<br />47. REMARKS AND RE~ERENCES
<br />
<br />In May 1984, Reclamation recomputed the area and capacity of Pueblo Reservoir using the cubic spline option of
<br />the Bureau of Reclamation program ACAP. The original surface areas were used as input data.
<br />
<br />Estimated noncontributing area lnto reservoir. Sediment inflow is affected by several upstream reservoirs such
<br />as Turquoise Lake, Twin Lakes, Clear Creek Reservoir, De Weese Reservoir, and several other small reservoirs
<br />and diversion structures.
<br />
<br />Calculated inflow to Pueblo Reservoir for water years 1974 through 1993.
<br />drainage area plus diverted water from the western slope.
<br />
<br />Runoff contributed by 4,669-square-mile
<br />
<br />Surface area and capacity at spillway crest elevation 4898.7. For sediment computation purposes, the original
<br />capacity was recomputed uSlng the segmented least squares fit option of the Bureau of Reclamation program ACAP.
<br />This option is the current method used by Reclamation. The original surface are~s were used as input data.
<br />
<br />1993 surface area and capacity at spillway crest elevation 4898.7. The 1993 area and capacity tables were
<br />computed using the segmented least squares fit option of the Bureau of Reclamation program ACAP. This option
<br />is the current method used by Reclamation.
