Land & Water Restoration Workshop – Buenos Aires Wildlife Refuge, Arizona

March 20 - March 25


March 20-25, 2023


Please join the Altar Valley Conservation Alliance (AVCA) and restoration experts Brad Lancaster, Omar Ore-Giron, and Kyle Thompson as we restore arroyos on the Buenos Aires National Wildlife Refuge. Throughout the week, we will:

  • Learn about site assessment and design techniques applicable in rural and urban settings
  • Build rock & brush grade-control, water harvesting, & induced meandering structures (one-rock dams, baffles, etc.) in the Puertocito Wash
  • Maintain existing structures at the Arroyo Hondo Wash using innovative rock and brush techniques
  • Conduct monitoring of stream morphology and vegetation
  • Work in a system where roads, tanks, and arroyos are modified together to harvest rainwater

Practitioners and volunteers are welcome for this free workshop any and all days from March 20-25. Camping is available on the Refuge.


Hands-on land & water restoration workshop in Buenos Aires Wildlife Refuge – SW Arizona

This is a great opportunity to get some hands-on experience with placement, design, and construction of water-harvesting erosion control and induced meandering structures in different sized arroyos to reconnect these downcut waterways with their floodplains for greater water spread and rehydration. In addition, we’ll cover rolling dips—a strategy that diverts water off dirt roads where the water can do maximum good in the adjoining landscape.

These strategies work great in BOTH the urban and rural setting. If you aren’t familiar with them, here is your opportunity to change that. Every water harvesting practitioner should know when and where to use these structures and how to effectively hybridize them when appropriate.
