 | | Rivers offer areas for swimming, boating, fishing, or waste disposal, and sources of water for generating energy, drinking, snowmaking, irrigating crops or fighting fires. |
 | | As the river flows downstream, some organic material is stored (as insect or animal tissue), some is cycled (changed to different forms), and some is released. |
 | | Above the dam, water velocity is slowed, causing soil particles and organic material to settle to the bottom and cover the river bed with mud. |
