The Halligan Water Supply Project and the Northern Integrated Supply Project (NISP), which includes the proposed Glade Reservoir, are two separate water supply projects. The Halligan Project is sponsored by the City of Fort Collins, while NISP is sponsored by Northern Water on behalf of 15 northern Colorado water providers. More information on NISP can be found here:
Acre-foot (AF): The volume of water required to cover 1 acre of land to a depth of 1 foot (around 326,000 gallons). Currently, an average single-family home served by Utilities uses almost a third of an acre-foot of water a year.
Cubic foot per second (cfs): A water flow measurement. Water flowing at one cfs will deliver about 450 gallons per minute or 646,000 gallons per day.
Environmental Impact Study (EIS): The EIS provides detailed analyses of the environmental impacts of the project, along with impacts of other alternatives to enlarging Halligan.
Firm Yield: The estimated maximum amount of water that can be supplied by a reservoir under specified conditions.
National Environmental Policy Act (NEPA): NEPA requires identification and evaluation of alternatives to meet the purpose and need of the project.
Potable Water: Water that is safe for human consumption.
Raw Water: Water that is not treated for consumption and is typically used for irrigation or other nonpotable uses.
U.S. Army Corps of Engineers (Corps): Performs Environmental Impact Study before issuing permit.
