from entering the strainer. The strainer and intake hose can be secured to a post or pile
(see figure 6-2). In water less than 4 inches deep, a pit can be dug to increase the
depth (see figure 6-3). The screen is surrounded by gravel to prevent collapse of the
sides of the pit, to shield the screen from damage by large floating objects, and to act as
a coarse strainer. A bucket may also be used to protect the intake screen. An
improvised dam may also be constructed to increase the depth of water in a stream.
