“…Declines of 20 ft or more mostly occurred in areas where the city does not have production wells. This is a change from previous patterns of water-level change where the largest declines occurred within the CENWWF where Wichita has production wells (Hansen and Aucott, 2010). Annual city pumpage from the study area, almost all of which was from the CENWWF, remained less than 22,000 acre-ft for 2010 through 2013, whereas annual irrigation pumpage from the study area increased by more than 25 percent from about 32,100 acre-ft in 2010 to about 45,500 and 40,800 acre-ft in 2011 and 2012 ( fig.…”

“…About one-third of the pumpage from the Equus Beds aquifer occurs in the study area (Kansas Department of Agriculture, 2011). Irrigation and city use dominate pumpage from the Equus Beds aquifer in the study area (Hansen and Aucott, 2010). Pumpage from the study area in 2012 (latest year for which pumpage is available) was about 40,800 acre-feet (acre-ft) for irrigation and about 21,600 acre-ft for the city of Wichita (Kansas Department of Agriculture, and Kansas Geological Survey, 2014).…”

“…Ziegler and others (2010) used a depth of 80 ft as the dividing point between the shallow and deep parts of the Equus Beds aquifer. An analysis of the GMD2 and city of Wichita well clusters in the study area by Hansen (2011b) indicated about 90 percent of the GMD2 zone A wells and shallower wells in city well clusters were completed and screened to a depth of 80 ft or less; about 90 percent of the GMD2 zone C wells and deeper wells in city well clusters were completed and screened to a depth of greater than 80 ft. Thus, use of the 80 ft depth as the dividing point between shallow and deep parts of the Equus Beds aquifer was reasonable when assigning the city of Wichita monitoring wells that were not in clusters into either the shallow or deep parts of the Equus Beds aquifer.…”

“…The storage-volume changes since 1993 shown in table 3 were computed by two methods. In the first method, the "since predevelopment" value for the beginning of the period was subtracted from the "since predevelopment" value for the end of the period, which is the method used in previous reports by Aucott and Myers (1998), Aucott and others (1998), Hansen (2007, 2009a, 2009b, 2011a, 2011b, and Hansen and Aucott (2001. The second method of storagevolume changes since 1993 were computed by using the water-level-change rasters.…”

The city of Wichita, Kansas uses the Equus Beds aquifer, one of two sources, for municipal water supply. To meet future water needs, plans for artificial recharge of the aquifer have been implemented in several phases. Phase I of the Equus Beds Aquifer Storage and Recovery (ASR) Program began with injection of water from the Little Arkansas River into the aquifer for storage and subsequent recovery in 2006. Construction of a river intake structure and surface-water treatment plant began as implementation of Phase II of the Equus Beds ASR Program in 2010. An important aspect of the ASR Program is the monitoring of water quality and the effects of recharge activities on stream conditions. Physical, chemical, and biological data provide the basis for an integrated assessment of stream quality. This report describes protocols for collecting streamflow, water-quality, streambed-sediment, periphyton, macroinvertebrate, fish, and habitat data as part of the city of Wichita's hydrobiological monitoring program (HBMP). Following consistent and reliable methods for data collection and processing is imperative for the long-term success of the monitoring program.

The part of the Equus Beds aquifer in southwestern Harvey County and northwestern Sedgwick County was developed to supply water to the city of Wichita and for irrigation in south-central Kansas. The 165 square-mile study area represents about 12 percent of the 1,400 square-mile Equus Beds aquifer and accounts for about onethird of the withdrawals from the aquifer. Water-level and storage-volume decreases that began with the development of the aquifer in the 1940s reached record to nearrecord lows in January 1993. Since 1993, generally higher water levels and partial storage-volume recoveries have been recorded in the aquifer. Potentiometric maps of the shallow and deep layers of the aquifer show flow in both aquifer layers is generally from west to east. The July 2011 water-level altitudes in the shallow aquifer layer ranged from a high of about 1,470 feet in the northwest corner of the study area to a low of about 1,330 feet in the southeast corner of the study area; water-level altitudes in the deep aquifer layer ranged from a high of about 1,445 feet on the west edge of the study area to a low of about 1,340 feet in the southeast corner of the study area. In the northwest part of the study area, water-levels can be more than 60 feet higher in the shallow layer than in the deep layer of the Equus Beds aquifer. Measured water-level changes for August 1940 to July 2011 ranged from a decline of 43.22 feet to a decline of 0.17 feet and averaged 12.45 feet. The largest August 1940 to July 2011 water-level changes of 30 feet or more occurred in the northern part of the study area centered about 2 and 4 miles east of Burrton, Kansas. The change in storage volume from August 1940 to July 2011 in the study area was a decrease of about 209,000 acre-feet. This volume represents a recovery of about 46,000 acre-feet, or only about 18 percent of the storage volume previously lost between August 1940 and January 1993. The largest post-1993 storage-volume recovery to date in the study area was about 161,300 acre-feet in July 2010. The approximately 115,000 acre-feet decrease in storage volume from July 2010 to July 2011 in the study area represents a depletion of about 71 percent of storage volume previously recovered from January 1993 to July 2010; about 105,000 acre-feet of this decrease occurred between January and July 2011. Most of this depletion probably is because of decreased recharge from precipitation that at 9.26 inches for January through July 2011 was less than one-half of normal and increased irrigation pumpage associated with less-than-normal precipitation; city pumpage probably was less than average. For the study area, irrigation pumpage for 2011 was estimated at about 42,700 acre-feet and 2011 city pumpage was estimated at about 21,400 acre-feet. The approximately 29,900 acre-feet decrease in storage volume from July 2010 to July 2011 in the central part of the study area represents a depletion of about 31 percent of the storage volume previously recovered from January 1993 to July 2010. A major factor in the...
