Cyanobacteria blooms turned Blue Mesa Reservoir green from September through November 2021, when water levels were among the lowest on record. The OLI (Operational Land Imager) on Landsat 8 captured this image (right) of a bloom on November 17, 2021, when the water was near its lowest level; the left image shows the same area on November 15, 2017, when water levels were closer to normal.

2021年9月至11月，蓝梅萨水库因蓝藻水华而呈现绿色，当时水位处于历史最低记录之一。陆地卫星8号上的OLI（陆地成像仪）于2021年11月17日拍摄了这张水华图像（右图），当时水位接近最低点；左图显示的是2017年11月15日同一区域的情况，当时水位更接近正常水平。NASA地球观测站 / 劳伦·多芬
