AMES — Iowa State University officials are restoring Lake LaVerne, a human-made body of water on the campus. The project involves dredging sediment, adding new features, and reintroducing wildlife.

University officials drained the lake and removed its wildlife prior to July 2026. A turtle-catching event moved amphibians to a safer area for construction. Workers began dredging the bed of Lake LaVerne in early June 2026. This process has not been completed since the 1950s.

During dredging on June 25, 2026, a rusted, several-foot-long cannon was discovered in Lake LaVerne. The origins of the cannon are unknown. Claire Vorthmann, Facilities Construction Manager at Iowa State University, stated that it might be the cannon used to celebrate football touchdowns before it was stolen from the Alpha Sigma Phi fraternity in the early 1970s. Other items removed include a bowling ball, bicycle parts, and glass bottles. One glass bottle from ABC Brewing, which is now closed, was found. The bottles date to the 1940s and 1950s.

Sediment accumulation had reduced the maximum depth of Lake LaVerne from 12 feet to 6 feet. The goal of the current dredging project is to restore the lake to its original planned depths. Upon completion, the lake is projected to have an average depth of 5 feet with areas reaching 13 feet deep. Close to 500 truckloads of sediment have been removed, and Vorthmann estimates the total sediment removal will reach approximately 1,200 truckloads.

Chris Strawhacker, campus planner for real estate and capital planning at the university, stated that deeper water improves habitat for fish and animals and enhances water quality. He added that deeper water reduces the chance of algae blooms. Portions of the lake bed will be made shallower to function as spawning beds. Once the restoration is complete, Lake LaVerne will be restocked with fish.

The restoration project also includes reshaping the north shore for a new pathway and seating areas. West shore improvements, including a bridge and amphitheater, are in the design phase. Strawhacker noted that student surveys indicated most people pass by the lake without sitting to enjoy it. The plan is to create spaces where people can spend time and appreciate the lake. Vorthmann reiterated this sentiment, stating she looks forward to seeing the lake area used for more than just a path to the Memorial Union.

Lake LaVerne has been home to swans, often named Lancelot and Elaine, since the 1930s; however, some pairs have been female. The tradition ended in 2022 when one swan died and the other was relocated. Plans are in place to introduce a new pair of swans to Lake LaVerne after the restoration is complete.
