The new film In the Heart of the Rockies debuts tonight on the Sportsmans Channel. The film is the latest from the duo Conservation Hawks and Conservation Media, who brought us the films Convergence, Chrome and, most recently, Cold Waters—all films which explore the impacts that climate change is having on watersheds, fish and anglers around the globe.

The grass and sand flats of the Lower Laguna Madre might be the most productive flats system, outside of the Florida Keys, in the contiguous U.S. But that doesn't mean the fishing is easy, especially in the winter, when finicky weather and colder water temperatures make redfish and speckled trout much more wary.
