1. Drought Response Plan Clarke County, Virginia Saving Water/Saving Money: Water Conservation in the Shenandoah Valley March 11, 2009 Alison Teetor Natural Resource Planner Drought Response Plan Clarke County, Virginia Saving Water/Saving Money: Water Conservation in the Shenandoah Valley March 11, 2009 Alison Teetor Natural Resource Planner

2. Clarke County’s Plan Primary Goals: Local cooperation, informed drought response, and public education within the County. –Drought Indicators –Drought Stages –What happens when stages are declared

3. Precipitation Deficits Streamflow Statistics Ground-Water Levels Reservoir Storage http://www.deq.virginia.gov/waterresources/droughttac.html Virginia Drought Assessment Plan Virginia Drought Assessment Plan

4. Drought Indicators 3 Main Indicators precipitation stream flow ground water levels Other Drought Status Report Standardized Precipitation Index Palmer Drought Severity Index Crop Moisture Index NOAA monthly and seasonal precipitation outlook

5. Drought Stage Levels Precipitation Precipitation deficits will be monitored by comparing current precipitation amounts with historical precipitation values as a percent of normal long-term average values. (as of April 18, 2008)

6. Regional Precipitation Deficit Map http://sequia.unl.edu/acis/program/acis_maps

7. Drought Stage Levels Surface Water (3 local gages)

8. Dry Marsh Run Opequon Creek Spout Run Blandy Park Rockwood Ridge

10. Drought Stage Levels Ground Water Above the 25 th percentile = NORMAL Between the 10th and 25th percentiles = WATCH Between the 5th and 10th percentile = WARNING Below the 5th percentile = EMERGENCY

14. Stage Declaration Watch Precipitation at or below normal for time period Stream Flow 10-25% Groundwater 10-25% Warning Precipitation at or below normal for time period Stream Flow below 10% Groundwater below 10% Emergency Precipitation at or below normal for time period Stream Flow at or below 5% Groundwater at or below 5%

15. Summary: What does the data tell us? Are we in a drought?

16. Drought Stage Declaration 2 indicators exceed stage level Watch - Encourage voluntary water conservation Warning - goal of reducing total water usage by 5-10% - water use restrictions consistent with local water supply conditions Emergency - mandatory water conservation requirements
