Location

From Portland, drive east on I-84 for about 39 miles (39.3 miles from the Jct. of I-5 and I-84). Take exit 40 and check in at the security checkpoint area. Continue on to the visitors center. You can see the main spillway from here.

Habitat and Birds

June is the best time to view gulls from this location because the annual Shad run creates a bit of a feeding frenzy at this time. Keep an eye out for the occasional Peregrine falcon and bird the small island that holds the visitors center for migrant visitors that might be stopping over for a rest.
