A search for stellar water masers at Haystack Observatory has revealed the presence of a new component in the W3(OH) region. Observation of the 6(sub)16-5(sub)23 rotational transition for H(sub)2O at 22235.08 MHZ evinced the new feature at radial velocity v= -32 km s(sup)-1. The flux was substantially weaker than other components on W3(OH) and may be time-dependent. Implications of stellar maser evolution are briefly discussed.
