Wetlands not only slow water, but they help to purify water by allowing it to move slowly. Plants and gravity do a wonderful job of cleaning water on its way to the sea. On top of that, forested land is more conducive to rainfall. By allowing these areas to flourish, you not only slow and retain water but increase catchment overall as well. The chance of forest dying in drought decreases, and your chance of rainfall increases (slightly, yet meaningfully when balances are so delicate). Beavers also produce habitat which benefits many other native species. More water is generally more life in North America.
