The NOνA collaboration has constructed a 14,000 ton, fine-grained, low-Z, total absorption tracking calorimeter at an off-axis angle to an upgraded NuMI neutrino beam. This detector, with its excellent granularity and energy resolution and relatively low-energy neutrino thresholds, was designed to observe electron neutrino appearance in a muon neutrino beam, but it also has unique capabilities suitable for more exotic efforts. In fact, with an efficient upward-going muon trigger and sufficient background suppression offline, NOνA will be capable of a competitive indirect dark matter search for low-mass WIMPs. Interesting atmospheric neutrino measurements should also be possible. The cosmic ray muon rate at the NOνA far detector is about 150 kHz and provides the primary challenge for triggering and optimizing such a search analysis.
