[1] A major artificial distributary on the left bank of the Tamsui, the Erchong Floodway, was completed in 1984 as part of a flood control scheme for the Taipei Basin.

The flood control plan for Greater Taipei dated back to 1959, and by 1987, dykes had been built along the banks of the Tamsui.

Clean up and natural river restoration is on the agenda of the Taipei City Government, Executive Yuan and several citizen organizations.

[8] Governmental efforts to clean up the Tamsui include "The Recovery Project of the Tamsui River Watershed Area" implemented in 1987 by the Environmental Protection Administration, at the time a division of the Department of Health.

[10] Cleanup efforts continue to the present day, and include linking the watershed's residents to a shared sewer system.
