This addendum presents late-season field data collected in September 2003 that supplement the early-season data collected for this project in April 2003. The overriding objective of this water storage screening assessment is to identify water storage opportunities that could potentially meet multiple water needs in the Little Klickitat and Swale Creek subbasins of WRIA 30 – the two subbasins identified as priorities based on the Phase 2 Level 1 water quantity assessment for WRIA 30. The water storage screening assessment does not define water need priorities for those subbasins, or for the larger WRIA 30 watershed. Rather, it identifies a range of prospective storage opportunities in the two subbasins based on the subbasin physical characteristics as currently understood, irrespective of water needs. Because watershed hydrology, geology, topography, fish distribution and habitat, land ownership, and other factors may limit the number of feasible opportunities for water storage in any watershed, a screening-level identification of those opportunities is a useful first step in the process of water storage planning at the watershed scale. Priority water needs, as subsequently identified by the WRIA 30 Planning Unit, that could potentially be addressed through water storage, can then be matched up with feasible storage opportunities. As noted in the Phase 2 Level 1 Watershed Assessment, few hydrologic data exist for the Swale Creek and Little Klickitat subbasins. Therefore, a focus of this water storage screening assessment is field data collection to improve understanding of potential sources of excess water potentially available for storage, and the interaction between groundwater and stream flows in these subbasins. The potential benefits afforded by water storage in WRIA 30 can likely be realized predominantly during the dry summer months, therefore, dry season hydrologic conditions are of greatest interest. Consequently, data would optimally be collected both during the peak dry season or late- season September 2003), in addition to the early-season timeframe April 2003). Both early-season and late-season data collection efforts were included in the scope of work for the WRIA 30 water storage grant (Washington State Department of Ecology [Ecology] Grant G0300156). However, given the initial need to complete work under this grant within the 2001-2003 Biennium by June 30, 2003), the grant was partially funded to only include the early-season data collection (completed in April 2003). Those data were included as part of the June 2003 Multipurpose Water Storage Screening Assessment Report (Aspect Consulting 2003). The WRIA 30 Planning Unit subsequently applied for and was granted additional funding for Grant G0300156 under the budget for the 2003-2005 Biennium. This water storage screening assessment addendum was prepared by Aspect Consulting LLC, under subcontract to Watershed Professionals Network (WPN). This assessment was funded under Grant number G0300156 obtained by the WRIA 30 Planning Unit ---PAGE BREAK--- ASPECT CONSULTING 2 PROJECT NO. 020070-002-08 NOVEMBER 25, 2003 from the Washington State Department of Ecology (Ecology) under the Watershed Planning Act. Klickitat County is lead agency for the WRIA 30 Planning Unit. Following this introductory section, Section 2 describes the September 2003 field data collected, while Sections 3 and 4 present insights gained from the dry-season data relative to prospective water storage opportunities for the Swale Creek and Little Klickitat Subbasins respectively. This addendum is intended for use in conjunction with Aspect Consulting (2003), and the reader is referred to that report for additional detail regarding prospective water storage opportunities for each subbasin, as well as pertinent background information. 2 September 2003 Field Data Collection Field data were collected to gain preliminary understanding of the relative availability of excess water in different streams, and to improve understanding of groundwater-stream interactions, in the priority subbasins. In order to address seasonal variations, the preliminary screening assessment at the end of the wet season in April 2003 was followed by a dry season assessment in September 2003. The September field effort included observation of spring discharge locations as well as a quantification of spring and stream discharges as a basis for comparison with April observations. The same field data collection methods were used for the April and September observations and are presented in more detail in Aspect Consulting (2003). Summaries of the field data collection methods are presented below. Stream Gaging. Stream gaging was a primary focus of the September 2003 data collection, with the objective of understanding the relative magnitude of flows between different drainages, to document potential gaining or losing reaches of the creeks, and to compare these observations with the April 2003 data set. Stream gaging provides a single point-in-time measurement of stream discharge that supplements the scant available gaging data from these subbasins. A total of 22 stream discharge point measurements were collected from 10 streams spread across the Little Klickitat subbasin during the week of September 22-26, 2003 (Table Swale Creek was dry or stagnant upstream (east) of Harms Road, at river mile (RM) 12.2. of Harms Road, flows in Swale Canyon were not measured because flows were