No, you won’t get to go in a submarine during the Subs on the Slough event planned at 11:30 a.m. Friday, Aug. 16, by the Portland Water Bureau and Columbia Slough Watershed Council.

But you could get a free lunch, if you sign up in time.

Subs on the Slough will offer participants a free lunchtime tour, to enlighten folks about the water bureau’s underground drinking water source in the Columbia Slough watershed. Visitors also can see the solar array that offsets the bureau’s energy needs.

Lunch is provided at picnic tables along the Columbia Slough trail, at the Portland Water Bureau launch at 16650 N.E. Airport Way, in Portland.
