1.0 INTRODUCTION

The Bureau of Indian Affairs (BIA), in cooperation with the Colorado River Indian Tribes (CRIT), is planning to rehabilitate or replace the first three check structures on the Main Canal of the Colorado River Irrigation Project (CRIP) within the boundaries of the Colorado River Indian Reservation (CRIR) near Parker, Arizona.

The check structures include:

Main Canal Check 185 (MC 185), Main Canal Check 270 (MC 270), and

Main Canal Check 420 (MC 420).

CRIP uses a naming convention based on canal stationing, increasing downstream from the start of the Main Canal at Headgate Rock Dam on the Colorado River.

DOWL completed a groundwater monitoring investigation for the three CRIP Main Canal check structures to inform the design and construction activities. This report presents a brief summary of the methods and results of the groundwater investigation.

Elevations reported in this document are in reference to the North American Vertical Datum of 1988 (NAVD 88). Groundwater elevations are considered approximate and are based on best available information at the time the data were collected; actual subsurface conditions may vary.

2.0 INVESTIGATION

DOWL performed geotechnical activities on August 22nd and 23rd, 2022. Activities included advancing six geotechnical borings to document subsurface conditions1 and developing five of the borings as groundwater monitoring wells. DOWL subcontracted geotechnical drilling and well development to Enviro-Drill, Inc. The five monitoring wells included monitoring well MW 185-1 in the vicinity of structure MC 185, well MW 270-1 near structure MC 270, and three monitoring wells MW 420-1, MW 420-2, and MW 420-4 near structure MC 420. Appendix A includes maps of the project area, showing the locations of the check structures and monitoring wells. DOWL considered three monitoring wells at MC 420 to be sufficient and did not install a monitoring well in boring 420-3.

Each monitoring well consists of approximately 33 feet of 2-inch diameter PVC pipe. DOWL installed pressure transducers (Solinst 3001 LeveLogger 5 water level dataloggers) in each monitoring well and set them to measure absolute pressure (i.e., water pressure plus atmospheric pressure) and temperature at eight-hour intervals. DOWL also installed a barometric pressure datalogger (Solinst 3001 BaroLogger 5) in MW 420-2 to monitor and log atmospheric pressure.

CRIP decommissioned and formally abandoned MW 420-4 on January 18, 2023, following coordination between DOWL and the BIA. Decommissioning included removing the concrete base and cutting the standpipe to 6 in below the canal road to avoid conflicts with future road maintenance. The PVC monitoring well pipe was plugged with bentonite chips and capped with sack-mix concrete. This report does not document groundwater elevation results for MW 420-4.

3.0 RESULTS

The groundwater study period spanned from August 25th, 2022, to October 5th, 2023. DOWL periodically visited the site to download pressure transducer data during the study period. The logged pressure

readings represent the pressure head of water above the sensor plus atmospheric pressure. During the January 2023 site visit, DOWL estimated sensor elevations for each monitoring well by tying the water pressure head above the sensor (i.e., absolute pressure minus atmospheric pressure) to the groundwater elevation measured through survey and measure-down methods. Table 1 summarizes the sensor elevations and groundwater elevations observed during the study period, corrected for atmospheric pressure. Appendix B tabulates the collected temperature and pressure data.

3.1 ATMOSPHERIC PRESSURE ASSUMPTIONS

The Solinst pressure transducers used in this study collect absolute pressure (i.e., pressure relative to a vacuum) in the monitoring well. These pressure measurements are the sum of atmospheric pressure and pressure head (i.e., depth of water above the sensor). The following equation shows the basic process for computing the groundwater elevation given the sensor elevation, pressure transducer reading, and atmospheric pressure.

𝐺𝑟𝑜𝑢𝑛𝑑𝑤𝑎𝑡𝑒𝑟 𝐸𝑙. (𝑓𝑡) = 𝑆𝑒𝑛𝑠𝑜𝑟 𝐸𝑙. (𝑓𝑡) + 𝐴𝑏𝑠𝑜𝑙𝑢𝑡𝑒 𝑃𝑟𝑒𝑠𝑠𝑢𝑟𝑒 (𝑓𝑡) − 𝐴𝑡𝑚𝑜𝑠𝑝ℎ𝑒𝑟𝑖𝑐 𝑃𝑟𝑒𝑠𝑠𝑢𝑟𝑒 (𝑓𝑡)

The Solinst BaroLogger installed at 420-2 measures atmospheric pressure. DOWL downloaded initial data from this sensor during the October 2022 site visit, however, the BaroLogger was stolen from the site between October 2022 and the January 2023 site visit. Consequently, barometric pressure data recorded at the site do not encompass the entire monitoring period and cannot be used in the pressure correction to estimate groundwater elevation.

Two nearby National Weather Service (NWS) climactic stations, Havasu City Airport (KHII)2 and Blythe Airport (KBLH)3 record barometric pressure. Appendix A depicts the location of the NWS stations relative to the Main Canal Check Structures. Table 2 compares barometric pressure records at these stations to the available data from the MW 420-2 BaroLogger. Note that this table summarizes all hourly data for each month for the NWS stations, while the BaroLogger data is only available for the period August 26 to October 26. The Blythe Airport August through September average, minimum, and maximum barometric pressures are very similar (i.e., within 0.1 ft) to the BaroLogger values. Based on the general agreement between the Blythe Airport station and the BaroLogger, DOWL considers barometric data from the Blythe Airport station to be representative of conditions at the monitoring wells for the purposes of this analysis.

DOWL corrected each pressure transducer measurement for atmospheric pressure using hourly barometric data from the Blythe Airport Gage.

3.2 MC 185

Figure 1 depicts the MW 185-1 groundwater elevation data after correcting for barometric pressure. This graph shows the instantaneous readings and a moving average, which averages measurements from the previous 5 days to smooth the data. The secondary y-axis represents the depth from the ground surface to groundwater. The pressure transducer stopped measurements on March 8, 2023; collection resumed following the March 19 site visit. Consequently, there is an 11-day gap in the data. Groundwater elevations were generally lowest in the winter and highest in the summer, with a peak elevation of 346.5 ft on August 7th, 2023. The minimum groundwater elevation was 344.3 ft on February 22nd, 2023.

Figure 3 depicts the groundwater elevation results from MW 270-1 and includes a correction for atmospheric pressure. Similar to MW 185-1, groundwater elevations were generally lowest in the winter and highest in the summer. The highest observed groundwater elevation at MW 270-1 was 346.6 ft on September 2nd, 2023. The lowest observed groundwater elevation was 344.8 ft on February 2nd, 2023.

3.4 MC 420

Figure 3 and Figure 4 show groundwater elevations in the MW 420-1 and MW 420-2 over the study period and include a correction for atmospheric pressure. Both plots show a similar trend with groundwater elevations increasing from August 2022 to a peak in May 2023. MW 420-1, in the left canal bank upstream of the check structure, collected a maximum groundwater measurement of 340.4340.4 ft on May 20th, 2023 and a minimum of 337.6 ft on October 22nd, 2023. MW 420-2, offset from the canal and located downstream of the check structure, collected a maximum groundwater measurement of 339.3 ft on May 20th, 2023, and a minimum of 337.0 ft on September 1, 2022.
