USGS Releases Report on Turbidity

Posted on: January 20th, 2015 by Leslie_Zucker
The U.S. Geological Survey (USGS) released a report in late 2014 that summarizes the results of suspended sediment and turbidity monitoring in the upper Esopus Creek  through 2012. Monitoring was supported in part by the Ashokan Watershed Stream Management Program. The report titled “Turbidity and suspended sediment in the Upper Esopus Creek watershed, Ulster County, New York” is available at this link:  Findings show that during the study period (2010 to 2012), flows were generally higher than in the past and resulted in higher SSC and turbidity values. Stony Clove Creek had the highest SSC and turbidity values of any of the tributaries in the upper Esopus Creek watershed, and these values were in fact higher than the values measured at Coldbrook, the watershed outlet. High SSC and turbidity levels were measured at Beaver Kill, Birch Creek, and Woodland Creek during the study, but the high concentrations were of short duration. Turbidity values and SSCs were rarely high at the headwater site on the Esopus main channel at Oliverea, Hollow Tree Brook, and Little Beaver Kill.
