Schutro , Pat To: Schutrop, Pat Cc: tom.mathisen@crystalmn.gov Subject: RE: Community Water Suppliers Drought Response From: MN Department of Natural Resources m iito:dnr.0 ates.mndnr. ov Sent: Wednesday, May 15, 2013 2:04 PM To: Tracy, Bert Subject: Community Water Suppliers Drought Response www.mndnr.gov The Department of Natural Resources is contacting Minnesota's community public water suppliers in follow-up to last fall's communication about drought response actions. Dry, hot conditions in both 2011 and 2012 have posed challenges to many public and private water supplies. Much-needed winter precipitation has helped alleviate drought intensity across most of the state, but additional spring rain is needed to provide recharge to our aquatic systems. As of April 30th, the U. S. Drought Monitor displayed that in Minnesota: 91 % of the state is Abnormally Dry or worse 46% is experiencing Moderate Drought or worse 15% remains in Severe Drought In preparation for unknown weather patterns in 2013, the DNR encourages water suppliers to do the following three things: �. Review the state's Drought Plan Matrix (on the DNR website; a link to the site is embedded below) 2. Implement the drought response measures in your public water supply plan, if you have one, and the applicable steps in the Drought Plan Matrix for water suppliers 3. Promote water conservation to your customers and clients 1. Review Minnesota's Drought Plan Matrix Minnesota has a statewide Drought Plan that provides a framework for responding to droughts. It is an important resource for all public water suppliers. It outlines five drought phases, which correlate to the U.S. Drought Monitor. It identifies the actions public water suppliers must take as each drought phase is reached. At this point, 91 % of Minnesota is experiencing some level of drought, with notable portions of the state in the moderate and severe categories. All public water suppliers should be aware of their planned drought response, and the majority should begin implementing specified actions contained in the Drought Plan. 2. Implement Drought Contingency Measures and Prepare Communications to Users If you serve over 1,000 people, you should have a Water Supply Plan that includes sections related to your drought preparedness, drought response and water conservation programs. Now is the time to review those sections and implement the planned actions. If you do not have a Plan, you can still ask your customers/clients to reduce their use of water and you can implement at least basic conservation measures. 91 % of Minnesota is in at least the Drought Watch Phase. That means public water suppliers need to be providing conservation information to their customers and requesting them to implement voluntary measures to reduce water use. Please work on preparing these communications and sharing them with your customers throughout the coming months. Just over 15% of the state is at the Drought Warning Phase. In accordance with the Plan, suppliers implement the water use restrictions covered in their water supply plans, and implement water use reduction actions with a goal of reducing water use to 50% above January levels. 3. Promote Conservation Water conservation will reduce the demand placed upon groundwater and surface water resources, and on municipal water supply systems. DNR encourages you to actively communicate with your customers on the importance and benefits of water conservation. Spring is an excellent time of the year to affect the summertime practices of your customers and to guide them to the benefits of conservation. Given the severity of the fall drought in both 2011 and 2012, communities all recognize the value of protecting water supplies for the long-term. Additionally, communities may undertake water audits and leak detection, which often leads to significant reductions in water loss as well as cost savings. Drought highlights the challenges we face as water supplies are stressed and recent increased media and public attention has been focused on water resources, all across the state. The need for clean and robust supplies exists at all times, and underscores the need for planning for long -tern sustainable water supplies for all communities and homes. More Information and Contact Resources Visit the DNR website to find the latest information and fact sheets on the drought. Additionally, please direct specific questions to: Princesa VanBuren Hansen, Water Use Specialist, princesa.hansen(?_state.mn.us, 651-259-5731 Greg Spoden, State Climatologist, re o .s oder state.mn.us. 651-296-4214 The DNR seeks to maintain an open partnership with you in providing safe, reliable drinking water sources to the citizens of our state. When facing the challenges posed by a drought, we must work together to ensure the public understands the implications of their individual actions and how everyone can take steps to ensure we are prepared to adapt in case dry weather patterns persist. We appreciate your participation and engagement in achieving these goals. �lli�lt$ DEPAATMCIT OF NATURAL R SOURCES Minnesota Department of Natural Resources info. dnr staLq.mn.us STAY CONNECTED: SUBSCRIBER SERVICES: Manage Preferences I Unsubscribe I Heln I Sign-up for other Minnesota DNR notifications This email was sent to bUaCAwk*llwallsymq,ciov on behalf of: Minnesota Department of Natural Resources - 500 Lafayette Road Saint Paul, MN 55155 • 1-888-MINNDNR
