  23. expectations and/or concerns for 2013 Areas where water supply concerns overlap with livestock water needs.

  24. ActionsDNR, in collaboration with IDALS, Igov, HSEMD, USGS and others continue to closely monitor conditions across the state. our hydrogeologists work with communities and water utilities to model potential supply or conflict areas and identify potential solutions to supply shortages.

  26. Planning considerations short term long-term tools and resources

  27. Short-Term • Monitor Your Conditions • Supply and Demand • Pay close attention to the Drought Monitor, local streamflow and precipitation, or other available data. • Write, review, and/or update a Drought Preparedness and Response Plan

  28. State-of-the-art drought assessment in the U.S. since 1999 Collaborative effort between NOAA, USDA and NDMC Composite indicator blends objective indicators and indices with field input from over 350 experts Policy implications in Farm Bill/USDA, IRS, NOAA-NWS and several state drought task forces “Go to source” for media and the public U.S. Drought Monitor (USDM): • droughtmonitor.unl.edu

  29. Early Warning? • Early warning: • Early warning involves forecasts based on climate projections and the area’s drought history, possible outcomes of developing drought events, and answering questions about how long a drought might last and how severe it might be. • Effective early warning systems should involve both technology and all interested parties in drought planning and response.
