The goal of the Upper Columbia Wetland Vulnerability Assessment project is to determine the various types of wetlands in the upper Columbia Wetlands based on their hydrologic functions, determine which types of wetlands are more vulnerable to drought (and climate change), and to assess which wetlands may be amenable to conservation actions to prevent the loss of water. This work is classifying the wetlands based on their hydrologic and morphological characteristics. In May 2020, the team installed continuous water level loggers in 37 wetlands, 2 in the Columbia River, and 4 drive point piezometers to monitor shallow groundwater input in 4 sites. Precipitation and evaporation are also available from local data. Together, these data will be used to construct water balances of the monitored wetlands for extrapolation across all wetland types in the upper Columbia.
