High Columbia River water levels are effectively shrinking Hood River waterfront recreation beaches and parks.  Spring runoff is causing high water levels throughout the Columbia/Snake River system, but local concerns are focused on water safety in the run up to Memorial Day weekend.  The Port of Hood River says several local kiting and windsurfing schools are offering guide services now to provide safety and support for the unique water conditions.  Kite launching is still permitted from the Event Site but only in designated areas.  River current is stronger than normal at all waterfront beaches, so life jackets and constant adult supervision is a must for children swimming at the Marina Beach, the Hood River Waterfront Park beach, and even Frog, or Slackwater, Beach in the Nichols Basin.  Boaters and anglers are also urged to use caution, as the high water and stronger currents are creating navigational condition changes with hidden and floating debris in the river, including large logs.
