. Increased amounts of snow could be accumulated over the recharge zones of shallow productive aquifers . Increased snow accumulation is shown to be effective in increasing the amount of recharge water reaching these aquifers The Turner-Hogeland Aquifer occupies most of the Turner-Hogeland plateau in northern Montana, The Turner-Hogeland Artificial Recharge Demonstration Site was located in a glacial outwash channel that was itself incised into glacial till and lined with coarse, unsorted glacial outwash, The outwash deposits sit directly on the deposits that contain the Turner-Hogeland Aquifer. Static water levels under the demonstration site ranged from 22 to 26 feet below land surface, Water in the Turner-Hogeland Aquifer is used for domestic, stock watering, and irrigation purposes, _ Well 10 .

Construction at the demonstration site included 18 wells, Tall wheatgrass barriers were seeded on the northern part of the site. The 80-acre project site was divided into two 40-acre plots, On the northern (recharge) plot, tall wheatgrass barriers were planted to serve as a snow entrapment mechanism. The wheat-grass formed semi- permeable barriers that disrupted wind movement and caused snowdrifts to form, On the southern (control) plot, wheatgrass barriers were not planted, and normal crop-fallow farming techniques were employed, Water stored on the land surface during the winter months became meltwater in the early spring that entered the land surface by direct gravity infiltration through the soil zone, There was no treahnent of the water prior to infiltration, Recharge water quality was determined by collecting and melting snow, bottling the resulting water, and analyzing the samples to determine concentrations of analytes ranging from common inorganic constituents to herbicides/pesticides. Water quality in the Turner- Hogeland Aquifer was monitored for the same parameters at points upgradient of the demonstration site (well 7), under the control plot (well 8), under the recharge plot (well 9), and downgradient of the site (well 10). Samples were collected one to three times annually. The Turner-Hogeland Artificial Recharge Demonstration Site was operated cooperatively by the Montana Bureau of Mines and Geology (MBMG) and the US, Bureau of Reclamation, Other cooperators were the Blaine County Conservation District and L. and M. Farms of Chinook, Montana. L. and M, Farms owns and operates the field where the project was developed, 2 .
