<br />NOTES
<br />1. Natural flows reflect only water which originates in Colorado. Thus, 248,600 of of Little Snake flows originating
<br />in Wyoming and 259,800 of of San Juan River water are not included.
<br />2. Ag and Evaporation values have not exceeded the maximum values recorded during the 1981 -85 period.
<br />3. Exports reached an all time high in 1978.
<br />Through 1994, annual exports from the Colorado have not exceeded this value.
<br />4. Maximum M&I values from U.S. Geological Survey WRIR 884101, all other values from US. Bureau of Reclamation
<br />Consumptive Uses and Losses Report.
<br />do include depletions from exports column must be added into compute the total
<br />5. Depletion values not exports,
<br />depletions occurring from a basin.
