Abstract
A ditch check for controlling erosion or sediment run-off in a ditch or swale is configured as a generally planar panel. The panel has suitable water-conducting passages to permit and is given holes to insert anchor stakes to anchor the panel to the ground. The panel is preferably made substantially of a polymer or resinous moldable material. The panel is given such formed side edges that adjacent panels can overlap or enmesh one another where they meet to close a gap therebetween. It is optional that the panel be stackable with other like panels, for greater convenience during non-use periods, as while being transported and/or during storage. Given the foregoing, the panel is meant to replace straw bales as ditch checks because the panel is very much lighter, is non-absorbent and inexpensive, and is indefinitely reusable.
