Finding Fish with Pond Maps

MassWildlife has provided maps of popular waterbodies to anglers and boaters since the 1950s. These maps contain information regarding stocking, public access, resident fish species, and a bathymetric (depth) map. Bathymetric maps are extremely useful to anglers, as different fish species often associate with specific underwater features. For example, bass prefer steep drop-offs and submerged plateaus, while trout occupy deeper, colder water.

Recently, MassWildlife began updating these bathymetric maps using new technology that renders underwater terrain with 100x the precision as the original maps. These new, more detailed maps allow anglers to focus their efforts within the habitats they choose with unparalleled accuracy. Anglers who ice fish or fish from shore will find these maps particularly valuable.

Anglers can find pond maps at mass.gov/dfw/pond-maps.

Our Coldwater Streams

MassWildlife defines a Coldwater Fish Resource (CFR) as a waterbody that contains at least one coldwater fish species (i.e., Slimy Sculpin, Longnose Sucker, Lake Chub, American Brook Lamprey, Burbot, Rainbow Smelt, Landlocked Atlantic Salmon, and Lake, Brook, Brown, and Rainbow Trout) that reproduced in that waterbody, or a connected tributary, and use such waters to meet one or more of their life history requirements. Protection of coldwater habitats is therefore critical for maintaining the overall health of coldwater fish species, which are ecologically, and in many cases, recreationally important fishes throughout Massachusetts. Once designated as a CFR, waterbodies are then afforded a greater degree of protection from potential human-caused alterations to their health. A map and list of currently designated CFRs can be found at mass.gov/dfw/cfr.
