  • Nice visit to see the dam and surrounding wetlands for the birds. Nice wildlife habitat for birds passing through this fly way.  more »
  • Our guide Travis took us on a fabulous (free) educational adventure up on top of the dam. If you haven't seen a boat pass through a functioning lock and dam system, this is your chance!  more »
