Mobagat is an alternative name for the Grote Veenderplas, a former sand-extraction lake situated near Lunteren in the municipality of Ede, alongside the A30 motorway.

The lake formed in the early 1970s when sand was excavated for construction of the A30, leaving a deep, bathtub-shaped basin with steep sides reaching up to 17 metres at its deepest point. The water is fed by seepage from the Veluwe. Covering roughly 9.

5–13 hectares, the lake is ringed by a green belt of trees and shrubs that gives it a sheltered, tranquil character.

The varied depth supports a rich mix of fish species, including carp, tench, bream, pike, and perch, and the water is managed as a fishing venue by Hengelsportvereniging Barneveld.

The site has been owned by SBNL Natuurfonds since the late 1980s, acquired partly by donation and partly by purchase.
