An observational search for water masers in the galactic center region is described, and the resulting failure to find the theoretically expected number is discussed. The search found three new weak masers whose energy sources are probably B stars. Possible explanations are a different initial mass function at the center, suppressed maser emission, or stochastic bursts of star formation. The first, which holds that the lack of masers is due to a lack of massive stars, seems incompatible with the Lyman photon flux from the area. The second, which calls for disruption of masers by passing bulge stars, is valid only out to a few pc from the galactic nucleus and is therefore unsatisfactory. The third explanation is plausible. If star formation at the center is not governed by a large-scale mechanism, star formation there is then stochastic and may now be in a lull. All the water masers from the most recently formed stars would by now have died out.
