Great Lakes Aquarium | Duluth

Great Lakes Aquarium – Duluth, Minnesota
A freshwater-focused science center on the shores of Lake Superior, blending environmental education, conservation, and immersive exhibits

1. Introduction

The Great Lakes Aquarium (GLA) is a unique, interactive, and freshwater-dedicated facility located on the Duluth waterfront near Canal Park. Opened in 2000, it is one of the few aquariums in the world with a primary focus on freshwater ecosystems. The building spans approximately 62,000 square feet and is home to more than 1,500 animals across 250 species, most of which are native to the Great Lakes Basin, the Amazon River, and other large lake systems around the globe.

The aquarium’s mission is to “inspire stewardship of freshwater resources and ecosystems”, a goal fulfilled through live animal exhibits, science education programs, and conservation outreach.

2. Building and Layout

The aquarium is designed across two main levels, connected by elevators and wide ramps, making the entire facility fully ADA accessible. The architecture features large curved glass panels and an observation deck that offers expansive views of Lake Superior, the Aerial Lift Bridge, and the Duluth Harbor.

3. Signature Exhibits

A. Isle Royale Exhibit

The centerpiece tank, holding 85,000 gallons, is visible from both floors.

Modeled after the Lake Superior waters surrounding Isle Royale, it contains native species.

The exhibit mimics deep lake conditions with dim lighting and underwater structures.

A glass viewing tunnel lets guests walk beneath the surface level.

B. Baptism River and St. Louis River Galleries

These replicate northern Minnesota river ecosystems with flowing water, log jams, and gravel bottoms.

These habitats are used to explain watershed dynamics and sedimentation.

C. Otter Cove

A major attraction for families, this is a naturalistic habitat for North American river otters.

The otters, named Agate and Ore, can be seen swimming, sliding, and playing both underwater and above ground.

The habitat includes a waterfall, sandbars, and educational panels about the otters’ native range, behavior, and conservation.

D. Unsalted Seas

Opened in 2016, this gallery explores other large freshwater lakes of the world.

It includes a touch pool for sturgeon, one of the largest of its kind in the U.S.

E. Amazing Amazon

Tropical rainforest setting with vibrant and exotic freshwater species.

Rainforest soundscapes and humidified air enhance immersion.

F. Origins and Aquatic Invaders

Origins traces the development of aquatic life through Earth’s early history, showcasing:

Ancient fish fossils

Amphibians

Corals and invertebrates

Aquatic Invaders educates about non-native species disrupting the Great Lakes, like:
