NW Wyoming Water Supplies Still Ample

While Wyoming’s snowpack has dropped to 22% of the 30-year average now, the Natural Resources Conservation Service says the river basins of Northwestern Wyoming are in better shape than the rest of the state.  According to their report, those basins remain in the 50 to 70 percent range.  Snow-water content is calculated at 48% of normal in the Snake River Basin, 76% of normal in the Madison-Gallatin Basin and 71% of normal in the Yellowstone basin.  Actual precipitation was measured at 90% of normal in the Snake River Basin, 110% of normal in the Madison-Gallatin Basin and 98% of normal in the Yellowstone Basin.  Meanwhile, the reservoirs throughout the Upper Snake River Basin average 86% full.  Specifically, Grassy Lake is at 101% of its capacity and Jackson Lake is 95% filled.  Palisades Reservoir remains at 76% of its storage capacity and filling. Meanwhile, while much of the state is considered abnormally dry at this time, the Northwestern corner of the state is still considered about average.
