Colorado’s river surfers are feeling the impact of an unusually low-water year across the state. A warm, dry winter—widely linked to worsening climate change—has left rivers like the South Platte running far below typical summer levels, shrinking what many riders are calling the shortest surf season they can remember. For Denver-area residents, this isn’t only a recreation story; low flows often signal broader water-stress conditions that can affect everything from municipal systems to residential plumbing reliability.
Surfers like David Riordon, who has spent nearly a decade riding standing waves in Colorado, describe the surfing community as an early warning system for the state’s rivers. When the waves disappear, it’s a visible sign that water availability has shifted. And in the Denver metro area—where homes, businesses, and aging infrastructure depend on consistent pressure and predictable supply—water extremes (either too little or too much) can expose weak points in pipes, sewer lines, and household drainage systems.
Colorado’s “standing waves” went quiet—and it points to a bigger water story
Who is seeing it first
David Riordon (a longtime Colorado river surfer) and Jimmy Switzer (who has river bodyboarded for 13 years) say this season’s water levels feel abnormal. Andrew Martens, a Denver surfer in his fourth season, reported he couldn’t surf River Run Park at all this year due to low flows.
What happened on Colorado rivers
River surfing relies on “standing waves”—waves that stay in one place, often shaped by engineered river features that create a surfable hydraulic jump. But when flows drop under key thresholds, those waves flatten, become inconsistent, or turn unsafe.
Where the impacts were most noticeable
In the Denver area, River Run Park on the South Platte River near Sheridan (downstream of Chatfield Dam) is a core surf spot with three man-made waves. Low water also affected well-known surf and whitewater destinations in Buena Vista, Gunnison, Pueblo, Montrose, Glenwood Springs, and Salida.
When the surf season shrank
Typically, the surf window runs from May into mid/late summer, depending on dam releases and snowmelt. This year, riders say the season was dramatically shorter. Data cited in the report shows June flows at River Run Park stayed mostly below 50 cubic feet per second (cfs), while local surfers generally look for around 150 cfs for consistent, surfable conditions.
Why flows stayed low
The report attributes the situation to a historically warm, dry winter and worsening climate trends. It also notes the importance of water management decisions, including releases from Chatfield Dam and whether flow-support programs are activated elsewhere—like the Voluntary Flow Management Program (VFMP) that can help maintain summer flows near Salida in some years.
What low river flows can mean for Denver homes and plumbing systems
While the news focuses on surfing, low-flow conditions can be a “stress test” for the systems that move water into and out of Denver-area properties. In Denver and surrounding communities, shifts in water availability and changing usage patterns can contribute to practical plumbing headaches, including:
1) More concentrated buildup in drains and sewer lines: When less water is moving through lines, grease, soap scum, debris, and sediment may not flush as effectively—raising the chance of slow drains and backups.
2) Pressure and performance changes: Neighborhood water pressure can fluctuate based on demand and system operations. If you’re already dealing with partially blocked lines or aging fixtures, these changes can make symptoms more obvious.
3) Hidden weak points showing up: Older pipes, bellies in sewer lines, or partially collapsed sections may “behave” differently when flow patterns change—sometimes leading to recurring clogs or sudden backups.
4) Seasonal “whiplash” risk: Colorado can swing from drought-like conditions to intense storms. After long dry spells, sudden heavy rain can overwhelm drainage pathways, expose cracks in sewer laterals, or trigger basement and crawlspace water issues.
A plumber’s perspective: water scarcity can create drain and sewer problems that feel random
From a plumbing standpoint, the biggest risk isn’t just that rivers are low—it’s that homeowners often ignore early warning signs in their own systems until a real failure happens. A slow kitchen sink, a gurgling toilet, or a recurring tub backup can indicate developing restrictions in a drain or sewer line. When water conditions are tight and flow-through is reduced, those restrictions can worsen faster and become full blockages.
In Denver, where many homes have mature trees and older sewer connections, root intrusion is another common culprit. A low-flow season won’t “cause” root intrusion by itself, but it can make an already-compromised line clog more frequently because there’s less consistent volume moving waste through the pipe.
How this connects to plumbing services in Denver (and why timing matters)
If you’re in Denver or the surrounding metro and you’ve noticed slow drains, repeat clogs, sewer odors, or backups, this is the time to get ahead of it—especially while the region is paying attention to water conditions. Preventive service is often simpler and less disruptive than emergency cleanup.
Drain and sewer-focused plumbing support can help by:
– Clearing stubborn clogs and restoring proper flow through branch drains
– Diagnosing recurring backups (often a sign of a main line issue)
– Inspecting sewer lines to pinpoint roots, cracks, offsets, or bellies
– Helping reduce water waste caused by hidden leaks or failing fixtures
For Denver homeowners, the goal is resilience: keeping water moving where it should, keeping wastewater moving out, and preventing avoidable damage when the next weather swing hits.
Why this matters specifically in Denver, Colorado
Denver sits at the center of Colorado’s shifting water reality: fast-growing neighborhoods, heavy summer demand, and climate-driven variability. When river surfers around Denver can’t ride River Run Park because flows are too low, it’s another reminder that water conditions aren’t just an environmental headline—they’re a local systems issue. In Denver, proactive plumbing maintenance is one practical way residents can reduce risk, avoid waste, and prevent emergencies tied to stressed infrastructure and changing conditions.
Actionable takeaways for homeowners during low-water periods
- If multiple fixtures drain slowly at once (toilet + shower + sink), treat it like a main line warning sign and schedule a diagnostic quickly.
- Avoid “chemical drain cleaner stacking.” Repeated use can damage pipes and often doesn’t remove the real blockage (grease, roots, or a broken section).
- Watch for gurgling sounds, sewer smells, or water backing up in the lowest drain—these are early indicators of a developing sewer issue.
- Use water smarter, not just less: run enough water when using disposals or draining tubs to help move solids through the line.
- Consider a camera inspection if clogs keep returning—especially in older Denver homes or properties with large trees near sewer routes.
