A 19 year old man was cited for urinating in Mt. Tabor's Reservoir 5. Security guards watched the incident as it was happening early Wednesday morning and were able to shut off the reservoir and call police.  The man was cited for public urination and trespassing.  The water bureau now has to drain and clean the 50-million gallon reservoir, a process that will take several days.  The water bureau director says public health was never at risk.
