Massachusetts Trout Stocking Report 2026

Every sentence here comes from the Massachusetts Division of Fisheries and Wildlife (MassWildlife), and each section names its sources. Updated .

The Massachusetts Division of Fisheries and Wildlife (MassWildlife) stocks brook, brown, rainbow and tiger trout from five hatcheries, in spring and in fall. Its spring 2026 plan was over 400,000 trout for 450 lakes, ponds, rivers and streams in 264 towns, and its fall 2026 plan over 70,000 more. There is no schedule to look up in advance: MassWildlife does not post one, to keep things fair. Its trout stocking report shows each water as it is stocked instead, updated daily through both seasons.

The MassWildlife trout stocking report

A map and a table of what has been stocked this season, updated daily while stocking runs in spring and fall. The table can be filtered by town or by water. Zoom the map to your area and select an icon for its details, or type a water or town into the table's search to see every stocking reported there. Stream reaches are highlighted only to show the general area, so try other stretches of the stream too.

When Massachusetts stocks trout

Spring

Spring stocking starts in the Southeast District and spreads across the state as ice and weather allow; in 2026 it was set to begin in mid-March. The fish are getting bigger. Ten years ago less than 60% of stocked trout were over 12 inches; for spring 2026 the plan was 82%. It also included 2,500 tiger trout of 14 inches and up, raised only at the Sandwich hatchery, and 1,000 retired brood fish: 600 brown trout of 18 inches and up and 400 brook trout.

Fall

Fall stocking begins around the last full week of September, depending on water temperature, and ends in mid-October. The 2026 plan was over 70,000 trout: 10,750 brown trout over 12 inches, 16,300 rainbows of 12 to 13 inches and 43,500 rainbows over 14 inches.

Rules on stocked water

  • Trout may be kept all year: 6 a day from 1 January to 31 December, no more than 3 of them brook, brown or tiger trout in any combination.
  • There is no trout stamp. A freshwater fishing license covers trout, and anglers 15 and older need one.
  • Eight areas are catch and release only, with artificial lures, and no bait of any kind may be carried there.
  • Two big reservoirs keep seasons set by the Department of Conservation and Recreation (DCR), not by MassWildlife. Quabbin opens on the third Saturday in April; its boats come off in October, but the designated shorelines stay open to 31 December. Wachusett runs from the first Saturday in April to 31 December and Sudbury to 30 November, shore fishing only at both. MassWildlife's regulations page still gives older closing dates; DCR's are the ones that apply.

How to hear about a stocking

  • The stocking report is the place to watch: MassWildlife updates it daily during the spring and fall seasons, as waters are stocked.
  • The MassWildlife Monthly email newsletter announces when a season's stocking is about to start.
  • During April school vacation week MassWildlife holds public stocking events, where you can help stock trout and put questions to its biologists. Otherwise, say hello if you see the trucks.

Worth knowing before you go looking

  • Stocking can change with staffing, equipment, water levels and weather, and MassWildlife says so on the report itself.
  • Only waters with public access are stocked, so a private pond never is.
  • In most waters, stocked trout are a spring fishery. They go into lakes, ponds and rivers that turn too warm for trout in summer, and most do not survive beyond the spring.

From MassWildlife: Trout Stocking Report and MassWildlife: FAQs About the Fish Stocking Program.

Which day to fish it

The schedule says where the fish went in. Which day to go is a different question: the forecast scores each day of the week for trout at the water you pick, from its water temperature, the wind and the weather.
