Gaining and Losing reaches along Little Turkey Creek (October 24, 2016)
Little Turkey Creek surface water flow rate steadily declines as the creek flows east across the
fault zone between the West and East Faults and eventually over the sedimentary Fountain
Formation to the east of the East Fault. These declining surface water flows indicate that the
creek is losing water to, and recharging, the underlying groundwater system. This is consistent
with potentiometric data from monitoring sites GW 2, GW-6 and GW-7 which show water levels
significantly below the creek water level and a downward vertical hydraulic gradient component.
The lateral hydraulic gradient within the fractured rocks underlying the reach of the Little Turkey
Creek valley between the West and East Faults is about 0.1. The significant steepening of the
hydraulic gradient within this reach suggests that the ability for the fractured rock to transmit
groundwater flow within this reach is considerably lower than that in the valley bottom to the west
of the West Fault.
