ELTON CREEK, DS OF FREEDOM 7 BRIDGE, FREEDOM, NY. Bank erosion is threatening a farm road NRCS –Environmental Quality Incentives Program {EQIP} cost share with landowner Rural (farmland) Bed material: gravel-cobble-sand, incised Pool-riffle-pool regime, slope around 1% Average width 20-30 ft, 10-14 ft tall banks Partially spring fed. High-quality trout stream, not stocked, natural reproduction of Rainbow, Brown, & upstream, Brook Trout
