Fort Collins town leaders are concerned that a proposed reservoir project would negatively impact the Poudre River that runs through town. The city council voted unanimously Tuesday night to oppose the Northern Integrated Supply Project, which would build a dam off the Poudre River and create two reservoirs. One would be north of Fort Collins and the other by Greeley. Fort Collins wouldn't receive water from the project but council members are worried about the river. They say the scientific analysis in a federal environmental impact report was lacking. Council members say they'd rethink their opposition if their concerns are addressed. The project is proposed by Northern Water on behalf of 15 cities and water districts.
