Twin Falls Open House May 5 to Highlight Rock Creek Water Quality Restoration Plan
The City of Twin Falls, Idaho, will host a public open house on Monday, May 5, from 5 to 7 p.m. at the Herrett Center to present details from a newly completed master plan aimed at restoring water quality in Rock Creek, one of the area’s most historically neglected waterways.
The Rock Creek Watershed Presentation and Open House will give residents a focused look at the top 10 prioritized projects identified in the plan, offering a more accessible entry point into a comprehensive document that runs 177 pages. The master plan was completed and approved in March, with projects ranked by a combination of feasibility and anticipated impact — the highest-priority items are those considered easiest to implement while delivering the greatest benefit to water quality.
Making a Complex Plan Accessible to the Public
Mandy Thompson, who works for the City of Twin Falls, said the open house is specifically designed to make the planning process understandable for everyday residents who may not have the time or inclination to work through the full document on their own.
“So it’ll really give the public opportunity to see what we’re doing without having to comb through that very large document,” Thompson said, according to reporting by Idaho News 6.
The event will also include information on how residents can stay informed as restoration efforts move forward. City officials have emphasized transparency and community involvement as central goals of the overall watershed initiative.
Rock Creek’s water quality problems are deeply rooted in the city’s history. Thompson noted that during the early part of the last century, the creek was used as a landfill, with various materials dumped into it over the years. The city’s first sewer system also discharged directly into Rock Creek. Thompson described the waterway as having spent decades in a kind of “out-of-sight, out-of-mind” state, with little public attention paid to the ongoing contamination.
Federal Funding and Community Voices Behind the Effort
The multiyear scientific groundwork underlying the master plan was funded through a congressional earmark secured by U.S. Representative Mike Simpson, which paid for three years of studies into the creek’s water quality challenges. The investment reflects the kind of targeted federal-local cooperation that has allowed Twin Falls to move from identifying a problem to developing a concrete, prioritized action plan.
Local fishing and conservation groups have also played a role in building momentum for the cleanup effort. Chris Foster, a member of the Magic Valley Flyfishers club, told Idaho News 6 that he has been part of discussions about improving Rock Creek for years — conversations that have grown over time to include more stakeholders, particularly those located upstream.
“The group was actually talking to more and more stakeholders, especially upstream,” Foster said, as reported by Idaho News 6.
Foster expressed optimism about what a cleaner Rock Creek could mean for Twin Falls as a whole — not just for anglers, but for the broader community.
“It would be just great. Not only would it be great for the city. We have people fishing here all the time,” Foster said. “However, when we know it’s cleaned up and we do have a lot [to do], it’ll be so much more for everybody.”
Rock Creek runs through Twin Falls and has long been a feature of the city’s landscape, though its water quality has limited recreational use and raised environmental concerns for generations. Restoring the creek is seen by city officials and local advocates alike as a meaningful quality-of-life improvement for current and future residents.
Residents who wish to review the full master plan ahead of the open house can access it through the City of Twin Falls website.
