Ice on the creek that has formed over a high volume flow might be going through some adjustments when lower flows begin.
Beginning at 1pm on Friday January 28, 2011, the high-volume flows from the Ashokan Release Channel switched from the turbid West Basin to begin releasing cleaner water from the East Basin. This will continue for three days to help flush out turbidity from the Lower Esopus Creek, after which lower flows are expected. As water levels drop, the creek ice is expected to readjust, which may cause cracking and ice instability.
The clear water flush of the creek is a short term solution, but it is a first step to having clean water releases for stream health. This will need to be followed up with monitoring to understanding the harm done to the Lower Esopus Creek and downstream communities by the prolonged, high-concentration turbid water releases from the West Basin of the Ashokan Reservoir.
