  The charged current cross section for neutrinos with energy of a few GeV is
reanalysed. In this energy range the cross section for the lowest multiplicity
exclusive channels is an important fraction of $\sigma_{CC}$ and the
approximation of describing the cross section with deep inelastic scattering
formulae may be inaccurate. Possible consequences of our reanalysis of the
cross section in the interpretation of the data obtained by deep underground
detectors on $\nu$--induced upward going muons (both stopping and passing) are
discussed.
