Major aquifers, well yields, number of index wells and date of last water-level sweep are shown in Table 6.5-3. Figure 6.5-6 shows water-level change between 1990-1991 and 2003-2004. Figure 6.5-7 contains the hydrograph for the selected well shown on Figure 6.5-6. A description of aquifer data sources and methods as well as well data sources and methods, including water-level changes and well yields are found in Volume 1, Appendix A.
- Refer to Table 6.5-3 and Figure 6.5-6.
The major aquifer in the basin is the recent stream alluvium.
Almost all of the basin geology consists of consolidated crystalline and sedimentary rock.
Data on natural recharge, groundwater in storage and groundwater flow direction is not available for this basin.
- Refer to Table 6.5-3
- One source of well yield information, based on 17 reported wells, indicates that the median well yield in this basin is five gallons per minute.
- Refer to Figure 6.5-6. Water levels are shown for wells measured in 2003-2004.
- There are no index wells in this basin.
- Water level information is available for one well in this basin, with a depth to water of 960 feet. A hydrograph for this well is shown in Figure 6.5-7.
