Game fish
The only major body of water in the town is the Joe's Pond, which covers and is partially in Danville and partially in neighboring Cabot to the west. The pond, an impoundment of the brook in West Danville, is the largest of the six bodies of water in the Joe's Brook watershed, which is in turn part of the Passumpsic River watershed. Game fish in the pond include lake trout, smallmouth bass, northern pike (which were illegally introduced), rainbow smelt, rock bass, pumpkinseed, chain pickerel, yellow perch, and brown bullhead. Plant species in the pond include the common mare's tail ("Hippuris vulgaris") and the small bur-reed ("Sparganium natans").
