We compute the optical depth and duration distribution of microlensing events toward Baade's window in a model composed of a Galactic disk and a bar. The bar model is a self-consistent dynamical model built out of individual orbits that has been populated to be consistent with the COBE maps of the Galaxy and kinematic observations of the Galactic bulge. We find that most of the lenses are in the bulge with a line-of-sight distance 6.25 kpc (adopting R0 = 8 kpc). The microlensing optical depth of a 2 × 1010 M⊙ bar plus a truncated disk is (2.2 ± 0.45) × 10-6, consistent with the large optical depth (3.2 ± 1.2) × 10-6 found by Udalski et al. (1994). This model optical depth is enhanced over the predictions of axisymmetric models by Kiraga &am...
