About the Neponset River
The Neponset River drains the country southwest of Boston and reaches tidewater at Milton Village before running through the Neponset marshes into Dorchester Bay. The gauge at Milton Village reads discharge and stage at the head of tide, which is the boundary that defines this fishery. Below the gauge the river is estuary; above it, freshwater.
The Neponset spent most of the twentieth century as one of the more abused rivers in Massachusetts, carrying mill waste and blocked by dams near its mouth. The recovery has been substantial. Water quality has improved markedly, the lower marshes have been protected as a state reservation, and fish passage work at the head of tide has reopened the migratory corridor for river herring for the first time in generations.
That herring run is what drives the fishing. Striped bass follow alewives and blueback herring into the tidal reach from April onward and stack up below the head of tide where the bait concentrates. Most are schoolies, but the numbers can be excellent and the fish are reachable from shore, which is rare this close to a major city. White perch hold through the brackish water much of the year, American eel are abundant, largemouth bass live in the freshwater river above, and bluefish occasionally push up from the bay in summer.
Access is genuinely urban and genuinely good. The Neponset River Greenway runs along much of the lower river with paths, bridges and bank access, and there is kayak access to the marsh channels and Dorchester Bay below.
One caution particular to this river: sediment contamination from its industrial past remains a live issue in the lower reaches, and state advisories on consuming fish taken here should be read before keeping anything. Catch and release is the sensible default. The fishing itself is excellent and improving, and the herring counts each spring are the clearest measure of it.
