Sloan's Lake Restoration in Denver: Behind the $50M Funding

Three weeks ago, Mayor Mike Johnston stood near the jetty at Sloan's Lake and announced $50 million to dredge and restore the lake. If you've lived in the neighborhood for more than a year, that number should stop you. Every conversation about fixing Sloan's Lake for the past decade has circled a much smaller figure. Last November, Denver voters approved a bond package that included exactly $5 million for the lake. The Sloan's Lake Park Foundation had asked for as much as $40 million and been told the real fix, full dredging included, would run closer to $130 million. Then, on September 2, the number went from $5 million to $50 million almost overnight. That jump highlights how the project is being funded.

The Number That Didn't Come From Where You'd Expect

Here's the part that matters if you live near the water: the largest share comes from an existing tax district. The funding breaks down like this, according to the city's own announcement:

The bulk of the money, up to $40 million, comes from a special tax district the Denver Urban Renewal Authority created years ago to redevelop the old Saint Anthony's Hospital site on the neighborhood's western edge. Mayor Johnston described that redevelopment as running so far ahead of schedule and generating so much surplus revenue that the district now has dollars to spare. That surplus gives the district room to contribute beyond the $5 million voters approved for the lake.

Johnston was explicit that the plan requires no new taxes and no general fund dollars. The timing coincided with surplus TIF revenue becoming available.

Why the Lake Got This Shallow in the First Place

The mechanics behind the shallow water aren't complicated, but the scale is worth sitting with. According to the city, many areas of the lake now average just 2.5 to 3 feet deep, down from historical depths of 8 to 12 feet. Two years ago, when an estimated 2,000 fish died over the course of a week from a combination of blue-green algae, heat, and low oxygen, the lake's average depth measured 3.3 feet. Denver Parks and Recreation's own environmental assessment traces the cause to more than a century of stormwater carrying sediment into the basin through 23 unfiltered storm drains, from a watershed that stretches west into Edgewater, Lakewood, and Wheat Ridge. Colorado Parks and Wildlife stopped stocking the lake with walleye, catfish, perch, and trout in January 2024 because the conditions no longer supported them. Catfish and carp still swim there, and fishing is still allowed everywhere except the channel between the island and shore.

As Denverite reported, Parks director Jolon Clark said:

"There are still some approvals that need to happen before anything starts to move forward. So in the very short term, not a lot of changes, but the focus throughout the project will be to keep as much of the park open and usable as possible, doing work in the lake."

Translation for anyone who walks the 2.8-mile loop or takes their dog to the north shore: this isn't closing tomorrow, and it isn't closing all at once when it does start.

What Actually Changes, and On What Timeline

The dredging work itself is expected to take 30 months once it begins, and as of the announcement, it wasn't clear exactly when that would be. The project still needs sign-off from the Denver Urban Renewal Authority board, which officials said could happen as early as mid-September, followed by additional city approvals after that. If you're checking your calendar against that window now, in late September, the earliest procedural step may already be behind us, but there's no public confirmation yet that dredging equipment has a start date.

A few things residents can expect once work does begin:

• Dredging will target the accumulated sediment that's been building for over a century, aiming to restore deeper, colder pockets of water rather than uniform depth everywhere
• Shoreline stabilization and habitat restoration will run alongside the dredging to filter sediment before it reaches the lakebed again
• The city has said it intends to keep as much of the 177-acre park open and usable as possible during construction, rather than closing it wholesale

One thing the announcement does not promise: swimming. Sloan's Lake has never allowed swimming, and Denver's parks department continues to discourage any contact with the water because of bacteria including E. coli that runoff carries into every lake in the city. Kurt Weaver, who leads the Sloan's Lake Park Foundation and has pushed for this fix for years, has said he'd love to see the lake swimmable again the way it was decades ago. That's an aspiration, not a feature of this specific plan. Depth and water contact safety are separate problems, and this $50 million addresses the first one.

The Businesses That Never Waited on Any of This

What makes Sloan's Lake an interesting case is that its restaurant and brewery scene built itself out entirely on a different clock than the lake's decline, and neither one seemed to notice the other. Odell's second Denver taproom, its Sloan's Lake Brewhouse at 1625 Perry Street, runs a 10-barrel pilot system with beers available only at that location, and its rooftop patio points straight at the water regardless of how many feet deep it is. Across Sheridan Boulevard, the Edgewater Public Market has grown into a real food hall destination anchored by vendors like Black Box Bakery and Saigon Noodle Club. A few blocks into West Highland, Paperboy opened its first location outside Texas this spring in the old Rooted Craft space, joining a stretch that already includes Root Down and Linger. ChoLon, the modern Asian restaurant known for its Blake Street location downtown, opened a second location in the neighborhood in 2024.

None of that depended on the lake getting healthier. It still doesn't. The 26th annual Colorado Dragon Boat Festival, one of the largest events of its kind in the country, drew an estimated 180,000 to 200,000 people to the park on August 29 and 30 this year, its usual summer window, after an algae bloom the previous year had forced organizers to push the event into September instead. Organizers have said openly they've considered relocating permanently if lake conditions didn't improve. This year, Denver's health department checked the water the Friday before the festival and found no algae concern, though the lake was running about two feet low from drought. The festival happened because conditions cooperated, not because the fix was already in place.

What This Means If You're Watching the Water From Your Porch

The honest read here is that Sloan's Lake now has three separate infrastructure projects moving on three separate timelines that have nothing to do with each other. There's the $50 million dredging plan, still working through approvals. There's a separate $7 million conversion of the historic boathouse into an event center, funded through a 2021 bond, with construction expected to start later this year and a possible opening as far out as winter 2028. And there's whatever the restaurant and brewery scene does next, which so far has moved faster than either of the public projects.

If you live near the lake, the practical takeaway isn't that everything is about to change at once. It's that the $50 million plan combines a real estate district's surplus revenue with wastewater-fund and bond dollars.
