Interstate Commission on the Potomac River Basin
The Interstate Commission on the Potomac River Basin Section for Cooperative Water Supply Operations on the Potomac seeks proposals for a facilitator for the 2018 Washington Metropolitan Area drought exercise. Applications are due June 29, 2018. Learn more…
For more than 20 years, ICPRB’s CO-OP Section has been conducting an annual drought exercise for the Washington metropolitan area.
During a drought, ICRPB coordinates water supply operations for the three major water utilities in Washington, D.C., and the adjacent suburbs in Maryland and Virginia. In preparation for such an event, ICPRB and the utilities practice communications and simulate operations of the system as they would occur during an actual drought.
Past Drought Exercises
- 2016: A special focus of the 2016 Drought Exercise was drought operations during a regional power outage. Participants explored their organizational and system backup capabilities and vulnerabilities.
- 2015: The scenario for the 2015 Drought Exercise was autumn low flow conditions, and one of the focuses of the exercise was potential operational considerations that might arise during WSSC’s planned rehabilitation of Brighton dam in coming years.
- 2014: The 2014 Drought Exercise focused on vulnerabilities of regional drought operations during a power outage.
- 2013: The 2013 Drought Exercise focused on understanding and improving flow prediction tools.
- 2012: The 2012 Drought Exercise simulated operational decisions and the declaration of water use restrictions during a severe drought. The scenario assumed that the year was 2022 and that operations were coordinated with Loudoun Water.
- 2011: The 2011 drought exercise aimed to familiarize CO-OP staff and member utilities with the Potomac OASIS model. The model makes probabilistic forecasts that could help inform future drought operations. The exercise used stream flows based on the 2002 low-flow period and projected 2015 demands and reservoir sedimentation rates.
