o Colorado Municipal League and Colorado Counties Inc.;directories.

o State HydrOBase water rights ownersh,i.p database.

o CDPHE Water Quality Control Division's Source Water Protection contact list.

o The three water conservation distticts ,(Colorado River, Rio Grande, and
Southwestern) and all Water Conservancy Districts in Colorado (identified in Table
4-1).

o Other state, federal, and local water mimagement entities, Colorado Task Force, and
other ad hoc advisory councils id~ti#ed by the CWCB or entities c~ntacted while
developing the target list. ' ! , '

o Any other outside resource (e.g., datalilase vendors or other research entities).

CWCB ,and other relevant parties will work with us in, order to evaluate the breadth and
completeness of the coverages in the initial database. The database will then be "cleansed" or
crosschecked wij:h reference materials and verification methods to ensure the greatest number
of possible contacts (respondent IllUl]Ji!s) with the greatest number of contact points (telephone
numbers, e-malls, mailing addresses, fax numbers). All data will undergo standard quality
assurance and quality control checks as well.

once the database has been adequately populated, and the user prOfiles have been established
to assure that the right information is captured, the database will be queried and the results .
evaluated to identify survey target lists 'are both comprehensive, and at the ~ame time,
manageable. We know, for example, that it ,would not be feasible to contact every water right
owner and well permit owner in the State. The !State Erigineer's Office water rights tabulation
for Division 1 alone (the South Platte River basm) includes over 34,000 water rights, with more
than 25,000 of those rights being wells. Many!of the rights are supplemental adjudications,
transfers, and augmentation rights related to 'individual original water rights and owners.
Contacting all ow'i.'fers associated with these rights (including all the other water divisions in the
State) is not within the scope of this project. H6wever, we propose filtering the list to a subset
of major water rights and their respectiv~ owners by limiting the list to those rights of a
minimum d~creed amoUnt. For instance, a breakdown by size of the wells with decreed water
rights in Division 1 is indicated in Table 4-2. ' ,