small; instead Swale Canyon flows were estimated visually, which is suitably accurate for the purposes of this assessment. Water Quality Sampling. In addition to the stream gaging, water samples were collected at selected surface water and spring locations for chemical analysis. The objective of collecting the water quality data is to provide an additional line of evidence (geochemical) to evaluate the relative contribution to instream flows from snowmelt or surface runoff versus groundwater discharge. This information is most useful by comparing the September 2003 data with data collected during April 2003 since the relative contribution of groundwater versus snowmelt should change seasonally, and might be reflected in water quality. September stream flows are expected to be derived solely from groundwater discharge (baseflow). ---PAGE BREAK--- ASPECT CONSULTING PROJECT NO. 020070-002-08 NOVEMBER 25, 2003 3 The April 2003 data collection was completed toward the end of the spring runoff period. In addition, 2003 had below average snowpack, and meltwater runoff from Simcoe Mountains snowpack peaked earlier than usual. Consequently, local instream flows in April 2003 were lower than typical for April. Regardless, the September data combined with the April data do provide useful information to evaluate potential water flows in a relative sense between various stream drainages within the subbasins and between the end of the wet and the peak of the dry seasons. The surface water samples were collected using the techniques described in Aspect Consulting (2003) and analyzed at North Creek Analytical in Bothell, Washington, for 9 parameters. The parameters analyzed were major cations (calcium, magnesium, sodium, potassium), major anions (bicarbonate, sulfate, chloride), dissolved iron and manganese, and bicarbonate alkalinity. Water hardness was calculated from the calcium and magnesium concentrations. Field parameters - temperature, pH, and electrical conductance - were also measured in the field at each location where stream gaging was performed, whether or not a water sample was also collected for full laboratory analysis. A total of 14 water samples were submitted for laboratory analysis, and water quality field parameters were measured at 32 locations, in September 2003 (Table The field data collection efforts are described for each subbasin in the next two sections. 2.1 Swale Creek Subbasin A dry season field reconnaissance of the Swale Creek subbasin was completed on September 22 and 23, 2003. The first day included a reconnaissance of the upper and central subbasin – from the headwater tributaries east of Highway 97, through the Centerville valley, down to Harms Road just west of Warwick. The second day involved a reconnaissance of Swale Canyon, from Harms Road to the creek mouth at Wahkiacus. The reconnaissance effort included visual estimates of stream flows in tributaries, observation of channel conditions, water quality parameter measurements (pH, temperature, and conductance), and observation and sampling of spring discharge. Field observations and measurements are recorded on Figure 1 (oversize plate). Several small tributaries were observed entering Swale Canyon, with individual flows estimated visually from dry to perhaps 0.5 cfs. On Figure 1, the discharge measurement locations are shown as triangles, and the visual qualitative flow estimates are shown as circles. For the qualitative flow estimates, the term “minor flow” indicates flow that likely fell in the range of 0.1 to 0.5 cfs, and the term “trickle” was used for flows likely less than 0.1 cfs. In addition, water quality samples were collected from Swale Creek at one of the three April sampling locations (Swale-1) which had sufficient flow. Water quality samples were also collected from two spring locations that had sufficient discrete flow to allow sample collection. Water sample Spr-1-Swale was collected from a small spring emanating from the Wanapum Basalt on the north side of Swale Creek (at RM 9.4). This spring was the first one observed west of Harms Road that had sufficient flow for water sample collection and was also sampled during the April 2003 field season. Visual reconnaissance above the spring in April 2003 confirmed it was not fed by higher elevation surface runoff; the fact that it continues to flow in September confirms this. ---PAGE BREAK--- ASPECT CONSULTING 4 PROJECT NO. 020070-002-08 NOVEMBER 25, 2003 Further down Swale Canyon (at RM water sample Spr-3-Swale was collected from a small spring emanating from the Grande Ronde Basalt on the east side of the canyon. These spring sample locations are shown on Figure 1. The spring at RM 3.4 sampled in April 2003 (Spr-2-Swale) was not observed in September 2003. The water quality data – laboratory and field parameter – collected from the Swale Creek subbasin in April and September 2003 are presented in Table 2. 