The Port of The Dalles and a group of supporters are working on a long-discussed plan for a dog park. The park is proposed for a spit of land between the cruise dock and the Marina along the Riverfront Trail. Port Executive Director Andrea Klaas says the piece of land is about five acres in size, and a group of supporters attended a recent Port meeting. Klaas says dog park supporters will come back to the Port board with a plan next month.
