We are collecting rain and snow samples to develop a water balance for the region based on the isotopes of oxygen and hydrogen in the water molecule. This is part of a larger project that is evaluating the past, present, and future of water resources in the Columbia Basin. More information on the project can be found here: http://janicebrahney.weebly.com/columbia-basin.html and here: https://www.instrumentl.com/campaigns/janicebrahney/
