Human control has resulted in a decrease in spring floods and a reduction in the amount of sediment carried by the river. This has resulted in the gradual deepening of the river channel, further reducing the likelihood of flooding, making it difficult for tree and willow roots to reach water, and inhibiting the germination of new seedlings within the riparian habitat.