2.2 Little Klickitat Subbasin A dry season field reconnaissance of the Little Klickitat subbasin was conducted September 22-26, 2003. During this time, we collected stream/spring discharge and water quality field parameter measurements at 22 locations, and 11 water quality samples for full laboratory analysis (2 samples of spring discharge and 9 samples from streams). Stream gaging was performed at the following locations: • Two locations on Blockhouse Creek (RM 3.9 and 4.3); • Two locations on Bloodgood Creek (at RM 0.4, and at Bloodgood Springs where the spring discharge enters the culvert under Pine Forest Road); • Four locations on Bowman Creek (RM 0.5, 3.6, 12.8, and 16.8); • Two locations on Butler Creek (RM 0.1 and 3.7); • One location at RM 2.1 on Devil’s Canyon, a tributary joining Mill Creek at RM 11; • One location on a tributary (Brimstone Creek) joining Dry Creek at RM 2.0; • Four locations on Mill Creek (RM 4.0, 8.4, 12.7, and 14.5); • Two locations on the West Prong Little Klickitat River (RM 0.06 and 4.7); • One location on Spring Creek (RM 0.7); and • Three locations on Little Klickitat River (RM 0.15, 9.0, 17.5). The data collection locations, with discharge and field parameter measurements, are depicted on Figure 2. The stream gaging data and water quality data are presented in Tables 1 and 2, respectively. In addition to sampling stream surface water at 9 locations (see Table water quality samples were also collected from Presher Spring (T6N R15E section 34) and Bloodgood Spring (T4N R16E section both of which discharge from the Simcoe Volcanics. The water sample from Bloodgood Spring was collected as a grab sample from the overflow from the two vaults within the City of Goldendale’s spring collection system. The measured discharge from Bloodgood Spring was 6.4 cfs at the point where the discharge enters a culvert under Pine Forest Road. The Presher Spring discharge was estimated at 50 gpm (0.1 cfs) at the time of the September 2003 observation. No discharge was observed from Shelton Spring (T6N R14E section 35), which emanates from the Wanapum Basalt. ---PAGE BREAK--- ASPECT CONSULTING PROJECT NO. 020070-002-08 NOVEMBER 25, 2003 5 2.3 Analytical Data Quality Assurance Review A quality assurance review of the laboratory’s analytical data packages was performed to ensure that the data were of suitable quality for their intended use. The laboratory certificates of analysis are included in Appendix A. The quality assurance review included evaluation of sample custody, holding times, method blank analysis, laboratory control sample (blank spike) and matrix spike/matrix spike duplicate recoveries and precision, and post-digestion spike recoveries. The results of the quality assurance review are as follow: 1. Sample custody and holding times were acceptable. 2. No method blank contamination was detected. 3. Laboratory control sample (LCS) recoveries were within control limits. 4. Matrix spike (MS), matrix spike duplicate (MSD), and post-digestion spike recoveries were within control limits. 5. The relative percent differences (RPDs) for MS/MSD sample pairs were within control limits. Based on the quality assurance review, the analytical data are determined to be of acceptable quality for their intended use. No data were qualified based on the QA reviews. ---PAGE BREAK--- ASPECT CONSULTING 6 PROJECT NO. 020070-002-08 NOVEMBER 25, 2003 3 Conclusions Regarding Water Storage Opportunities in Swale Creek This section presents updated conclusions regarding the hydrologic conceptual model and prospective options for water storage for the Swale Creek subbasin based on the observations from the September 2003 field data collection. • Above Swale Canyon, stagnant water was present in several locations along Swale Creek, but no flow was observed. In particular, stagnant pools were observed at Hoctor Road, Highway 97, and Uecker Road. These pools were isolated, with dry reaches both upstream and • As Swale Creek entered Swale Canyon, pooled water was observed more frequently. Large pools were present immediately west of Harms Road and again about 1.5 miles As Swale Creek neared the bend to the north, another long pool of water was observed. Flow in Swale Canyon began at the confluence with Stacker Canyon (approximately at the bend to the North at RM 9.2) which provided approximately 0.5 cfs to Swale Creek. of this point, Swale Creek would interchange back and forth from flowing, to pooled, to dry (on the surface) multiple times. Flow was typically observed in bedrock constrained reaches of Swale Creek and was not present in alluvial reaches. As a rough estimate, 40 percent of Swale Canyon had flowing water, 20 percent had pooled water, and the remainder was dry. • The springs observed emanating from the east wall of the Canyon (Spr-1-Swale and Spr-3-Swale) did not contribute much flow to the creek, consistent with April observations. Discharge at the end of Swale Canyon was approximately equal to the input from Stacker Canyon, further indicating limited input from groundwater discharge. • The groundwater level in a shallow well completed in the alluvial aquifer east of Warwick and located near Swale Creek (adjacent to Matson Road) was 7.3 feet below ground surface (bgs). This is lower than observed in April (2 feet bgs), but was not as low as anticipated. • Juvenile fish were observed in most pools located in Swale Canyon. In particular, a large number of juveniles were present in a stagnant pool under a railroad bridge trestle at RM 4.6. • Water temperatures in Swale Canyon ranged from 13 to 19.5º C and generally increased as the water traveled The stagnant pool above Stacker Canyon was warmer (17º C) than the water flowing from Stacker Canyon (15º The measured increase in temperature down the canyon also reflects the difference in time of day of the measurement; the warmest temperatures were measured later in the day. • Water quality in Swale Creek and the spring discharging from the Grande Ronde Basalt (Spr-3-Swale) continued to have the highest conductance, hardness, and ---PAGE BREAK--- ASPECT CONSULTING PROJECT NO. 020070-002-08 NOVEMBER 25, 2003 7 dissolved cation and anion concentrations observed. The September 2003 water hardness at the mouth of Swale Creek (Swale-1) was more than double that measured in April 2003. The spring discharging from the Wanapum Basalt (Spr-1-Swale), by contrast, had water quality concentrations similar to those observed in the Little Klickitat subbasin. The September 2003 data collection provides additional information to document dry- season hydrology. In general, the observations do not change the previously presented conclusions regarding the viability of enhanced recharge, aquifer storage and recovery, on-channel impoundment, or off-channel impoundment water storage projects. The apparent presence of some, albeit small, year round flow through Swale Canyon and the observation of juvenile fish in multiple locations there indicates that there may be a habitat and fisheries benefit to providing additional water through the canyon during the dry season. This goal should be considered when evaluating future multipurpose storage projects in the Swale Creek subbasin. ---PAGE BREAK--- ASPECT CONSULTING 8 PROJECT NO. 020070-002-08 NOVEMBER 25, 2003 4 Conclusions Regarding Water Storage Opportunities in Little Klickitat Subbasin This section presents updated conclusions regarding the hydrologic conceptual model and prospective options for water storage for the Little Klickitat subbasin based on the observations from the September 2003 field data collection. • Flow in the Little Klickitat River near the confluence with the Klickitat River (Little Klick-3) was 30.6 cfs. Most of this flow originated in the western portion of the subbasin. The highest flows were observed in Spring, Mill and Bowman Creeks, and Bloodgood Springs. These four sources account for 83 percent (25 cfs) of the flow in the Little Klickitat, but only 45 percent of the total subbasin area. These four creeks are located primarily in the Simcoe Volcanics, and are presumably sustained throughout the dry season by groundwater discharge. • Comparing flow measurements from the Little Klickitat River with the sum of measured flows in the individual tributaries yields some interesting results. For example, the total flow from West Prong and Butler Creeks was 2.1 cfs and the flow in the Little Klickitat River approximately ¾ mile (at Little Klick-1) was 1.4 cfs. The difference indicates that this is a losing reach of the Little Klickitat with some flow infiltrating into the alluvium present in that area. Gaging error may also contribute to the observed difference. • Further the observed flow at Little Klick-2 was 6.6 cfs which is less than the sum of Little Klick-1, Bloodgood Creek, and Cozy Nook Creek flows which add to 8 cfs. Again the difference indicates that the Little Klickitat River continues to lose water to the extensive reach of alluvium between the Little Klic k-1 and Little Klick-2 stations (near Goldendale). • Finally, the observed flow at Little Klick-3 (RM 0.3) was 30.6 cfs and the total flow from the tributaries and Little Klick-2 was 29.1 cfs. This close agreement indicates that this lower reach of the Little Klickitat (incised into Wanapum Basalt) is neither losing nor strongly gaining. • Canyon Creek and the East Prong of the Little Klickitat were dry at all locations observed. Canyon Creek may begin flowing (from groundwater discharge) as it enters its canyon towards the confluence with Bowman Creek. The increase in stream flow between Bowman Creek stations 1 and 2 suggest that this reach of Canyon Creek was flowing. • Idlewild and Dry Creek were dry at their confluences with the East Prong of the Little Klickitat, but were observed flowing 0.1 cfs) in upstream reaches. Dry Creek's flow came from Brimstone Creek. Flow observed in the upper reaches infiltrated upon reaching the alluvial reaches near the confluence with the East Prong. ---PAGE BREAK--- ASPECT CONSULTING PROJECT NO. 020070-002-08 NOVEMBER 25, 2003 9 • Water quality in the Little Klickitat subbasin was generally consistent throughout the subbasin and between spring and surface water samples. The data were consistent with April 2003 data. As with the Swale Creek subbasin, in general, the observations from the September 2003 data collection provide additional information that may be useful in the design or evaluation of potential storage projects, but do not substantively change the previously presented general conclusions regarding the viability of enhanced recharge, aquifer storage and recovery, on-channel impoundment, or off-channel impoundment water storage projects. The most significant observation related to water storage in this subbasin is the degree of control that the alluvial reaches have on the presence or absence of surface flow in the late summer/early fall. Each of the creeks that were observed to be dry or losing water had significant alluvial reaches. Figure 6 in Aspect Consulting (2003) is a geologic map showing the extent of alluvium in this subbasin. When planning a water storage project upstream of an alluvial reach, care should be taken to understand the extent and properties of the alluvium and the amount of water that may infiltrate into it if released back into the stream. Alternatively, the alluvium also may hold opportunities for enhanced recharge as outlined in Aspect Consulting (2003).
