  Let $(\Omega,g)$ be a compact, analytic Riemannian manifold with analytic
boundary $\partial \Omega = M.$ We give $L^2$-lower bounds for Steklov
eigenfunctions and their restrictions to interior hypersurfaces $H \subset
\Omega^{\circ}$ in a geometrically defined neighborhood of $M$. Our results are
optimal in the entire geometric neighborhood and complement the results on
eigenfunction upper bounds in the author's previous work.
