(Portland, OR)  --  Portland city officials say Mount Tabor Reservoir 5 hasn't been flushed after all.  The city initially said it would drain the reservoir of its 38-million gallons of drinking water after an 18-year-old was caught on security video apparently relieving himself in it.  But the city now says it has, instead, moved most of that water to another reservoir at Mount Tabor Park as an experiment to see whether the reservoirs can be used as water features after they're no longer used for drinking water.  Reservoir 5 has since been refilled.
