Sloan's Lake's $50 Million Fix Isn't Coming From Where You'd Guess

On Wednesday, September 2, Mayor Mike Johnston stood near the jetty on Sloan's Lake's north shore and told a crowd that Denver was finally putting real money behind fixing the city's largest lake. Kurt Weaver, who has run the Sloan's Lake Park Foundation for years, made a joke about Roger the Elephant, the unfortunate star of the old Manhattan Beach amusement park that once stood on this same shoreline. Sometime during the amusement park's run between 1891 and 1914, a hot air balloon spooked Roger, children fell from his back, and one died. The lake became a public park in 1923 and has been drawing crowds ever since.

That history matters here because it sets up the real question this announcement raises for anyone who actually lives around the lake. Everyone covering the story led with the number: $50 million. Almost nobody explained where that money is actually coming from, and the answer says more about how this neighborhood works than the dredging plan itself does.

The Headline Version Everyone Already Has

The basic facts are easy to find. Sloan's Lake has been losing depth for decades. City officials now put the historical depth at 8 to 12 feet, down to an average of 2.5 to 3 feet today. An earlier Denver Parks and Recreation environmental assessment used a different baseline, 15 feet historically against a current average of 3.5 feet with a maximum of 8 feet in the deepest sections. The two figures don't match exactly, but they tell the same story: the lake has lost roughly half its depth, and the shallower water heats up faster and grows algae more easily than it used to.

That combination caught up with the lake in July 2024, when a string of near-100-degree days triggered a toxic algae bloom that killed an estimated 2,000 fish. The lake still draws about 2 million visitors a year for paddleboarding, dog walking, and the loop trail around its 2.6-mile perimeter, but swimming has been off limits for years because of the water quality.

That's the part every outlet covered. It's not the part that explains why this is happening now, in September 2026, instead of five years ago.

Where the Actual Money Comes From

The $50 million breaks down like this:

The $5 million wastewater contribution makes sense on its face, since Sloan's Lake functions as a stormwater basin for a watershed that stretches into Lakewood, Wheat Ridge, and Edgewater. The bond money is straightforward too. But four out of every five dollars in this plan come from a redevelopment district most residents have never heard of, and that district exists because of something that happened in the neighborhood thirteen years ago.

The old St. Anthony Central Hospital sat a few blocks from the lake until it relocated to Lakewood. In 2013, the city created the St. Anthony Urban Redevelopment Area to capture the growth in property values across the surrounding blocks as that site and the area around it redeveloped, and reinvest that growth locally. That's what a tax increment district does: it doesn't raise anyone's tax rate, but it channels the extra revenue generated as land gets more valuable back into the same footprint instead of into the city's general fund.

In practical terms, the money paying for four-fifths of this dredging project has been accumulating in the background as Sloan's Lake grew into the neighborhood it is today. Builder Aaron Foy, whose company BLVD Builders has been developing new homes a block from the park, priced a five bedroom house at 4444 W. 28th Avenue at $2.98 million this year, with a second home nearby at $2.4 million. He's told the Denver Gazette the area is starting to draw comparisons to Berkeley, Washington Park, and Bonnie Brae. That kind of appreciation is exactly what feeds a tax increment district. The neighborhood's own growth is what's paying to fix the water it grew up around.

The Ballot Measure Wasn't the Rescue Plan

This matters because it corrects a story a lot of residents have probably half believed. Last November, Denver voters approved a Vibrant Denver package worth roughly $950 million spread across 59 projects citywide, including money for Red Rocks Park and Amphitheatre upgrades. The Sloan's Lake Park Foundation had asked for $130 million to fix the lake. The bond gave it $5 million.

"Five million is obviously better than nothing, and we want to get started on this as quickly as possible because we are at risk of losing a great lake."

That's Weaver, talking to Rocky Mountain PBS last fall, before this month's announcement changed the math entirely. The bond vote wasn't the mechanism that ultimately unlocked serious money for the lake. It just happened to be the most visible one, because it's the one residents got to vote on.

What Actually Changes This Year

Here's the part that matters if you live near the lake and are wondering whether anything looks different by next summer. Almost nothing, yet.

The Denver Urban Renewal Authority board is expected to take up the proposal at its meeting on September 14. If it clears that vote, the plan still needs approval from the full Denver City Council. Assuming both happen, the city expects to finish contracting and federal permitting through 2027, with construction starting in 2028. The project itself is projected to take about 30 months once it begins, and officials have said they intend to keep the park largely open during construction, with only parts of the lake closing temporarily.

So the realistic timeline for a visibly deeper, cooler Sloan's Lake runs into 2030 at the earliest. Nothing about this fall's plans changes because of Wednesday's announcement.

The Neighborhood Isn't Waiting Either Way

What has changed, steadily, over the past couple of years, is everything around the lake that doesn't depend on its water quality. Odell's Sloan's Lake Brewhouse, on Perry Street, runs a small-batch pilot brewing system with a rooftop patio built specifically to face the water and the mountains behind it. Across Sheridan Boulevard, the Edgewater Public Market has grown into a genuine food hall anchored by Black Box Bakery and Saigon Noodle Club. A few blocks into West Highland, Paperboy opened its first location outside Texas this spring, joining a stretch that already includes Root Down and Linger. Inside the Lakehouse condo building, ChoLon and Gusto have been running since March 2024, with ChoLon's lake-facing patio turning into the draw of the room on cooler September evenings.

Every Friday from June through September, the Sloan's Lake Farm & Flea sets up on North Raleigh Street with local food vendors and live acoustic music. None of that activity is contingent on dredging. It's running on the neighborhood's own calendar, which moves a lot faster than a municipal permitting process.

Two Dates Worth Knowing

If you're weighing whether to get out to the lake before the weather turns, here's what's left on the 2026 calendar:

• The Colorado Dragon Boat Festival already wrapped its 26th year on August 29 and 30, drawing the crowds that make it one of the larger dragon boat events in the country.
• Jamming on the Jetty, the Sloan's Lake Park Foundation's own fundraiser, returns for its 11th year on Saturday, September 19, from 1 to 8 p.m. It's free, family friendly, and runs live music and food trucks along the jetty area near Byron Place and Utica Street. Every dollar raised through food and drink sales goes back to the foundation's work on the lake.

There's something almost funny about the contrast. The foundation has spent more than a decade running a beer-and-band fundraiser to chip away at a problem that ultimately got solved, in large part, by a tax district nobody at the festival was thinking about. Grassroots pressure clearly mattered. Weaver and the foundation spent years pushing the city to act, and that pressure is part of why this proposal exists at all. But the dollars that actually move the needle came from thirteen years of quiet property value growth in the blocks around a hospital that isn't there anymore.

That's worth sitting with the next time you're at Jamming on the Jetty, or walking the loop trail past Odell's rooftop, or reading whatever comes out of the DURA board's September 14 meeting. The lake's future and the neighborhood's growth have been running on the same clock longer than most people around it realized.
