SWCD Monitoring Effects of High Flows

Posted on: February 26th, 2016 by Leslie_Zucker

Staff from the Ulster Coun­ty Soil and Water Con­ser­va­tion Dis­trict went out Thurs­day morn­ing to mon­i­tor the effects of high flows that occurred after Wednes­day night rains. The assess­ment crew vis­it­ed sev­er­al large stream restora­tion projects to see how they per­formed under high­er flows. The projects were com­plet­ed in recent years and expe­ri­enced flood stage for the first time on Stony Clove Creek at Wright Road, Stony Clove Lane, and near Chichester.

Quite a few streams in the Ashokan water­shed approached or exceed­ed bank­full stage. A stream is at bank­full when water just begins to spill out of the chan­nel onto the flood­plain. Streams that approached or exceed­ed bank­full stage were the Birch Creek, Wood­land Creek, Hol­low Tree Brook (a trib­u­tary to the Stony Clove), and the Stony Clove Creek, Lit­tle Beaver Kill and Eso­pus Creek at Cold­brook. The Bush Kill was just under bankfull.

Soil and Water Dis­trict staff flagged high water marks from Thursday’s event to sur­vey lat­er, and will do more exten­sive sur­vey after the water goes down. The crew took pho­tos to cap­ture some of the impacts. They also vis­it­ed USGS stream gage sites at Wood­land Creek and Lit­tle Beaver Kill to observe bank­full conditions.

At most loca­tions, stream flows peaked dur­ing the night, but if you do have pho­tos of a site that expe­ri­enced a lot of change, send them to the Stream Pro­gram office at info@ashokanstreams.org or call us at (845) 688‑3047.
