Over 40 turtles were rescued from a dying Pennsylvania lake in 2025; now, after a massive cleanup, they’re finally returning to the water they once called home

After an extensive restoration effort which turned a polluted water body into one that would support life, 49 musk turtles have been reintroduced into Crystal Lake in Pennsylvania where the animals were previously living. They had been taken out while the water body was being dredged in 2025 after years of being affected by sediment building and water-quality problems.

Crystal Lake, situated in Carsonia Park close to Reading, was highly affected by sediment build-up by the time of the restoration project. As per the Aark Wildlife Rehabilitation and Education Center, the amount of build-up had made parts of the lake “about three feet deep deep instead of its natural 10ft,” resulting in algae problems and oxygen depletion. There were also water quality and aquatic habitat improvement as goals in the restoration efforts.

According to the Mount Penn Borough Municipal Authority's restoration plan, there was storm water improvement, dredging, construction of a wetland and other efforts for the improvement of water quality and aquatic habitat as well as protecting the drinking water source for the local area in the Antietam Creek and Schuylkill River watershed.

Residents discovered dozens of dead animals

The environmental damage became especially apparent when the lake was drained for the work in 2025. Residents found dead fish, turtles, crayfish and large numbers of snails exposed in the muddy lakebed.

Local resident Lori Lilley told PEOPLE that she and others found more than 30 dead turtles, along with numerous fish and hundreds of dead snails. She and her husband subsequently began searching for surviving turtles and transporting them to Aark for rehabilitation.

Only four living turtles were found during the first two days of the rescue effort, according to the account, but continued searches uncovered additional survivors. Aark, a Pennsylvania wildlife rehabilitation organization that cares for more than 5,000 animals annually, provided veterinary and rehabilitation support.

Turtle rehabilitation helped rebuild the population

The rescue effort extended beyond caring for adult turtles. Aark reported incubating and hatching around 25 musk turtle eggs during the project, adding another generation to the animals affected by the lake's restoration.

The other turtles were dealt with individually while work was ongoing. Permission from the Pennsylvania Fish and Boat Commission to release the snapping and painted turtles in the nearby Antietam Lake was granted to Aark, while musk turtles stayed at the rehab center.

Reintroduction started in March 2026 and 49 musk turtles were released in Crystal Lake on September 27, 2026. This is a crucial step in a restoration process which seeks not only to restore the lake itself, but also its underwater habitat.
