The lower Henrys Fork region in eastern Idaho includes the plains and low benches between Ashton and the junction of Henrys Fork and Snake River. The northwestern and western parts of the area are part of the Snake River basalt plain. The central part of the area is occupied by alluvial plains of the Snake, Teton, and Falls Rivers and of Henrys Fork. The alluvial deposits are underlain by basalt. The southeastern part of the area is a bench (Rexburg Bench), chiefly on silicic and ibasaltic volcanic rocks, which rises gradually to mountain peaks (Big Hole Mountains) southeast of the area. Irrigation wells open to the basalt under the Snake River Plain and the 'basalt and sands and gravels under the .alluvial plains yield large amounts of water with small drawdowns. Irrigation wells in the silicic volcanic rocks and the interbedded ash, pyroclastics, and sedimentary deposits beneath the Rexburg Bench generally yield much less water. The regional water table slopes southwestward beneath the basalt and alluvial plains. It is recharged by precipitation that infiltrates into the ground in the headwaters of Henrys Fork and Falls, and Teton Rivers and by water that moves downward from an extensive perched water body caused by seepage from stream channels and surface-water irrigation. The perched water in part moves vertically down to the regional water table and in part laterally to the streams. Ground water beneath the Rexburg Bench moves generally northwestward to join the regional groundwater body beneath the alluvial and basalt plain, (but this area contributes very little recharge to the main aquifer body. Recharge to the regional water table is estimated to average 725,000 acre-feet annually. The regional water table is below the level of the streams in the area, and ground water in the main aquifer, therefore, is not tributary to the streams. Pumping from the regional groundwater reservoir for irrigation or other uses would have no effect on streamfiow or surface-water rights within the Study area. However, depletion of the underflow would eventually reduce the inflow to American Falls Reservoir, unless the depletion was offset by additional recharge. Total withdrawals of ground water for irrigation in 1962, principally in the Rexburg Bench, were estimated to be 25,000 acre-feet. About 10,000 acre-feet was 01 C2 CONTRIBUTIONS TO THE HYDROLOGY OF THE UNITED STATES withdrawn for domestic, municipal, and stock supplies. These withdrawals caused no significant decline in the water table. In the Ashton area, surface-water irrigation has caused water to be perched in basalt above the silicic volcanic rocks, and much of this perched water contributes to streamflow. Some ground water can be pumped from the basalt for irrigation and other uses. If ground water were pumped for irrigation, the flow of Henrys Fork would be decreased by the amount of pumped water consumed by crops. Water pumped for nonconsumptive use would have little effect on streamflow. Groundwater prospects for irrigation in the Falls River area are not en...

“…Between 2009 and 2014, the IWRB initiated a “pilot” phase of the recharge program funded by numerous one‐time, State allocations. The IWRB was able to build upon numerous MAR studies, investigations, and pilot projects, starting in 1962, that had been conducted throughout the ESPA (Mundorff et al 1962; Norvitch et al 1969; Sullivan et al 1999; IDWR 1999; Johnson et al 1999; Blew 2005; Johnson 2012). Key accomplishments during the pilot phase included the development of partnerships with canal operators along with the identification and testing of potential managed recharge sites.…”

The Eastern Snake Plain Aquifer (ESPA), Idaho's largest and most productive aquifer, has experienced substantial decline since the early 1950s due to changing climate conditions, increased demands, and evolving irrigation practices. To address this issue, the Idaho Water Resource Board (IWRB) developed the ESPA Comprehensive Aquifer Management Plan (CAMP). The CAMP outlines methods and goals for the replenishment of the aquifer, including the development of a managed aquifer recharge (MAR) program. In 2014, the State of Idaho has provided dedicated, long‐term funding for the MAR with the goal of achieving an average annual recharge rate of 0.3084 km3 (250,000 ac/ft). Since then, the IWRB has invested over $16 million dollars in investigations and infrastructure improvements to support MAR operations and program build‐out, resulting in an addition of over 62.3 m3/s (2,200 cfs) of instantaneous MAR capacity and total programmatic recharge of over 2.2203 km3 (1.8 million acre‐feet). Overall, the program has added an average of 0.3207 km3 (260,000 ac/ft) per year to the aquifer. Utilizing existing infrastructure and the IWRB's natural flow water rights has significantly reduced programmatic costs. The program's cost for conducting MAR since 2014 is $0.01 per cubic meter or $18 per acre‐foot accounting for capital cost, conveyance fees, operation and maintenance, and monitoring cost. Future capacity increases are planned to further assist the program in capturing excess water when it is available.
