Bainbridge Island, WA 98110 [PHONE REDACTED] www.aspectconsulting.com ---PAGE BREAK--- MEMORANDUM June 29, 2011 Project No.: 070024-013 Page 2 Well Monitoring Network The water level monitoring network was established in order to: provide spatial coverage of the basin, and provide a representative number of wells completed in the various aquifers to allow for differentiation of water levels within the respective hydrostratigraphic units. Within Little Klickitat subbasin, the thin veneer of unconsolidated alluvium occurring locally is not considered to be an important water supply aquifer due to the limited number of wells completed within the respective unit. Therefore, for the purposes of this assessment, the alluvium aquifer has not currently been included in the water level monitoring network. The expansion of the Little Klickitat subbasin monitoring network added 5 new wells, bringing the total number of wells to 11. Figure 2 depicts the locations of the wells included in the water level monitoring network. Table 1 summarizes the well information, and Table 2 presents the water level measurements to date. Well Survey Wells included in the original monitoring network were surveyed y, z) by a licensed surveyor with Klickitat County Public Works, as described in Aspect Consulting (2007). Wells included in the expanded monitoring network were surveyed by Klickitat County Public Works in December 2010. Table 1 includes survey data for the wells included in the monitoring network. Water Level Measurements Depth-to-water measurements were conducted in all monitoring network wells using either an electric water level indicator (tape) or a sonic water level indicator (sounder)1. The former provides greater precision, but has the significant disadvantage of potentially becoming permanently caught on wiring or other appurtenances within the well casing. The latter has less precision but is much faster to use, and more importantly, does not have the risk of becoming caught in the well. The Quality Assurance Project Plan (QAPP) (Aspect, 2010) for this project provides a quality control (QC) evaluation between the tape and sonic sounder based on measurements collected since 2007. The evaluation documents reliability of the sonic sounder for measuring depths-to-water less than about 250 feet (Aspect, 2010). All depth-to-water measurements were made in accordance with the project-specific QAPP (Aspect, 2010), and relative to the top of well casing or other defined measuring point at the wellhead. The selected measuring point for each well was marked in magic marker, if possible, and was documented in the field form so that it can be reproduced during subsequent measurement rounds. Other pertinent information regarding the well or the measuring of water levels in it were also recorded in the field notes. If a downhole water level indicator was used for the depth-to-water measurement, the lower couple of feet of tape was rinsed and wiped with a clean paper towel. Any rust or other visible material on the water level indicator after a measurement was also wiped off using a clean paper towel prior to the next measurement. 1 Global Water WL600 or equivalent instrument. ---PAGE BREAK--- MEMORANDUM June 29, 2011 Project No.: 070024-013 Page 3 A table of static water level measurements from either the respective well logs or previous monitoring event was carried in the field. Measurements that varied greatly from past measurements in a given well (accounting for differences between spring and fall) were repeated for confirmation. Description of Well Monitoring Network Aquifers A generalized geologic history of the Little Klickitat subbasin is provided in the WRIA 30 Level 1 watershed assessment (WPN and Aspect, 2004). Water-bearing hydrostratigraphic units within the study area include (from youngest to oldest): • Simcoe Mountains volcanic deposits; • Wanapum basalt (Priest Rapids, Roza, and Frenchman Springs members); and • Grande Ronde basalt. The Wanapum and Grande Ronde basalts are formations within the Columbia River Basalt Group (CRBG). Groundwater in the CRBG primarily occurs in the top of the individual flows (“flow top”), which became vesicular (porous) as gas bubbles escaped the flows during cooling, and/or at the flow bottoms (sometimes referred to as “pillows”). Flow tops and bottoms—collectively referred to as interflow zones—are usually porous and permeable, and therefore transmit water more readily than the intervening massive portions of the basalt flow interior, which generally constitute flow barriers, except where fractured. For wells completed in the interflow zones between the various basalt units, water levels are considered to be representative of the underlying basalt aquifer. A permeable flow top is normally present for each flow, while permeable flow bottoms range from relatively thick units to completely absent. The lateral continuity of water- bearing interflow zones is highly variable. Within the Goldendale area of Little Klickitat subbasin, a majority of the wells completed in the CRBG are completed in the interflow zones of the Wanapum basalt aquifer (Priest Rapids, Roza, and Frenchman Springs members). The water level monitoring network currently does not include any wells completed solely in the Grande Ronde basalt aquifer. In addition, terrestrial sediments can be deposited between the underlying flow top and overlying flow bottom during time periods between basalt flows. These sediments are collectively considered part of the Ellensburg Formation and can be either relatively permeable or impermeable; depending on composition, thickness, and lateral extent. Both the lateral continuity and thickness of the water- bearing interflow