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

TRANSPLANTING EXISTING VEG AND/OR ROOT MATS WITH THE TRACKHOE{2 MINI CASE STUDIES}
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.
