CONT: ... groundwater pumping will continue to be conducted in an environmentally conservative manner as was done during the 1990-91 and 1991-92 runoff years until there has been a substantial recovery in soil moisture and water table conditions in areas of Types B, C, and D vegetation that have been affected by groundwater pumping. The Standing Committee will establish annual pumping programs based on an evaluation of current conditions, including soil moisture level, water table depth, degree of water table recovery, soil type, vegetation conditions, the results of studies pertaining to vegetation recovery, and compliance with the goals of the Agreement.
CONT: The plant communities that we monitor require periodic connection to the groundwater for long-term survival and recovery from drought. Unfortunately, the on/off status often is not an accurate indicator of whether groundwater is reaching the plant root zone, but the rise of water above the water table due to capillarity is detected easily by the monitoring. Using the soil water and groundwater data, we determine which monitoring sites are connected with the water table and which still need water table recovery.
