another good water management resource = Let the Water Do The Work
Procedure: Put up a speed bump. Sediment collects on the upstream side of the speed bump. Periodically use the sediment to widen the base of the speed bump and to make it taller.
As a means to control the water from the run off creek that is home to the permaculture island of food we've been developing, 8 small dams have been placed upstream from our garden since last spring. We have used a modified version of the one rock dam as the theory behind these structures. Our food island did not flood even once this year, last year it was entirely under water multiple times. These 8 little speed bumps are distributed over the course of about a 1/4 of a mile of sometimes step run off. They have been started with minimal effort and as the sediment collects behind the small obstruction it is piled on top and used to widen the base of the dam. These photos were taken today after the last sediment redistribution of the year. It has not rained for about 5 days. Click the images to enlarge the photos. Procedure: Put up a speed bump.

Looking good. It was so great that the garden didn't get flooded this past summer.
