From email from Reclamation (Kara Lamb):
A Grand County contractor, working on the county’s Streamflow Management Plan, will be collecting data along the Blue River below Green Mountain Reservoir under multiple flow regimes. In order to accommodate this data collection it will be necessary to maintain the reservoir release at 200 cfs on Wednesday and Thursday and then 400 cfs on Friday and Saturday. The release rate will be ramped down to 200 cfs by Sunday evening.
