Some wanted to improve their views, others were seeking more acreage for farmlands. But the unintended consequence was a blow to the trout fishery. Battenkill lured anglers from around the world to its legendary banks promising a trout-fishing paradise, but some 30 years ago the river stopped giving up large numbers of fish, leading scientists, anglers, and concerned citizens to ask: What was killing the Batten- kill? “Trout like a river bottom with big rocks because the insects that they like to eat will live in all the nooks and crannies,” Cooperman said. When you have an eroding bank, it’s dumping dirt into the river, and all those nooks and crannies fill up and the river bottom looks like a paved road. You lose the insect population, the fish have no food, and so the river will support less fish.” “Back in the 1940s and ’50s the Battenkill was widely regard- ed as one of the best wild trout fisheries in the eastern United States,” said Michael Cooperman of the Moore Center for Science Conservation International who has studied the fishery. “Everyone from movie stars to the hoi polloi would come to Manchester to fish. But at some point between the mid-1980s and early ’90s the number of fish started to fall and the size started to decline and that caused a lot of concern.” In response, the Vermont Fish & Wildlife Department restricted the Battenkill to catch-and-release, meaning anglers had to return the fish they caught back to the river. At the same time, state, federal, and local biologists began to study the problem with an eye toward bringing the river back to its glo- ry days. There were lots of theories about what was keeping the trout numbers down: Disease? Water quality? Water temperature? But eventually, in the early 2000s a consensus emerged: it was a habitat issue. 78 74 VERMONT VERMONT magazine Magazine FALL 2019 “There were deep-pool habitats that would hold a few big fish and ripple habitats that would hold some of the small fingerling-size fish, but no real habitat for the in-between stages,” said Carl Schwartz, a biologist with U.S. Fish & Wildlife Service. “There was a lack of cover for the midsize fish. The little ones could hang in the riffle, but if the medium-size ones went in the deep pools they’d just become part of the big fish.” Meanwhile the Battenkill was be- coming more and more popular with recreational users such as ca- noers, tubers, and kayakers. To clear a path for them, a lot of commer- cial renters removed fallen trees, branches, and stumps that were in the river providing cozy little fish condos for the trout. That eventual- ly led to the main problem: a lack of cover and shelter for the fish. “Trout need places to hide from predators, other fish, ducks, otters, and eagles,” said Cynthia Browning, executive director of the Batten Kill Watershed Alliance, created in 2001 to promote good stewardship of the river. “And they need deep pools and shade to get away from the heat There were numerous reasons the Battenkill’s trout in the summer. Trees overhanging habitat declined, but the main causes were excess the banks provide shade, and the erosion and conflicts between river users. Erosion was big rocks, trees, and stumps that fell
