Bridget Deemer, doctoral student at Washington State University (WSU)- Vancouver, Canada, measured dissolved gases in the water column of Lacamas Lake in Clark County and found methane emissions jumped 20-fold when the water level was drawn down.
A fellow WSU-Vancouver student, Maria Glavin, sampled bubbles rising from the lake mud and measured a 36-fold increase in methane during a drawdown, according to a university statement.
