By the 1870s, a steam engine powered pump known as the "Dublin Street Machine" at the back of the Carrollton neighborhood was used to drain that neighborhood, pumping the water out the Upperline Canal. Use of the canal to pump water from the streets of the city into Lake Pontchartrain grew with the city. The Claiborne Canal connected with the 17th and Upperline Canal system via a canal along Dublin Avenue; thus the canal served to carry rain water to the lake from the majority of Uptown New Orleans above the New Basin Canal. Another canal, Hoey's Canal, was added connecting to the Upperline from up river to help drain the back of the Jefferson Parish communities along the riverfront, now known as "Old Jefferson".