zones are highly variable. Simcoe Mountains Volcanic Aquifer The Simcoe Mountains volcanic deposits are generally composed of basalt flows and volcanic cinder erupted from a series of low shield volcanoes and subsidiary cinder cones within the local area. Within Little Klickitat subbasin, particularly the Goldendale area, the Simcoe Mountains volcanic deposits are a prolific aquifer. ---PAGE BREAK--- MEMORANDUM June 29, 2011 Project No.: 070024-013 Page 4 Of the 11 wells included in the Little Klickitat subbasin water level monitoring network, there are currently 2 wells completed in the Simcoe Mountains volcanic aquifer (T05/R14-R1 and T05/R15- 19L1). Figure 2 provides the location of these wells. Additional wells completed in the Simcoe Mountains volcanic aquifer may need to be added in order to improve spatial coverage of groundwater level monitoring in this aquifer. One well which could be included in a further expansion of the Little Klickitat subbasin water level monitoring network is the City of Goldendale’s Chlorination Station well, located in Section 21 of T05/R16. Wanapum Basalt Aquifer Of the 11 wells included in the Little Klickitat subbasin water level monitoring network, there are currently 9 wells completed in the Wanapum basalt aquifer. Figure 2 provides the location of these wells. Summary of Groundwater Level Measurements Table 1 provides a summary of the groundwater level measurements from the Little Klickitat subbasin water level monitoring network to date. Evaluation of long-term trends in groundwater levels provides insight regarding aquifer response to precipitation patterns and sustainability of the existing level of groundwater withdrawal. Long-Term Groundwater Level Trends Long-term groundwater level trends can be evaluated for the 4 wells included in the water level monitoring network as part of the Swale Creek and Little Klickitat subbasin water availability reports (Aspect, 2007). Groundwater level measurements for these wells have been made on a semi-annual basis (pre-irrigation and post-irrigation) since June 2007. In addition, semi-annual water level measurements for the City of Goldendale’s Third Street (T04/R16-16Q1) and Dingmon (T04/R16-28A1) wells have been collected since November 2007. Figure 3 provides long-term groundwater level hydrographs for these wells. Solid lines indicate wells completed in the Wanapum basalt aquifer, while dashed lines indicate wells completed in the Simcoe Mountains volcanic aquifer. Since there are currently only three rounds of water level measurements (May 2010, November/December 2010, and May 2011) for the expanded monitoring network wells, long-term groundwater level trends will not be evaluated for these wells at this time. Trends for wells monitored since 2007 are outlined below. Wanapum Basalt Aquifer Based on the hydrographs on Figure 3, none of the Wanapum basalt aquifer wells monitored showed any significant long-term decrease in groundwater levels during the period of monitoring (June 2007 to May 2011). One well (T04/R15-26H1) had an overall increase in groundwater levels of about 10 feet since June 2007. Seasonal changes of up to 10 feet were observed in several of the Wanapum basalt aquifer wells (T04/R15-26H1, T04/R16-16Q1, and T04/R16-28A1). For these wells, the lowest groundwater levels were consistently observed during the post-irrigation measurements (November) and the highest groundwater levels were consistently observed during pre-irrigation measurements (April - June). The seasonal declines in the water levels are primarily in response to pumping; however, the water levels have consistently recovered on an annual basis over the period of record. Therefore, the available data indicate that the Wanapum basalt aquifer ---PAGE BREAK--- MEMORANDUM June 29, 2011 Project No.: 070024-013 Page 5 storage is not being depleted and that current and recent historical pumpage in Little Klickitat subbasin is sustainable on a regional scale. In addition, the lack of depletion observed in the Wanapum basalt aquifer storage has occurred during a generally below-average period of precipitation. Figure 4 presents both the annual precipitation and the mean annual precipitation (upper portion of figure) and the cumulative departure from the mean annual precipitation (lower portion of figure) in Goldendale (NOAA Station #453222) and at Satus Pass (NOAA Station #457342) for the period of record (1931 - 2010)2. Note that individual months with more than 5 days of missing data were not used for or annual precipitation statistics (so those years are not displayed on Figure With the exception of 1995-1998 and 2010 (based on Goldendale data3) and 2006 (based on Satus Pass data), annual precipitation has been at or below the mean annual precipitation since 1984. However, the below-average precipitation has not appeared to affect groundwater levels in the Wanapum basalt aquifer, indicating that the aquifer is not overly sensitive to long-term precipitation trends and may be able to handle additional withdrawals. Recommendations It is recommended that the expanded water level monitoring network continue to be monitored on at least a semi-annual basis (pre-irrigation and post-irrigation measurements), subject to availability of funding. Although an effort was made to expand the Little Klickitat subbasin water level monitoring network in 2010, only 5 additional wells were added based on permissions received from well owners. Therefore, it is recommended that, when possible, the Little Klickitat subbasin water level monitoring network be expanded to include additional wells, especially wells completed in the Simcoe Mountains volcanics aquifer in the northern portion of the subbasin.
