Logjams occur naturally and can provide beneficial stream structure and cover for fish and wildlife as well as contributing to nutrient-rich sediment being deposited on adjacent floodplains. In many cases, the ripples caused by obstructions oxygenate the water to improve water quality. However, streams are also expected to function as efficient drainage outlets, conveying water off the land in a timely manner. Logjams may inhibit this drainage function resulting in increased flooding, destruction of property, negative impacts on some wildlife habitats, and increased erosion and sedimentation.
