Lake Mead sits at record lows, and Las Vegas planners warn the taps could run dry within twenty years. Rather than another concrete dam, this film follows scientists and water managers looking at an unlikely fix: beavers. Their dams slow and spread water across a landscape, recharge groundwater, and create wetlands that survive drought far better than engineered channels. Footage tracks beaver-built ponds in the Mojave region and interviews with hydrologists and ecologists who explain how a single 30kg rodent reshapes a watershed more efficiently than heavy machinery. The film lays out the scale of Las Vegas's problem, a city of two million people drawing almost all its water from a shrinking reservoir, and contrasts that with small-scale beaver reintroduction projects already showing results elsewhere in the American West. It's a practical case for treating an animal most people consider a nuisance as genuine infrastructure, built on interviews and location footage rather than speculation.
