text: The aqueduct formerly could also be fed directly by the Stearns and Brackett reservoirs (Framingham #1 and #2) and Farm Pond as well as indirectly by Whitehall Pond, Ashland Reservoir, and Hopkinton Reservoir which discharge into the Bracket Reservoir; for water quality reasons generally only the Foss Reservoir was regularly used for most of the aqueduct's history and is the only one of the reservoirs that is still maintained as an emergency water source.
