<br />Precipitation Data
<br />Staff reviewed a local precipitation data set from one site located around Pueblo Reservoir (See
<br />Precipitation Data and Map in Appendix). This data indicates that the 17 years of stream-flow
<br />data (Arkansas River at Moffat Street gage) is representative of average water-years.
<br />
<br />Existing Water Right Information
<br />Staff has analyzed the water rights tabulation and consulted with the Division Engineer's Office
<br />(DEO) to identify potential water availability problems. Surface water diversions within this
<br />reach of the Arkansas River are: West Pueblo Ditch, Commanche Pump Station (SCPC), Pueblo
<br />Board Water Works Ditch, PBWW Northside Ditch, PBWW Southside Ditch, Harp Tailwater
<br />Right and SCMWD Pump Station Nos. I and 4. According to the DEO, there is usually
<br />sufficient water available within this stream reach to satisfy the recommended instream flow
<br />amount. Staff believes that water is available for appropriation on Arkansas River based on an
<br />analysis ofthe gage data and staffs consultation with DEO from the outlet ofthe fish hatchery to
<br />
<br />.
