Robinson Creek in Boonville, California, had highly eroded stream banks prior to initiation of a stream restoration project.. Stream restoration or river restoration, also sometimes referred to as river reclamation, is work conducted to improve the environmental health of a river or stream, in support of biodiversity, recreation, flood management and/or landscape development.
One well-known example of a large-scale stream restoration project is the Kissimmee River Restoration Project in central Florida. The Kissimmee River was channelized between 1962 and 1971 for flood control , turning a meandering 167 km (104 mi) of river into a 90 km (56 mi) drainage canal. [ 19 ]
Cheonggyecheon in 1904. The stream was named as Gaecheon ("open stream") after the first refurbishment project to construct a drainage system during the Joseon period. The work, which included dredging and bolstering the banks of the stream and building bridges, was carried out every 2–3 years during this period from the reign of Taejong, the third king of Joseon.
The bigger undertaking was the stream restoration, and a town YouTube video about the project in 2021 explains that the stream had been a growing concern over the years.
With a $500,000 grant for stream restoration from the U.S. EPA, the University of Louisville Stream Institute bulldozed the 4,000 feet (1,200 m) riparian corridor of Wilson Creek in order to return a meandering course to the channel which had been straightened in the past to allow for farming. Native trees and wildflowers were planted, and fish ...
CVC worked collaboratively with the landowners to design and construct a new stream, stream-side grassland and wetland in 2017. The project improved biodiversity and ecosystem health. Nine species of fish have been recorded in the stream, and Bobolink and Eastern Meadowlark (both threatened bird species) use the planted riparian grassland.
Stream restoration focuses on improving habitat for trout and other cold water species, including aquatic insects. Tactics can include planting trees and shrubs along streams to reduce erosion while also increasing shade, strategic addition of boulders or trees to provide cover and improve water depth and flow, and removing or improving ...
A large reason for stream restoration is to remove nitrogren and phosphorus pollution. Excess nitrogen and phosphorus from anthropogenic activities have partaken in stream and river quality concerns such as drinking water contamination, hypoxia, and algal blooms. [10] There are different approaches one may take to offset these effects.
