Download Report - Water Sustainability Program

Seventeen multiyear sequences of past streamflow covering different time frames (30-year, 20year, 11-year, and 7-year) were selected from the reconstruction data for possible use by water
mangers in exploratory scenario development and planning for future drought conditions. An
effort was made to select sequences that represent the full range of past (and possible future)
streamflow behaviors, including severe and sustained low flow sequences, high flow episodes,
and periods with high amplitude variability. The sequences are displayed with suggestions for
how they might be used as input for projective and prospective exploratory scenarios. A
Streamflow Sequence Data Spreadsheet is available for downloading and contains the
reconstructed flow data, quantile visualizations, and graphs for each sequence. Users can use the
spreadsheet to select, plot, and/or analyze additional sequences if desired.
Ongoing and future collaborations with water managers will provide the opportunity to evaluate
the usability and applicability of this framework for drought scenario development. This
webpage can be expanded to meet the needs of the EVWF in their examination of various
management scenarios under drought conditions.
