What is a Stream Feature Inventory (SFI)?

Posted on: July 7th, 2020 by Tim Koch

Hold on tight for a bit of reverse engineering:

The Ashokan Water­shed Stream Man­age­ment Pro­gram (AWSMP) is a col­lab­o­ra­tion between Cor­nell Coop­er­a­tive Exten­sion of Ulster County, the Ulster County Soil & Water Con­ser­va­tion Dis­trict, and the New York City Depart­ment of Envi­ron­men­tal Protection.

All of the AWSMP’s stream man­age­ment activ­i­ties are under­taken in coor­di­na­tion with a local Stake­holder Coun­cil. The Stake­holder Coun­cil uses rec­om­men­da­tions from Stream Man­age­ment Plans to guide their deci­sion mak­ing. Man­age­ment plans con­tain a com­pre­hen­sive review of stream char­ac­ter­is­tics, data, maps, and rec­om­mended man­age­ment strategies.

The large amount of data and obser­va­tions required to write a man­age­ment plan for a stream come from a Stream Fea­ture Inven­tory (SFI). This is where the rub­ber meets the road, or, where the wad­ing boots meet the stream bed.

Dur­ing a SFI, AWSMP staff from the Ulster County Soil & Water Con­ser­va­tion Dis­trict walk a stream from top to bot­tom, col­lect­ing data on erod­ing stream banks, log­jams, and infra­struc­ture. These data are then ana­lyzed and ulti­mately used to write a stream man­age­ment plan.

Join AWSMP Stream Edu­ca­tor Tim Koch as he joins the assess­ment crew on a SFI of the Elk Bushkill Creek in the Town of Shan­daken. This SFI is part of a larger effort by AWSMP to assess mul­ti­ple head­wa­ter trib­u­taries of the Eso­pus Creek, includ­ing McKin­ley Hol­low Creek and Lit­tle Peck Hol­low Creek. These trib­u­taries may be con­tribut­ing exces­sive sed­i­ment loads to the upper Eso­pus  Creek in the Oliv­erea val­ley. Excess sed­i­ment sup­ply leads to aggra­da­tion, or sed­i­ment “fill­ing in” the stream, which can sub­se­quently trig­ger bank ero­sion and raise flood ele­va­tions.  SFI’s of the Eso­pus Creek head­wa­ters may help to locate and pri­or­i­tize restora­tion project sites aimed at reduc­ing the sed­i­ment sup­ply reach­ing the valley.

Stay tuned in the com­ing months for a SFI report on the Eso­pus Creek Head­wa­ters and for a new stream man­age­ment plan for the Lit­tle Beaver Kill in the Town of Woodstock.
