One of the largest, best-attended events in Estes Park all year is the July 4 fireworks display.

Thousands of visitors line the banks of Lake Estes and fill the Cherokee Draw recreation area early in the day, bringing lawn chairs, blankets to sit on, picnics, and games as they prepare to spend the day, waiting for the 9:30 p.m. light display.

“By all accounts, the joint-planning effort to improve event safety and coordinated communication among Estes Valley Recreation and Park District, Emergency Management Services, law enforcement, and fire district staff and officials was a palpable success,” Tom Carosello, executive director of the Estes Valley Recreation and Park District reported to the district’s board of directors last week.

“This year’s initiative was led by Ian Stewart, Estes Park chief of police, and reports from each agency during and after the event indicate a vast improvement in crowd control and behavior, site logistics, traffic control, and incident-response rate,” according to Carosello’s report.

Apparently, some citizen issues arise during and after the Town’s pyrotechnical engineering contractor, Brighton’s Tri-State Fireworks, provides a 30-minute light show.

During the show, people watching from near the Fisherman’s Nook area at the east end of the 9-hole golf course and Lakefront Street have fireworks debris falling from the sky on them, which causes consternation among some.

Others are more concerned about the physical debris left behind, both by the light show and by people. One individual this year took to social media to spread his concerns. While the writer voiced general concerns about trash on the Lake Estes Trail, he did say, “It was heartbreaking to see fireworks fragments floating all along the water’s edge.”

“I do get a few comments (rather than questions) each year concerning the potential for contamination from the show’s ‘fallout,’ mainly concerning the amount of paper debris which settles on the shoreline and lake, but also a few comments about how the sound could affect wildlife,” Carosello said.

Concerns about how the fallout from fireworks affects ecosystems are becoming a more widespread topic among environmentalists nationwide.

According to a report from the Environmental Protection Agency, fine particulates dispersed by fireworks can contribute to decreased lung function, increased respiratory distress, aggravated asthma, and COPD.

A 2023 study released by “Pacific Conservation Biology” reported “that nearly 75% of companion animals studied – from horses to dogs to smaller mammals – showed fear responses to fireworks.”

Also reported by ecologically oriented publications, including “Shun Waste,” is the effect of fireworks on potential water pollution. In a June 2025 story for that publication, author  Brian Barton wrote, “The heavy metals and toxins released can be washed out of the air by rainfall, accumulating in and polluting local watersheds, rivers, lakes, and oceans.

A joint team from EVRPD, the police department, the town’s events department, and the Estes Valley Fire Protection District will monitor next year’s celebration.

“Next year is the 250 anniversary for the country, for the nation, so that could be interesting,” Carosello told his board of directors.
