In 2004, the Vermont Legislature passed a bill banning the sale (January 2006) of lead sinkers weighing 1/2 ounce or less, and then the use (January 2007) of those lead sinkers in the state.
In June 2000, the Massachusetts Fisheries & Wildlife Board voted to prohibit the use of all lead sinkers for the taking of fish in Quabbin and Wachusett Reservoirs, the two bodies of water that support the core of that state's loon population.
The U.S. Fish and Wildlife Service has banned lead sinkers in two national wildlife refuges and Yellowstone National Park; restrictions have been discussed on the use of lead sinkers and jigs at other national wildlife refuges where loons and trumpeter swans breed.
