ROXBURY, Vt. — The state of Vermont is still trying to get the Federal Emergency Management Agency to help pay for repairs to the fish hatchery in Roxbury, the state’s largest remaining repair project following flooding from 2011’s Tropical Storm Irene.

At issue is whether FEMA should help pay for a replacement hatchery that meets federal clean water standards.

When Irene hit the 1891 hatchery, it swept 90,000 fish downstream and filled its outdoor ponds with gravel and silt.

But the state can’t restore the hatchery to its pre-flood condition because it would be out of compliance with federal water quality laws.
