For example the <br />"ISF Water Rights where Water Availability may <br />have bad a Role in Appropriation" coverage could be <br />overlaid on the "Flannelmouth Sucker Distribution" <br />coverage. If there are areas where there is <br />comparability between the two data layers, then it <br />may indicate an area of priority for investigating ISF <br />or habitat considerations.

The Stream and Lake <br />Protection Section manages a database that contains <br />information on all ISF and natural lake level <br />appropriations and proposed appropriations, which <br />are held by or that are being evaluated for <br />appropriation by the CWCB. This database was <br />used to prepare three coverages: <br />~ A map of the approximately 8,500 miles of <br />streams that are part of the ISF Program (for an <br />example see <br />http://cwcb.state.co.us/Streamandlake/Images/ <br />StatewideISFinap.jpg) (Figure 4-3). <br />~ A map of CWCB's natural lake levels water rights <br />(Figure 4-4). <br />~ A map showing ISFs where water availability may <br />have bad a role in the appropriation (Figure 4-5). <br />CWCB Instream Flow/ Coverages The first two coverages were prepared by simply <br />CWCB, acting through the Stream and Lake querying the database for streams and lakes that <br />Protection Section, bas exclusive statutory authority currently have ISF and lake level water rights and <br />to appropriate water to preserve the natural then mapping each waterbody.
