  We study the stationary nonhomogeneous Navier--Stokes problem in a two
dimensional symmetric domain with a semi-infinite outlet (for instance, either
parabo-\\loidal or channel-like). Under the symmetry assumptions on the domain,
boundary value and external force we prove the existence of at least one weak
symmetric solution without any restriction on the size of the fluxes, i.e. the
fluxes of the boundary value ${\bf a}$ over the inner and the outer boundaries
may be arbitrarily large. Only the necessary compatibility condition (the total
flux is equal to zero) has to be satisfied. Moreover, the Dirichlet integral of
the solution can be finite or infinite depending on the geometry of the domain.
