Side Channel / Floodplain Reactivation
What is The Freshwater Trust doing here?
More than 50 years ago, the Zigzag River, a tributary of the Sandy, was straightened, leaving little to no floodplains or side channel connectivity. Many tributaries in the region were similarly straightened because, at the time, it was believed that this action would reduce flooding downriver.
Working with partners, The Freshwater Trust (TFT) has spent over a decade trying to return the Zigzag and other tributaries to their meandering natural state, which is healthier for the river system, fish, wildlife, and it provides better protection against flooding.
By installing large wood structures throughout the project and reintroducing water flow to historic side channels, TFT and partners have reactivated the floodplains, slowed down the water flow, and created desperately needed spawning and juvenile-rearing habitats for native fish species.
Why is this important?
Believe it or not, floodplains are vital for the economy and the environment.
They reduce flood risk by providing temporary buffer zones to store floodwaters when the rivers rise. Floodplains also filter surface water, helping to improve water quality. Agriculture relies on floodplains for growing crops because the soil is often nutrient-rich.
Floodplains also offer a variety of habitat types for wildlife and aquatic species, supporting biodiversity. Humans also enjoy floodplains for their recreational value, including activities like fishing, birdwatching, and boating.
