Contact: Doug Fisher, dfisher@OCSWCD.ORG Location: A couple different locations on Onondaga Cr. in the Tully Valley, near LaFayette, NY.
THE NATURAL, THEN CONSTRUCTED BOIL-UP POOL ON UPPER ONONDAGA CREEK, NEAR SYRACUSE, NEW YORKConstructed May 2006The go-to guy, Mark Schaub with the Onondaga County Soil and Water Conservation District, Lafayette, NY.
Looking US toward the left bank. Note the interesting natural hook causing a Boil-Up pool. 4/18/2006
Not much of a hook, but very effective at forming a natural deep, circular, scour pool. 4/18/2006
Looking DS, construction has begun on DS riprap and Engineered Rocked Riffle. 5/24/2006 From Mark Schaub
Looking DS, stone in, but not a great semi-circle yet-5/24/06 From Mark Schaub
Looking DS, bank stone & kicker in, still not a good semi -circle 5/24/2006 From Mark Schaub
Looking US, note how bank kicks current, just a little more tweaking needed (pull some toe stone back) 5/24/2006 From Mark Schaub
The next day, flow right to left. All angles and circles correct, note flow over curved kicker, truly a thing of beauty!!! From Mark Schaub
Looking DS. Planform now consists of two pools & a riffle within the bend 5/25/2006 From Mark Schaub
Looking US at the Boil-Up Pool at bankfull stage. Note thalweg down the center of the stream From Mark Schaub

3 YEARS AFTER PROJECT COMPLETIONPhotos by Derrick JUNE 18, 2009
Looking US @ the Boil-Up Pool 3 yrs after construction, Boil-Up working well even under base flow conditions, and streamside veg coming on strong. 3 YEARS LATER - Onondaga Creek-Site 5-D. -DERRICK 6-18-2009

TRANSPLANTING EXISTING VEG AND/OR ROOT MATS WITH THE TRACKHOE{2 MINI CASE STUDIES}
ONONDAGA CREEK SITE 5-D Diamond-Oriented Traffic Control Stones with Single Stone Bendway Weirs(MINI CASE STUDY #1)
DIAMOND -ORIENTED TRAFFIC CONTROL STONES {TCS} WITH BEDLOAD BENCH IN BETWEEN, WITH TRANSPLANTED VEGETATION ON TOP OF TCS & BEDLOAD BENCH WITH SINGLE-STONE BENDWAY WEIRS ON EVERY 4th TCS .
TCS were typically 3 ft by 3 ft by 3 ft, spaced 6 to 8 ft apart, with bedload material choked in between forming a continuous bench. Vegetation was pulled down from top bank & placed on the bench. Every 4th TCS was keyed into the bank & had a single-stone Bendway Weir added to the stream end.

Diamond-Oriented Traffic Control Stones with Single Stone Bendway Weirs Key TCS TCS TCS Key TCS TCS SSBW TCS TCS TCS SSBW Key TCS SSBW Square stones (3 ft by 3 ft by 3 ft) placed with a sharp edge facing upstream, designed to “kick” flow off the bank, must be keyed into the bed & bank, spaced 6 to 8 ft apart, every 4th one should be keyed into the bank. Every 4th stone has a Single Stone Bendway Weir.

Diamond-Oriented Traffic Control Stones with Single Stone Bendway Weirs Thalweg is dug and that bedload material is placed between the Traffic Control Stones to form a bench at the same height as the TCS.

Diamond-Oriented Traffic Control Stones with Single Stone Bendway Weirs Plants, root mass, and soil was pulled down from the vertical outer bank to provide streamside vegetation. The mid & upper bank was sloped and seeded.

Slide even more veg down the slope. Note long “Instant Shade” over stream
