The Daleville Town Board unanimously voted not to join the Mounds Lake Commission at it's meeting Monday night.
The City of Anderson and the Town of Chesterfield have voted to be part of the commission, which would be tasked with overseeing a Phase Three study to determine if the project moves forward.
The Delaware County Council voted against joining, and Yorktown officials haven’t yet scheduled a vote.
Tim Maloney, senior policy analyst with the Hoosier Environment Council a group that has been very outspoken against the project, says he’s not sure it can move forward without a consensus.
"It’s not clear under the law, if it could proceed without everyone being part of it but it seems unlikely because the commission could impose its jurisdiction over communities that don’t want to be a part of it," said Maloney
Supporters say the reservoir, that would cost upwards of $400 million would drive development and provide a much needed water source for central Indiana.
Opponents express environmental concerns and lack of clear economic evidence.
