The railroad infrastructure in Krasnoselsky District, a steady source of municipal revenue, was threatened by regular floods on numerous tributaries of the Yauza. This risk, along with the drive to free up land for development, led to the first modern flood control measures in the Yauza basin. Red Pond (), connected to the Yauza by the Chechora River, was drained and converted to municipal rail yards in 1900–1911. During the same period, the Chechora was diverted into an underground sewer and the Yauza was spanned by new bridges.
