December 17, 2025

Federal officials have released a “sobering” forecast of 2026 water levels in the Colorado River, with expected flows plummeting from previous predictions. Precipitation later in the winter could turn those dire forecasts around, officials say, but the current outlook is grim for a river already flirting with crisis.  Officials published the new forecast on Monday, only a day before negotiators and stakeholders from the river’s basin states gathered in Las Vegas for a three-day conference. The federal government has given states until February to agree on a longer-term strategy for managing low river flows. The Colorado River’s flow in 2026 (specifically, the unregulated inflow to Lake Powell) could be 27% lower than normal, according to the most probable scenario in the December forecast, with worst-case scenarios predicting even lower flows. The projection has worsened estimates released in November (16% lower than normal in most probable scenarios).

“We all know Mother Nature is a trickster and can often confound our expectations. We certainly hope she intends to do that this year,” said Wayne Pullan, the Bureau of Reclamation’s regional director for the Upper Colorado River Basin, on Tuesday. “But December’s outlook is troubling.”

The bureau, which manages federal dams, will delay water releases at Lake Powell to conserve supplies in the reservoir during the dry winter months in 2026, Pullan said. Even with those efforts, however, the lake’s water levels could fall to critical levels in 2027 as another disappointing year hits the basin. A bad water year in 2026 would compound already poor conditions from 2025, when river flows have been less than half of normal. The new forecast increases the possibility that water levels in Lake Powell could drop below the intakes for hydropower turbines and that releases from the lake could fall below the annual average required to meet the requirements of the 1922 Colorado River Compact, which governs water allocation between the seven states that use the river. Without above-average flows in future years to bring averages back up, or an interstate deal on how to manage drought, those low releases could set the stage for a legal battle on the river.

Here the water level is above dead pool, meaning water can be released via the river outlets, but it is below minimum power pool, so water cannot yet enter the penstocks to generate electricity.

#Colorado Senate Bill Helps With Water #Conservation — Northern Water ENews

December 17, 2025

Colorado Senate Bill 24-005 (SB5) seeks to reduce unnecessary outdoor water use by limiting high-water landscaping in commercial areas to conserve water amid mounting drought concerns. Beginning Jan. 1, 2026, the legislation will restrict non-functional turf (irrigated grass areas used for decoration), artificial turf and invasive plant species in non-residential settings.  

Implementing SB5 

SB5 requires changes to land-use code to specify these restrictions for the following applications:  

  • Commercial, institutional and industrial properties
  • Homeowner association common-interest community areas
  • Public spaces such as street right-of-way, medians, parking lots and transportation corridors
Restrictions and Applications  

Due to the value and appropriateness of higher water use and activity they support, SB5 does not apply to areas considered functional or recreational, including turf for athletic fields, parks and golf courses. 

The bill does not impact existing development; it applies only to new developments and certain redevelopment projects that require building or landscaping permits and disturb at least 50 percent of a site’s landscape. It excludes single-family residential properties, focusing instead on public and commercial areas where landscaping serves primarily for aesthetic purposes.  

New Landscape Rules Matter for Colorado’s Future 

Landscapes play a vital role to communities, but historical turf-heavy designs consume significant resources to meet social expectations. Today, more sustainable solutions exist that use less water while still delivering functionality. Allocating water budgets to landscape formats that provide the highest social value for the water invested is a sensible application to managing this scarce resource.  

Areas that are primarily ornamental can be designed to use less water than traditional turf grass while still providing important non-recreational functionality. For spaces that require turf-like groundcover, multiple alternatives exist that use less water than cool season Kentucky Bluegrass, including Tahoma31 warm season grass, Dog Tuff grass and a variety of native grass combinations that thrive in this climate with minimal supplemental needs. These alternatives support stormwater management, provide cooling and pollution mitigation, while also delivering enhanced benefits of habitat for Colorado’s native flora and fauna. Non-turf areas such as gardens and groves have plentiful options for perennials, groundcovers, shrubs and trees that use less water than turf while providing essential livability features to our region.  

Northern Water’s Role 

To support SB5 implementation, Northern Water has been providing training to regional municipalities, including the Growing Water Smart program from the Sonoran Institute. These workshops introduce new sustainable landscape options that meet municipal needs while also providing flexibility for cities to determine a unique sense of place for their regions. Northern Water and its partners also provide tools such as landscape designs and demonstrations at our Berthoud Conservation Campus so city planners and consultants can experience ColoradoScapes and understand their resource uses as they update land use codes. Many cities are excited to modernize the message their landscapes convey and have begun showcasing these features on their own properties.  

Lower Water, Higher Value Landscapes 

SB5 ensures that water resources are dedicated to areas with the highest essential and recreational use, while maintaining high quality, aesthetically pleasing commercial, industrial and transportation areas that require less water. These changes will create communities that show our region’s natural beauty and restore ecosystem services to our pollinators, birds and other animals, while offering an authentic Colorado experience.
