The lakes were created by deep gravel mining operations before the land was repurposed for public recreation.
The park is named after Dr. Ada Hayden, the first woman to earn a PhD from Iowa State University and a prominent botanist.
The water depth in the main lake reaches 50 feet, making it significantly deeper than typical natural glacial lakes in the region.
The park includes an 'island' area accessible via a pedestrian bridge that offers elevated views of the wetland.
The site acts as a functional retention basin, protecting downstream neighborhoods from storm-water runoff.
Ada Hayden Heritage Park is a 437-acre site in Ames, Iowa, primarily defined by two reclaimed gravel quarry lakes that reach depths of up to 50 feet. The park is managed by the City of Ames and functions as a managed wetland ecosystem designed to prevent floodwaters from reaching residential areas. It features a paved 2.8-mile trail that encircles the main lake, providing access for hikers, cyclists, and joggers. The site serves as a regional habitat for diverse bird species, including bald eagles, pelicans, and various waterfowl. Fishing is permitted in the designated lake areas, which are stocked by the Iowa Department of Natural Resources. The park encompasses a mix of restored prairie, oak savanna, and wetland vegetation zones. It is situated on the north side of Ames and is connected to the city's broader trail network.

Bring binoculars as the elevated berms provide excellent vantage points for spotting migrating shorebirds.
The paved trail is fully exposed to the sun; wear sunscreen and bring extra water during mid-summer visits.
Check the Iowa Department of Natural Resources fishing regulations for specific species and limits before casting.
Do not attempt to swim in the lakes, as the deep, cold drop-offs and steep banks present significant safety hazards.
Leash your dogs at all times and pack out all trash to maintain the wetland habitat.
