Water Shortage Action Plan


The Water Shortage Action Plan (WSAP), previously known as the Water Supply Shortage Response Plan, establishes conditions and restrictions to manage Utilities' water supply in the event of projected water shortages as established by City Code Section 26-167(a).

Following a two-year review and engagement process, the plan was approved by City Council April 21, 2020, and is effective as of May 1, 2020.

WSAP Summary

Water Restrictions

The WSAP includes a comprehensive list of tactics and restrictions to be implemented in the event of a water shortage, as declared by the City Manager.

An effective response to water shortage requires a suite of strategies and tactics – no single water restriction will provide the response needed for most water shortages. The following guiding principles, not listed in order of priority or importance, will be followed as possible during a shortage.

  • Restrict less-essential uses first and avoid restrictions on more essential uses.
  • Minimize adverse economic impacts.
  • Protect public and community activities.
  • Implement extensive public information and media relations program.
  • Avoid irretrievable loss of natural vegetation.
  • Explore alternative water supply options.
    Collaborate regionally and with other water service providers.

For a full list of water shortage tactics and strategies, including restrictions, see Chapter 1 of the WSAP.

Voluntary indoor water use strategies encourage optional and additional water use reductions based on water-efficient best practices and will be promoted concurrently during any mandatory outdoor water use restrictions. 

Mandatory outdoor water use restrictions are required water use reduction strategies that are subject to monitoring and enforcement. 

Alternative demand reduction actions may include a unique combination of mandatory restrictions and/or voluntary water restrictions. This level should be enacted when other levels are not adequate or appropriate to address a unique or extreme water shortage scenario.

Action Summary Table
Action Level Water Shortage Watch - Voluntary I - Low II - Medium III - High IV - Alternative
% Projected Water Shortage Potential Shortage 1-15% 16-25% 26-35% Unique and extreme water shortages not adequately or appropriately addressed by Water Shortage Watch or Levels I-III



Permits are available to allow for exceptions to assigned watering days and frequencies only, as described in Chapter 2 of the WSAP.

Permits may be issued for individuals or businesses unable to comply with watering restrictions for the following conditions:

  • New seed and sod
  • Medical/physical hardship
  • Religious objection
  • Large (four acres or greater) and City parks inactive areas
  • City and Community active areas
  • Raw or well water use

How To Apply for Permits


Chapter 3 of the WSAP focuses on enforcement of water restrictions. The enforcement, including fines, and permitting functions for Utilities’ water restrictions are designed to ensure compliance with the WSAP, as well as City Code Section 26-166 (Prohibition of waste). Enforcement of restrictions, together with ongoing public education and outreach, are needed to achieve the goal of decreasing water demand, thus minimizing the need for greater water restriction action levels. 

Future Updates

Per Chapter 4 of the WSAP, regular and frequent review of the WSAP and water shortage action measures is critical to ensure Utilities’ staff and customers are prepared for a water shortage. The WSAP should be reviewed at least every five years, or sooner as new information becomes available. Updates may be necessary during or following a water shortage event, updates to either the Water Supply and Demand Management Policy or the Water Efficiency Plan, or changes to City Code. The next update should be considered in 2023-2024 for potential adoption in 2025.


What is a Water Shortage?
Low water level on Horsetooth Reservoir

A water shortage occurs when the projected water supply is less than the anticipated water demand with a set amount of water reserves in storage. Water supply is planned to include a storage reserve factor that equates to 20% of annual demand in storage through a 1-in-50 year- drought (a drought that has a 2% chance of occurring each year). The following events, or combination of, are examples that could trigger a water shortage:

  • Drought (greater than a 1-in-50 year)
  • Contamination or other water quality issues
  • Treatment plant offline or another infrastructure issue

Fort Collins Utilities uses water supply projections, meteorological forecasts and available storage to estimate whether supplies are adequate to meet demand. If supplies are less than planned, water restrictions may be necessary in order to manage the availability of water for use in the immediate future or within the planning horizon for managing the water supply, as outlined in the current Water Shortage Action Plan. The plan applies only to customers in the Fort Collins Utilities service area.

Past Water Shortages
Neighborhood with dry lawns
  • 2013 – Briefly responded with level 1 restrictions: Caused by drought and water quality concerns following the High Park and Hewlett fires. The fires carried soil and ash into the Poudre River, causing water contamination and the Colorado-Big Thompson quota for Horsetooth Reservoir was lower than usual.
  • 2002 – Responded with level 1, then escalated to level 2 restrictions. Caused by drought.
