Way I see this being used it to "dam" up the river. From the pooled area you have made what OKIE posted as a Water Catch System. Just like you do at your house with Rain Barrels. You can do the same thing at your house with a large water tank and make a gravity feed watering system. Say for you garden or yard.
Here in Astan if your VSO is close to a dry river bed that gets water when it rains or rains in the Mountains of Zabul. Well you make these "dams" or "walls". In turn you are slowing the water down. From a "pool" you can use CERP and buy shovels and picks and have the locals dig a irrigation ditch to the field area. Buy some Gas water pumps and you just open up the farm land with water for better farming. Many other ways of making ditches but I think a 18C can think up at nice fun & fast way. Then get the locals in to clean it up and make their mud walls to act as weirs.
