AB: Management of seasonal wetlands (Refuges) for waterfowl in the San Joaquin Basin of California has been complicated by water quality requirements in the San Joaquin River, into which the wetlands drain. In particular, releases of salt and boron to the river are bound by a Total Maximum Daily Load requirement. At the same time, the US Bureau of Reclamation is exploring opportunities for conjunctive use of groundwater from beneath these wetland areas, which will likely yield pumped water of higher salinity than the surface water currently supplied to the Refuges. This study uses real-time data collection and adaptive management to encourage releases of saline water to coincide with periods of increased assimilative capacity in the river (i.e. elevated rainfall/runoff levels and timed releases from reservoirs upriver.) The wetland system is modeled using the Mike She and Mike 11 software packages, developed by the Danish Hydrologic Institute. The purpose of the model is the forecasting of assimilative capacity, estimation of response to wetland drainage, and simulation of migration of salinity in groundwater.
