There’s a lot more snow above Cody – that means a lot more melt.
The Bureau of Reclamation Office in Billings has released an updated list of their snow-melt predictions for the entire Bighorn River Basin. The report lists the forecasted acre-feet of water for six major bodies of water in the Basin – Bighorn Lake, Boysen Reservoir, Bull Lake Reservoir, Bull Lake Creek, Wind River, and of course, the Buffalo Bill Reservoir.
When we first covered this story on KODI, The April through July inflow to Buffalo Bill Reservoir was forecast at 675,000 acre feet of water – 91 percent of the 30 year average of 742,600 af. Now, nearly two months later, the snowmelt forecast is 840,000 af, which is 113% of the 30-year average of 742,600 acre feet. That’s a little bit more than before. And we haven’t even gotten into spring yet.
