A water permeable erosion control bag, comprising:a container having a flexible mesh wall with openings through which water can flow through the bag; anddiscrete wood fragments loose within the container, wherein the wood fragments do not have smooth surfaces that tend to stick together when wet and form a mass of fragments that prevents flow of water through the bag, and the wood fragments resist adhering to other wood fragments within the container without becoming clogged with sediment carried by the water, and wherein the wood fragments are large enough to be retained within the mesh wall, and the mesh wall allows a flow of water through the bag, wherein the wood fragments are not retained by a separation screen having a screen opening of about 11/2 inch, so that the wood fragments within the container are smaller than 11/2 inch.
