Two factors stand out as reasons to include tributary basins when discussing
the flow of water within the Snake River. First, the majority of recharge occurs
within the tributary basins. Second, the large areas associated with the tributary
basins provide opportunities for development and use of water within the tributary
basins themselves. Use of water within a tributary basin can affect the quantity
and timing of water availability to the Snake River.
