Straw Wattles:

• filter stormwater runoff water
• spread overland waterflow
• trap sediment to prevent erosion
• prevent erosion by reducing slope lengths and slowing and spreading water flow.
• diminish storm water runoff pollution by capturing sediment.
• enhance revegetation of slopes denuded by fires and timber harvest.
• reduce sheet erosion and prevent rill and gully development.
• impede sediment transport into waterways
• are more efficient than silt fences and don't have to be removed.
• are velocity dissipation devices
• work as check dams to prevent sheet erosion as well as rill and gully development.
• are level spreaders
• abut end to end tightly and do not leak between wattles
• can be laid along the edge of the sidewalks to keep soil on site and prevent it from washing onto pavement and asphalt
• can be wrapped around storm drain inlets to slow water and settle out sediment
• capture sediment and spread water rather than concentrating the flow and volume

Straw Wattles last 3 to 5 years and can be left in place. They replace silt fences, straw bales, earth berms, willow wattles, sandbags, and earth water-bars. Used with tacked straw they are an efficient and cost effective replacement for erosion control blankets.
