Saturday at 2 p.m., South Portland stormwater program coordinator Fred Dillon and members of the land trust will lead an informational walk along Trout Brook at the Trout Brook Nature Preserve, starting at the trailhead on Providence Avenue. Attendees will hear  about recent restoration work at the preserve.
