Harbor Fest turns 10 this Sunday, and the free waterfront celebration at Harbor View Plaza features boat tours, a tugboat visit, and a baby sturgeon release meant to get families thinking about what swims beneath the surface of the city's rivers. The event runs from 11 a.m. to 3 p.m. and is open to all ages, with this year's theme, “What Lies Beneath,” built around exploring Milwaukee's waterways.
According to WISN, Harbor District CEO Tia Torhorst joined the station's 12 News at 11 broadcast to preview the festival ahead of Sunday's celebration.
A Park Built From Industrial Land
Harbor View Plaza itself, located at 600 East Greenfield Avenue, has only existed as public space since it opened in July 2019, following a 2016 design competition, per Milwaukee Independent. The park is a new public space and includes a water-play area along with an accessible kayak and canoe launch, the outlet notes.
Harbor District, Inc., a nonprofit created in 2014, works to support redevelopment in the area.
Sturgeon Return After a Century Away
This year's baby sturgeon release ties directly into one of the region's longer-running conservation stories. Between 2006 and 2026, the “Return the Sturgeon” restoration initiative between Riveredge Nature Center and the Wisconsin DNR saw more than 19,000 young lake sturgeon survive and get released into the Milwaukee River watershed, according to WUWM 89.7 FM. The station reports that lake sturgeon disappeared from the river due to factors including overfishing and degraded habitat; adult male fish were documented upstream in 2026, though it remained uncertain whether females would arrive.
Wisconsin regulators still treat the species carefully. Under Wisconsin Department of Natural Resources rules, lake sturgeon face strict hook-and-line harvest limits requiring a minimum size of 60 inches in designated open waters, and anglers must purchase special tags, validate them immediately, and register harvested fish at an official station, as previously detailed by Hoodline's coverage of the 2025 season.
Art, Open Houses, and a Bigger Riverwalk
Beyond the water, the 10th anniversary event features a temporary art installation housed inside a shipping container created by artist Madison Boeder, live painting by artist Bigshot Robot, and open-house tours at the adjacent University of Wisconsin-Milwaukee School of Freshwater Sciences as part of Doors Open Milwaukee, per the Milwaukee Neighborhood News Service. This year's festival also coincides with Doors Open Milwaukee.
Just south of the plaza, the waterfront footprint keeps expanding. In July 2026, Milwaukee Mayor Cavalier Johnson and Harbor District leadership held a ribbon-cutting for Phase 1 of the Harbor District Riverwalk along the Kinnickinnic River near Komatsu Mining, according to FOX6 Milwaukee. The station reports the new multi-use path includes native landscaping, public seating, and displays of heavy mining equipment built locally.
The Bigger Cleanup Behind the Celebration
The festival's aquatic theme sits atop a much larger remediation effort. Cleanup work in the Milwaukee Estuary Area of Concern includes sediment dredging to address historical pollutants.
Not every part of the district's waterfront push has gone uncontested. A proposed office development at 350 S. Water St. and public-access requirements for the riverwalk system have become part of the waterfront debate. For now, though, Sunday's celebration at Harbor View Plaza is free, family-friendly, and squarely focused on the water itself, from tugboats to the sturgeon swimming just beneath it.
