===The check dam idea is an interesting one...I got it from Brad Lancaster's stuff :http://www.harvestingrainwater.com/ . It makes a lot of sense, especially when you realize that most of a water flow like a river of stream is actually underground and slower...and if you slow a bit of the upper water, it extends the time the water is in the system.
