Didymo in U.S. Northeast

While didymo is certainly a large threat to trout rivers in the U.S. west, its discovery in the Connecticut River in Vermont a couple of weeks ago is even more alarming, given the already perilous conditions of many rivers and streams in the northeast. “Lawton Weber discovered didymo while fly-fishing the Connecticut River with a friend off his waterfront property in Bloomfield, in the Northeast Kingdom, on June 21. ‘I put my raft in the water and within a hundred feet I took a look at the rocks and said, “It’s didymo. We’re screwed,”‘ he said.” Dennis Jensen in the Rutland Herald.
