D. \,ATER RESOURCES

\,ater resources in the study area are classified as tributary, Tributary water
is sa i d to be in" hydraul i c" connecti on wi th surface waters. Thus, a well extrac-
ting water from a relatively shallow table affects the level of adjacent surface
water.

Parkville Water District is a part of the Arkansas River Basin which is adminis-
tered by the State Engineer and the Division II Water Commissioner. The Arkansas
River Basin is described as one of the tightest watersheds in the State. Generally,
water rights have been over appropriated and daily "calls" by senior water right holders
occur. Additionally, water yield from registered wells in the Leadville area general-
ly does not exceed 15 gallons per minute, a low yield,

Extraction of water resources from the study area has the potential to incrementally
damage not only senior users below the Parkville Water District diversion points,
but also the ilT1l1lediate watershed area above the diversion points,

VI. W. Wheeler and Associates, Inc" engineering consultants to the Parkvi1le Water
District in a letter dated October 17, 1979, summarized their concerns regarding de-
velopment in the District.

-Diversion of Water: "First, any diversion of water that results in a re-
duction of flow at the District's diversion points will cause an injury to
the District. Therefore, any wells or surface diversions that deplete the
floVl of water will cause such an injury."

-Pollution: "Development could result in bacteriological and viral contam-
ination and increased tUbidity loads that would degrade the quality of the
water supply. The extent of pollution would be dependent on the amount and
type of development, the method of sewage treatment, the proximity to the
stream and other factors. However, some pollution would result merely from
the increased presence of people and the associated need for roads, the cre-
ation of dust and erosion and the presence of pets and livestock."

Reference may be made to Appendix A concerning annual water requirements of the
Parkvi11e Water District.

A high probability exists that material injury to the vested water rights of others
will result if additional water resources are extracted. Nevertheless, the ultimate
pronouncement of this fact rests in the hands of the court system,

1. THE PROCESS:

Generally, if land was subdivided prior to June 1, 1972, household well permits will
be granted. Water from a household well may not be used for the watering of lawns.
trees, etc., and can be used for in-house use only. While a permit is required, de-
nial of a household well permit may be obtained only after the state engineer deter-
l11i nes tha t the well wou1 d "materi ally injure the vested ri ghts of others or any other
existing \o/ell." (148-21-45(3)(b)(ii),)

Concerning domestic wells, the law states that there shall be a presumption that
"...there Ivi11 not be material injury to the vested water rights of others." (148-
