Our planet’s greatest freshwater ecosystem, like you’ve never seen it before
TVO Original, 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 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.

While filming All Too Clear, we found a shipwreck. Read about it on Canadian Geographic, and watch the video below.
Although numerous divers were filmed for the TVO Original All Too Clear, none were actually used to capture the underwater footage in the series. Instead, filmmakers Yvonne Drebert and Zach Melnick relied on an advanced underwater drone, or Remotely Operated Vehicle (ROV), to explore beneath the surface of the Great Lakes. In this video, they share insights into the technology behind the ROV and its role in the production, with a surprise cameo by a curious beaver.
