The system of drainage channels and natural stream channels in the Albuquerque metropolitan area is a source of concern because of potential local flooding and water-quality problems. Rapid urbanization since 1970 has increased precipitation runoff to these channels, which in many instances return flow to the Rio Grande. As an important element of the City of Albuquerque’s water-...
