• 2.oa.~ <br />bearing areas within the water bearing zones and also areas where the data <br />points show these zones to be dry. This interpretation indicates that the <br />recharge area into the perched water zones is near the outcrop of the <br />sandstone subcropping underneath the local drainages. The general <br />groundwater flow in the Mesaverde perched water zones is toward north, <br />following the basin structure. <br />The water probably originates in the colluvium or Colluvial water recharges <br />of the shallower Mesaverde Formation lithologies. The alternating lenticular <br />channel sandstone and enclosing overbank claystone lithologies within the <br />upper Mesaverde Formation has the potential to create perched water table <br />conditions within the permit area. These conditions, which are a function of <br />the deltaic fluvial depositional environment, are characterized by confined, <br />saturated horizons of localized lateral and vertical extent within low porosity, <br />unsaturated intervals. These perched, confined horizons may exhibit artisan <br />conditions; however, flowing conditions were not observed within the permit <br />area. <br />• The erratic location of these perched groundwater occurrences, low <br />transmissivity and permeability, and the absence of development and <br />exploitation diminishes the possibility of being used as a groundwater <br />resource in the foreseeable future. <br />Colluvial Near Surface Storage <br />Within the permit boundary area, there are several Colluvial deposits. These <br />deposits are contained in the mixtures of clay, sand, and silt with some large <br />rock fragments. These strata were formed by slow downslope movements <br />of near surface materials, locally reworked by fluvial processes. The lateral <br />extent of these strata is shown on Surficial Geology Map 05, where the <br />quaternary deposits have a symbol "Q,5' at the head of Freeman, Sheep <br />Corral and Dove gulches, "Q~~Z' in Stephen's Draw, and "Q1sz' in C-Gulch. <br />The most significant of these deposits are the "Q,;' deposits at the head of <br />Freeman and Dove gulches. <br />These unconsolidated quaternary deposits are the primary sources of <br />springs and seeps within the Permit Area. Typically, discharge is small (less <br />• than 5 gpm) and conductivity low to moderate (100-500 umhos/cm -refer to <br />PR-03 2.04 - 28 - 5/99 <br />
