The Times podcast: Colorado River in Crisis, Pt. 6: The End

Conservationist Mateo Sanchez uses a net to collect specimens in a Colorado River Delta estuary. A release of water from the canal into the riverbed began in May 2022 and reached parts of the delta that are normally bone dry. The flow is part of a recent amendment to the Colorado River Compact that allots river water for restoration, conservation and scientific efforts in Mexico.
