Attachment 3 <br />PROPOSED PRIORITIZATION CRITERIA FOR <br />COOPERATIVELY FUNDED STREAMGAGES IN COLORADO <br />Goal 1-- Quantify Streamflow in Major Colorado Watersheds <br />3 points - -Gages on major rivers (North Platte, South Platte, Arkansas, Rio Grande, San Juan, Animas, <br />Dolores, Gunnison, Colorado, White, and Yampa) that have a > 20% change in annual flow from <br />downstream gage(s). Gages are selected by beginning with state -line gage and moving upstream until <br />flow is less than 5% of the flow at the gage that has the largest average annual flow on that river. <br />2 points - -Gages on tributaries to major rivers: 1) Up to three gages on very large tributaries (tributary flow <br />is > 20% of the flow at the gage that has the largest average annual mainstem flow); 2) Up to two gages <br />on large tributaries (tributary flow is > 20% of the mainstem flow upstream from the tributary); or 3) One <br />gage on medium tributaries (tributary flow is > 10 % of the mainstem flow upstream from the tributary). <br />1 point - -One gage on small tributaries (tributary flow is > 5% of the mainstem flow upstream from the <br />tributary). <br />0 points--All other gages. <br />Goal 2-- Support Colorado Flood and Water - Supply Forecasting <br />3 points- -Gage is an NWS, COE, USER, State, or local flood forecast gage. <br />2 points - -Gage is an NRCS or NWS water - supply forecast gage. <br />1 point - -Gage is a State or local water - supply forecast gage. <br />0 points--All other gages. <br />Goal 3-- Support Colorado Water Administration and Management <br />3 points - -Gage is a National Streamflow Information Program (NSIP) `Compact or Border' gage or is <br />needed to administer water to meet interstate compact requirements. <br />2 points- -Gage is critical for water administration or is a key gage for water administration within a water <br />division. <br />1 point - -Gage is used for water administration or is important for water administration within a water <br />district. <br />0 points - -Ail other gages. <br />Goal 4-- Support Streamflow Gages for Determination of Trends in Flow <br />3 points - -Gage is an NSIP `Sentinel' gage (monitors streamflow in response to changes in climate, land <br />use, and water use in largely unregulated basins), or is one of up to 3 gages per major river basin, and no <br />more than one gage per tributary to a major river, that has < 5% of the gaged flow in annual diversions <br />into or out of the stream, and has > 25 years of record. <br />2 points- -Gage has > 50 years of record, regardless of diversions. <br />1 point - -Gage has > 25 years of record, regardless of diversions. <br />0 points - -All other gages. <br />Goal 5 -- Support Water - Quality Networks in Colorado <br />3 points - -Gage is an active site in a USGS National water - quality network or the USGS Idealized <br />Statewide Surface Water - Quality Network (see attached description of concepts for this network). <br />2 points - -Gage is an active site in a long -term water - quality network operated by USGS in Colorado or an <br />inactive site in the USGS Idealized Statewide Surface Water - Quality Network. <br />1 point —Gage is an active site in a long -term state or local water - quality network operated by others. <br />0 points--All other gages. <br />
