Resilient waterways
Restore circulation and care for the water that supports our neighborhoods and natural systems.
Harlingen’s resacas are part of our landscape, our history, and our future. Together, we can restore clean, connected water for people, wildlife, and the generations that follow.
The Harlingen Resaca Restoration Project works to restore and maintain the resacas of Harlingen, Texas. We recognize the habitat created by these waterways as a valuable community asset and an important refuge for migrating shorebirds and other wildlife.
Formed by the receding waters of the Rio Grande River, these water features are part of the Arroyo Colorado watershed and a unique ecosystem. We will work to identify practical, lasting ways to maintain water levels on an ongoing basis.
KRGV reported on the community effort that became the Harlingen Resaca Restoration Project after the resaca nearly dried up this summer. Neighbors are pursuing nonprofit status and engineering studies to identify a long-term way to sustain water, protect wildlife, and meet drainage needs.
