How it works
Use the map to zoom and pan to different regions of the state and discover new destinations for fishing. Zoom to the area you want to explore and then click on an icon for more information on that location. Stream reaches are highlighted to show the general area where stocking occurs—but fish swim, so be sure to investigate other reaches of the stream as well while respecting private property.
If you are looking for stocking information for a particular waterbody or town, use the table. Type the name of the waterbody or town into the search window to find all stocking reports for that location.

Note: Stocking is subject to change depending on staffing, equipment, and weather conditions.
2025 Trout stocking
MassWildlife stockes brook, brown, rainbow, and tiger trout in the spring and fall. This year’s fish are bigger and better than ever. While the quantity of stocked trout (measured in total pounds) has remained about the same for the last decade, MassWildlife has been steadily producing larger trout by adjusting hatchery growing techniques. Just ten years ago, less than 60% of stocked trout were over 12 inches—now, over 80% measure over a foot!
