Storage Indicator (SI):
Storage Index=             67.58%
Target Storage Index=    75%
Ratio=                          90.11% (Supports Stage 0)

Streamflow Indicator (six-month average versus historical six-month average):

Ratio=                          54.4% (Supports Stage 3)

US Drought Monitor (three-month average):
Three-month Numeric Average= 1.33 (Supports Stage 1)

Since the C-W Basin was in a Stage 1 at the end of June, 2006, and all indicators have to recover to move back up to the lower Stage, the C-W basin is still solidly in a Stage 1. The storage indicator is slowly deteriorating due to low inflow and the streamflow indicator continues to reflect very low inflow into the reservoirs. The Drought Monitor three-month rolling average somewhat reflects the June reading.
