Flood Protection and Erosion Control:
Floodplains provide a river more room as it rises. They accommodate temporary
storage of flood water, reducing flood peaks and erosion potential.
Improved Water Quality: When inundated with
water, floodplains act as natural filters, removing excess sediment and
nutrients. Outside of a river's main channel, water flow is slowed and has more
time to seep into the ground where it can replenish underground water sources.
Improved Wildlife Habitat: Floodplains are
home to some of the most biologically rich habitats on Earth, including marshes
and wetlands. They provide spawning grounds for fish and critical areas of rest
and foraging for migrating waterfowl and birds.
Recreational Opportunities: Many outdoor
recreational activities – like fishing, hunting, camping, hiking, wildlife
watching and boating – are made possible by and greatly enhanced by the natural
processes of rivers and healthy floodplains.
