<br />. <br /> <br />. <br /> <br />. <br /> <br />12. <br /> <br />Southern High Plains Ground Water Management District - Designated Groundwater Basin Studv <br />Authorization: Long Bill Grant Amount: $65,000 <br />Water Source: Southern High Plains Groundwater Basin Project Type: Hydrogeology Study <br />Location: SE Baca, Prowers, & Las Animas Counties Project Manager: Mike SerletlSEO staff <br /> <br />This project was the study of the Southern High Plains Groundwater Basin located south of the <br />Arkansas River in Baca, Prowers and Las Animas Counties. The study evaluated the relationships between <br />groundwater pumping and the resulting groundwater levels in the aquifer. The report also tried to estimate <br />the economically recoverable groundwater resources in the aquifer. <br /> <br />The Phase I study made several recommendations: <br /> <br />1. The Southern High Plains District (District) should require metering of all groundwater usage <br />in the District. <br />2. The District should require geophysical logging of any new high capacity irrigation wells <br />drilled in the District. <br />3. The District should request the Colorado Ground Water Commission issue a moratorium on <br />all new well pennits and pennits for additional acreage from existing wells in the District. <br />4. The District should enter into an information sharing relationship with the adjacent Kansas <br />groundwater management district. <br />5. New monitoring wells are needed to more adequately study the aquifer. <br /> <br />The Phase II study made several other recommen,dations: <br /> <br />1. Require flow meters be installed on all wells. <br />2~ Limit irrigated acreage expansion. <br />3. Coordinate with the Colorado Grouud Water Commission to reduce the maximum annual <br />allowable amount of irrigation well water to 2.5 ac.ft./ac. <br />4. Establish well spacing criteria based upon specific source aquifer parameters. <br />5. The High Plains aquifer should be closed to any new large capaCity wells. <br />6. Establish large capacity well completion criteria. <br />7. Create a large capacity well plugging and monitoring program. <br />8. Coordinate with the State Engineer to install new recording transducers and conduct pumping <br />tests. <br /> <br />McLaughlin Water Engineers of Denver completed the study in January 2002. <br /> <br />13 - 16 Stream gaging projects are detailed above with Item No. 43. <br /> <br />17. <br /> <br />Instream Flow Decision Support System aSFDSS) <br />Authorization: Long Bill <br />Water Source: Statewide <br />Location: Statewide <br /> <br />Grant Amount: $25,000 <br />Project Type: ISFDSS <br />Project Manager: Greg Espegren <br /> <br />On November 27,2001, the Colorado Water Conservation Board (CWCB) entered into a contract <br />with Bishop Brogden Associates, Inc. to evaluate opportunities for developing an Instream Flow DeCision <br />Support System (ISFDSS) component of the Colorado Decision Support System (CDSS). Ross Bethel is <br />Bishop Brogden's primary contact on the current ISFDSS contract. At this time, Ross and the CWCB <br />staff have met on several occasions to discuss the staffs ISFDSS needs. Based on our discussions and <br />evaluations, Ross has used a commerCial software application called ArcView 8.2 to develop a conceptual <br />prototype of the ISFDSS component ofCDSS. The prototype demonstrates some of the data analysis and <br /> <br />Page 29 001 <br />
