Stream Restoration

Habitat Type

A stream, also known as a branch, creek, run, or brook, is a continuous surface flow of freshwater within a channel that is smaller than a river. Headwater streams can originate from groundwater (springs), runoff, or a wetland. Streams and rivers flow more than 3.5 million miles across the United States and are present in every region (EPA 2013). Streams are generally too small to have their own floodplain and run at steeper gradients and faster velocities than rivers, resulting in a greater amount of dissolved oxygen (USGS 2018). Nationally, stream health is declining as a result of an increase in impervious surfaces, polluted stormwater runoff, nutrient pollution, drought, deforestation, and physical barriers. As a response to this decline, communities are working to restore streams, with more than $1 billion a year spent on stream and river restoration in the United States (Bernhardt et al. 2005). Stream restoration techniques fall into two categories: form-based (which is more common) and process-based (Roni et al. 2002). Common techniques include brush layering, coir log installations, cross vanes, grading stream banks, log vanes, J-hooks, and step pools (MCDEP 2023).
