Staff will provide an overview of the planned Water Efficiency Plan update
process, which is underway and will continue through 2024. Additionally,
Commissioners will engage in a feedback collection activity focused on
demand management strategies (conservation and efficiency programs,

FROM: Michael Neale, Water Resources Engineer
& Water Resources Division Staff
RE: March 2023 Water Resources Division Staff Report
Purpose
This memorandum is intended to update the Water Commission on water resource conditions for
the City of Fort Collins Water Utility (Water Utility) and provide updated outlook information. For
additional information, please refer to the City’s website: https://www.fcgov.com/utilities/water-
status
Supply and Demand
• Water Supply – During the month of March, water supply consisted of 58% from the Cache
La Poudre River, and 42% from Horsetooth Reservoir.
Cache la Poudre Basin Snowpack: Natural Resources Conservation Service SNOTEL:
https://www.nrcs.usda.gov/wps/portal/wcc/home/quicklinks/states/colorado/products/basingraphs
Cache la Poudre River flow: Graphical data for the Poudre River is available on-line at:
• Cache La Poudre River at the Canyon Mouth
https://dwr.state.co.us/Tools/Stations/CLAFTCCO?params=DISCHRG
Water Supply Considerations:
• Water Resources Division maintains close communication with Northern Water regarding
any drought response or policy action affecting the CBT system. As of now, there is no
indication of drought management action needed from Northern Water.
• Water Resources Division is closely monitoring the hydrology of the Colorado River basin,
the statewide and regional discussions around the Colorado River Compact, and any demand
management action by the Federal Bureau of Reclamation in response to drought in the
Colorado River basin.
• Currently, no drought management action is in effect. If drought management action is
deemed necessary, the Water Shortage Action Plan (WSAP) is in place to guide our
decisions and actions (fcgov.com/WSAP).

from Apr 06 - Oct 31, 2023
ASSUMPTIONS
• Three scenarios of projected demands and remaining
supplies through the end of the Water Year (Oct 31)
DEMANDS (treated only)
• Average Demand is projected demand (+ 5%)
• Low Demand is projected demand (-10%)
• High Demand applies historical worse case factor to monthly
projected demand
SUPPLIES
Poudre - Fire Impacted Scenarios
• Low supply is a severely fire impacted poudre - 60% of the
annual average intake. Average supply is a moderately
impacted poudre - 70% of average. High Supply - 90% of
average Poudre
Horsetooth Reservoir
• Horsetooth Supplies include CBT, NPIC MU & Windy Gap
• CBT supply is 60%, 70% and 80% quota,
• NPIC MU allocation is 2.25, 2.50 and 2.80 AF/share
• Windy Gap is 2,100 AF (Nov-May). 70% and 80% quota have
additional 1,750 AF Windy Gap pumped (Jun-Oct)
• All remaining Horsetooth raw water obligations have been
deducted
• 1,500 AF exchange of Joe Wright water for CBT is included
Horsetooth Carryover Objective
• Amount of this year's CBT supply to carryover into next year
• Max amount allowable is 4,190 AF before 10% shrink
