With reduced Sentinel-1 coverage following the hardware anomaly onboard Sentinel-1B, the Winter Hydrology and Remote Sensing Desk is augmenting our River Ice Surveillance with high resolution earth observation satellites (Landsat and Sentinel-2).  In today's discussion we summarize ice conditions on portions of the Wind, Bighorn, Shoshone, Clarks Fork Yellowstone, White, Cheyenne, Belle Fourche, and Missouri rivers in MBRFC's region. For NCRFC's region, we had some good shots of portions of the Wisconsin, Mississippi, Wapsipinicon, Cedar, Iowa, Skunk, Des Moines, Rock, and Illinois Rivers.
