Over the past 20 years, quadrillions of invasive mussels have been sucking the life out of the Great Lakes. They’re trapping nutrients, the basic building blocks of life, on the lake bottom. Without nutrients, organisms of all kinds – from the tiniest plankton to the largest fish – are vanishing. In Lakes Huron, Michigan, and Ontario, vast offshore areas have become “biological deserts,” heralding one of the biggest changes to the Earth’s freshwaters in 10,000 years.

All Too Clear uses cutting-edge underwater drones to explore how quadrillions of tiny invasive mussels, known as quaggas, are re-engineering the ecosystem of the Great Lakes at a scale not seen since the glaciers. To capture this epic change, the Canadian husband-and-wife filmmaking team of Zach Melnick and Yvonne Drebert spent more than 150 days filming underwater, making it the most ambitious underwater film ever made about the Great Lakes. Part scientific exploration, part natural history adventure – the film showcases freshwater wildlife and environments like never before.

This epic documentary will challenge everything you think you know about the world’s largest freshwater ecosystem, and its tremendous potential for the future.
