The reservoir impounded by this dam is managed by the Thailand Royal Irrigation Department (RID) for the benefit of diverse farm communities below. The US Department of State sponsored the workshop, led by the US Army Corps of Engineers and USGS for the benefit of RID. 

 

Subject matter experts Ariele Kramer and Zulimar Lucinda (KS WSC and OK-TX WSC, respectively) shared their experience and insights with USGS water-quality sampling techniques, data standards, and data interpretation with RID counterparts. Matthew Andersen from USGS Office of International Programs organized and administered the engagement for USGS. 

Three days of site visits and four days of classroom instruction were employed for the exchange. USACE colleagues shared their experience and insights with sediment management, especially in reservoirs, to complement the USGS material, providing a robust U.S. Government training experience for which RID expressed deep gratitude. 

The workshop ended with consensus about a series of additional training and workshops that RID would like to receive, subject to availability of funds.
