The paddleboard racks at Wildwood sit empty most afternoons right now. Not because nobody wants to float the flat, gentle stretch of the Roaring Fork that runs through North Star Nature Preserve, just east of downtown along Highway 82 toward Independence Pass. It's because, for the first time since the county started managing the property, they legally can't.
Pitkin County Open Space and Trails issued a mandatory closure of all river access within North Star in late July, and it's still in effect. That single word, mandatory, is the part worth sitting with if you live nearby. This isn't the familiar late-summer advisory that regulars have learned to shrug off. It's a different kind of rule, and county officials themselves say they're figuring out how to run it as they go.
A First In The Preserve's History
North Star has always had a soft closure trigger. When flows on the Roaring Fork drop below 60 cubic feet per second, the county posts a voluntary closure, essentially a strong suggestion to skip the float or launch from South Gate instead of Wildwood. Locals have floated through plenty of those low-water Augusts.
This year is different. The county set a new, harder threshold this year, 20 cfs, and once the river dropped below that line and stayed there for more than a week, the voluntary suggestion became an enforceable closure. Rangers confirmed the water had been measuring below 20 cfs consistently, with readings as low as 13.3 cfs, and citations for violating the closure start at $100.
"This is the first year that we've ever instituted a mandatory closure," says Jami McMannes, communications and outreach specialist for Pitkin County Open Space and Trails. She's said the county is treating it as uncharted territory and adjusting the approach as conditions change.
The logic isn't about visitor safety so much as riverbed safety. At 13 or 20 cfs, a paddleboard doesn't glide through North Star's flat water so much as scrape across it, and every scrape stresses a riparian system that's already stretched thin. The preserve's 245 acres include a fen and wetland complex, plus an elk migration corridor, features that don't recover quickly from repeated contact.
What The Numbers Looked Like Before This Year
To understand how unusual this is, it helps to see what "low water" has meant at North Star in recent memory.
| Year | Water Story | Voluntary Closure Began | Mandatory Closure |
|---|---|---|---|
| 2021 | Dry, warm summer | Mid-July | No |
| 2025 | High snowpack, high flows | Mid-August | No |
| 2026 | Thin snowpack, warm summer | Skipped straight to mandatory | Yes, by late July |
In the driest recent year on record, 2021, the river still only triggered a voluntary closure, and it held off until mid-July. In the wettest recent year, high snowpack pushed that same voluntary trigger all the way to mid-August. This year didn't just arrive early. It arrived with a tool that never existed in those prior years and jumped straight past the voluntary stage.
That timing lines up with what's driving Colorado's broader water year. Regional forecasters have already flagged 2026's light winter snowpack and warm summer as the reason fall aspen colors on the high passes are expected to turn earlier than usual this year. The same snowpack that feeds the Roaring Fork through the summer was thin to begin with, which helps explain why the river ran short of water sooner than the county's older voluntary trigger was built to handle.
Meanwhile, the preserve has only gotten busier. River use climbed from roughly 7,988 users in the dry summer of 2021 to 9,235 last summer, when high flows made floating easy for longer, an increase the county has been managing with tighter parking enforcement along Highway 82 for years. More people wanting the float, at the exact moment the river can least support it, is the pressure that made a stronger rule feel inevitable.
What's Still Open While The River Is Closed
The closure covers river access from just above South Gate down to Stillwater Bridge, and it applies to the water, not the land. A fair amount of North Star is still yours to use this month.
- The designated beach area remains open for wading and hanging out, though traveling upstream or downstream from it on the water is not permitted
- The James H. Smith Nature Trail and the Wildlife Viewing Platform stay open for walking and birding, heron colony included
- The East of Aspen Trail bordering the preserve is unaffected, and it's the one spot in the immediate area where leashed dogs are actually welcome, since dogs are prohibited at North Star itself, on land and on water
- At least one of the five permitted commercial operators, Elk Mountain Expeditions, already rents paddleboards and inflatable kayaks for stretches of river beyond the preserve, a workaround worth knowing about while the closure holds
Touching the riverbed anywhere outside the designated beach now counts as trespassing under the closure, which is a stricter standard than the old voluntary guidance ever imposed.
This Isn't The Only New Rule At North Star This Year
Here's the part that matters most for anyone who plans to be around North Star in future summers. The 20 cfs drought threshold is a reactive call, made this year and, by the county's own admission, still being calibrated. But it isn't the only sign that mandatory closures have become a normal tool at the preserve rather than a last resort.
Only months earlier, Pitkin County finished a five-year update to the North Star Nature Preserve Management Plan, adopted March 25, 2026, which gave rangers explicit authority to impose closures to protect sensitive periods like elk calving season. That's a different trigger than low summer flows, but the same underlying shift. A preserve that used to rely on voluntary compliance and posted signage now has two separate, formal reasons rangers can shut the river down outright, one for drought and one for wildlife timing.
That's worth remembering the next time North Star runs skinny in July or August. Given the snowpack pattern behind this year's conditions, low flows returning in a future summer isn't far-fetched, and there's no reason to expect the county to hesitate before reaching for the mandatory closure again now that it's been used once.
For East Aspen, that's a small but real recalibration of how the neighborhood's most-used stretch of river actually works. Checking the flow status on Pitkin County's Floating North Star page before heading out is worth building into the same routine as checking snow conditions in winter. The preserve isn't going anywhere. The rules for using it just got sharper teeth, and they'll keep them.
If you're the kind of East Aspen resident who likes knowing the why behind the changes in your own backyard, that's the same instinct Soffia Wardy brings to conversations about the neighborhood itself, whether that's a river closure or a question about the market down the road.
