Colorado River from headwaters to the delta

LAS VEGAS, NEVADA - APRIL 14: Tourist takes gondola rides at The Venetian Resort on April 14, 2023 in Las Vegas, Nevada. The resorts has water filled canals inside and outside acting as a reproduction of the canals of Venice, Italy. The Venetian Resort in Las Vegas is not built on the water like Venice, Italy. No, it was built in the desert of Nevada where water is scarce. As the Colorado River dwindles due to climate change the City of Las Vegas is becoming an unlikely model for water conservation in the west as water officials meet water demand for growing population amid drought.
