HARRISBURG, Pa., Nov. 10, 2016 /PRNewswire-USNewswire/ -- The public is invited to again vote online for the 2017 Pennsylvania River of the Year, choosing from among four waterways nominated across the state, Department of Conservation and Natural Resources Secretary Cindy Adams Dunn announced today. Waterways nominated for 2017 are the Allegheny River (Middle & Upper) and Brandywine, Loyalhanna and Perkiomen creeks. "There is a spirit of good-natured competition surrounding this selection process that rallies community support around our deserving waterways and puts them in the public limelight," said Dunn. "These nominated rivers and streams showcase so many unique natural resources, recreational opportunities and incentives boosting local economies. They also show just how blessed this state is with its wealth of major rivers and streams, and committed folks willing to support them." Nominations were based on each waterway's conservation needs and successes, as well as celebration plans should the nominee be voted 2017 River of the Year. In cooperation with DCNR, selection of public voting choices is overseen by the Pennsylvania Organization for Watersheds and Rivers (POWR), an affiliate of the Pennsylvania Environmental Council. "The online public selection process continues to be increasingly popular as it enters its seventh year," Dunn said. The public can vote for their favorite state waterway beginning Monday, Nov. 14, through 5 p.m. Monday, Dec. 19. The website www.pariveroftheyear.org enables voting and offers details on nominated waterways and the River of the Year program. Voting will be managed through Woobox, an online contest application that restricts voting to one vote per email address. POWR, an affiliate of the Pennsylvania Environmental Council, administers the River of the Year program with funding from DCNR. Presented annually since 1983, this year's 2016 designation was awarded to the Susquehanna River North Branch.
