Sloan’s Lake Faces Cleanup Push as Dragon Boat Festival Considers Relocation
Efforts to clean up Denver’s iconic Sloan’s Lake are being renewed as concerns mount over blue-green algae and sediment buildup — issues threatening both public health and the future of the Colorado Dragon Boat Festival. Kurt Weaver, executive director of the Sloan’s Lake Park Foundation, says the lake’s warm, shallow conditions make it an ideal breeding ground for harmful algal blooms and recurring fish kills.
With the popular Dragon Boat Festival set to return, organizers warn that if the water quality doesn’t improve soon, the event could be relocated. “We’ve got to get it back down to a healthy depth,” Weaver said, pointing to sediment removal and water circulation as the only long-term fixes. While short-term measures are underway to clear a safe paddling channel, community members like Francisco Ledesma wonder why broader action wasn’t taken sooner.
Weaver emphasized that recent funding — including $5 million from Denver’s Vibrant Bond — will jumpstart interim projects and planning for larger-scale restoration. He’s urging residents to pitch in by keeping the park clean and removing any debris. “We want our dogs to swim in there. We want to swim in there. We want to be able to actually use the lake again,” he said.
The community’s growing sense of urgency may finally help bring Denver’s largest lake back to health — before one of the city’s most cherished cultural events is forced to paddle elsewhere.
