  By using defect measures, we prove the existence of partially regular weak
solutions to the stationary Navier-Stokes equations with external force $f \in
L_{\text{loc}}^q \cap L^{3/2}, q>3$ in general open subdomains of
$\mathbb{R}^6$. These weak solutions satisfy certain local energy estimates and
we estimate the size of their singular sets in terms of Hausdorff measures. We
also prove the defect measures vanish under a smallness condition, in contrast
to the nonstationary Navier-Stokes equations in $\mathbb{R}^4 \times
[0,\infty[$.
