Data Assessment <br />3.2 Water Rights <br />Water rights are tabulated as required by law. Recent adjudications are systematically added to <br />the database, for a complete and robust compilation of decreed water rights in the basin. <br />Data Assessment: <br />Division 3 maintains the database of over 20,000 surface and ground water rights. The quality of <br />these data are considered good; the data were checked for some types of inconsistencies during <br />conversion to HydroBase, and any identified data issues will have been cleared up by project <br />commencement. Well locations are typically given as center of a specific quarter, and may not <br />plot precisely when data are exported to GIS coverages. These data are readily available from the <br />State Engineer's Office. <br />3.3 Wells <br />Publicly recorded well information in the San Luis Valley is available primarily from the State <br />Engineer's Office and the Colorado Oil and Gas Conservation Commission. These data vary <br />greatly in content and quality. Much of this information is administrative in nature. Well records <br />contain location, ownership, depth, and completion information. There can be other information, <br />as described below. <br />Data Assessment: <br />The data available from the State Engineer's Office is in the form of two distinct but overlapping <br />databases. The well water rights database contains the well owner information, location, proposed <br />use, and adjudication information about the well's water right. Most of the larger wells are <br />decreed and the public record may contain limited or anecdotal data on depth and production rate. <br />The well permit database also contains information about the well owner, location, and proposed <br />use. A well permit may also contain coarse geologic and hydrologic information in the form of <br />driller's descriptions of formations encountered, casing program, well depth, completion interval, <br />water level, and well yield. Not all permits contain this additional information and the water <br />rights are not necessarily cross referenced. Also, while the geologic and hydrologic information <br />associated with an individual permit may be acceptable, the consistency of these other data in the <br />permit records is poor. <br />The data available from the Colorado Oil and Gas Conservation Commission is primarily on oil <br />and gas test wells that were drilled during limited development efforts in the valley. The data <br />collected on these wells includes geophysical logs, drillstem tests, and geologic descriptions of <br />formations encountered. <br />The existing well data will be useful in studies using the RGDSS. These data are suited for <br />inclusion in the RGDSS relational database. However, it will be necessary to check these data as <br />they are incorporated in the database. Also, it will be necessary to resolve the present well permit <br />database with the present database of wells contained in the water rights database. This activity is <br />discussed further in Chapter 5.0. <br />a454/report/fmaUdata. doc 7/2&~OS 3 -2 <br />
