Analytical expressions for width and conductance peak distributions for quantum dots with multichannel leads in the Coulomb blockade regime are presented for both limits of conserved and broken time-reversal symmetry. The results are valid for any number of nonequivalent and correlated channels, and the distributions are expressed in terms of the channel correlation matrix {ital M} in each lead. The matrix {ital M} is also given in closed form. A chaotic billiard is used as a model to test numerically the theoretical predictions. {copyright} {ital 1995} {ital The} {ital American} {ital Physical} {ital Society}.
