We report on the first epoch of observations of an ongoing circumstellar water maser monitoring project. The stars included in our program are S Perseus, U Herculis, VY Canis Majoris, VX Sagittarius, RX Bootis, IK Taurus and NML Cygnus. We present the spatial and frequency distributions of the masers. Continued observations are underway. We also present initial models of the spatial distribution of the masing regions and the physical environments in the circumstellar shell. We hope to derive the distance to these stars using the expanding cluster technique. Concurrent observations of the OH and SiO maser distributions are also presented. This work is part of Marvel's dissertation research which will be completed in June 1996.
