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.
