Santa Fe, New Mexico is a city of arroyos. More than 80 miles of these ephemeral waterways enter the main Santa Fe River that flows through the city. But many of the arroyos are ailing. Years of erosion and general neglect have worsened flooding during storms, leading to a lot of damage. Now, the nonprofit group Santa Fe Watershed Association has launched a recovery program called Adopt-an-Arroyo. It’s patterned after the group’s thriving Adopt the River program, in partnership with the city and county of Santa Fe.
