  2. THE EIGHTEENMILE CREEK PROJECT PHASE I CONSTRUCTED AUG-SEPT 2003by Dave Derrick

  3. At higher flows energy is vectoring straight into 14 ft tall eroding bank Pix by Mark Seider

  4. My sneaker Close-up of large stones, these were hand selected & are 3 ft by 3 ft with two sides flat.

  5. Tough to specify stone. Call some quarries to see what is available. Stone might be called “ledge rock, shelf rock, flats, or big flats”. Thickness will be determined by how it is fractured & breaks out during blasting. Must be fairly flat on two sides. Inspect stone, then spec. minimum measurements, say 2 ft x 3 ft by 4 ft (can be exceeded, but cannot be smaller). When ready for construction go to the quarry & hand pick the stone.

  6. Schematic detail of Great Wall with backfill & plantings (does not include LUNKERS or keys) Toe stones are placed, drilled through stone & 1 ft deep into underlying bedrock, metal rod is driven into the hole, excess cut

  7. Stepped back design allows fishing folk to use different levels Pix by Derrick Looking DS at the Great Wall, it is approx. 300 ft long, notice upper bank is not smoothed, seeded, or planted yet

  8. Looking DS, placing the first row of stones on bedrock

  9. Detail of Great Wall of Newfane & Turbidity Curtain from project Plans & Specifications Only the bottom row of stone is drilled & pegged to bedrock Shot rock used for foundation

  10. Hand drilling completely through the stone & one ft deep into bedrock. Stones now pinned with a 4 ft long, one inch diameter rebar (not cut off yet)

  11. Drilling completely through the stone & one ft deep into bedrock. Stones now pinned with a 4 ft long, one inch diameter rebar (not cut off yet)

  12. Bottom row of stones drilled and pinned with 1 inch diameter rebar

  13. Drilling completely through the stone & one ft deep into bedrock. Stones will be pinned with a 4 ft long, one inch diameter rebar. Shot rock foundation in foreground. Flow from dam aimed right at wall!! 8” Surge stone base for large walk-able bank protection

  14. Erosion Control Blankets supplied by Indian Valley Industries, Inc. Coir 700 mat (700 grams per square meter). 100% spun coir, with an open area of 50%. 100% biodegradable.

  15. Pix by Derrick Looking US. 5 growing seasons later. Riparian plantings are robust, June 7, 2009. Scale, daughter Dana is 5 ft 2”

  16. Since construction this project has been used extensively for public outreach (adult and children) & as a teaching platform for fellow professionals.

  17. I got to fly in the DEC/State Police helicopter. Looking downstream, red line is the Great Wall of Newfane - Feb 2, 2005

  18. Peaceful co-existence “combat” fishing

  19. BIG THAW PLUS RAIN = HIGH STAGES Feb 6, 2008

  20. Looking US @ the Great Wall. Power generating dam in background. Post-Project-18 Mile Creek, Phase II-Feb 6, 2008, Pix-Vic

  21. PROJECT CONSTRUCTED June 2006 CHAUTAUQUA CREEK ICE DAMAGE REDUCTION PROJECT –Near its mouth @ Lake Erie

  22. CHAUTAUQUA CREEK ICE DAMAGE REDUCTION PROJECT –Near its mouth @ Lake Erie • Severe scour from ice and high flow velocities on the right descending bank had resulted in an overwidened section of stream. • Mid-channel sediment bars, mouth of creek @ Lake Erie clogged • No holding areas or habitat for steelhead • A heavily used public fishing section of the stream

  23. Single Stone Bendway Weirs (pegged to bedrock), spaced 50 ft apart NEED PLANS & SPECS Trench Stone (drilled & pegged) Stacked Stone Wall (bottom row drilled & pegged) Key Sloped Stone using “Big Flats”, most 5 ft by 5 ft by 2 ft thick Key Key Flow Key Key Key Key

  24. DRILLING & PEGGING TOE STONES & SINGLE STONE BENDWAY WEIRS WITH METAL RODS INTO BEDROCK

  25. Construction June 2006. Looking DS @ 2 hoes jack hammering a footer trench through a layer of weathered stone. Would not need to do this if stone was not weathered. Pix by derrick

  27. Dave Spann of Chautauqua County Soil & Water Conservation District with a 7 ft long, 1 5/8 inch diameter solid bar. Dave did everything from writing the grant to providing extraordinary project management. On time & under budget!!!! Pix by Joe Galati

  28. This type of drill needs a flat solid foundation. Construction June 2006. Looking DS. Drilling 2 inch holes to peg stone to bedrock. The 2 inch bit was the only one they had on hand… Pix by Joe Galati

  30. Construction June 2006. Looking US. Metal pinning rods not cut off yet. Pix by derrick

  31. Construction July 2006. Cut off solid metal rod in drilled hole pinning stone to underlying bedrock Pix by Joe Galati

  32. Construction June 2006. Looking US during placement of “big flat” stones on the backfill/filter stone. Pix by derrick

  33. EVERYBODY WANTS COSTS, FOR ONCE WE HAVE COSTS!! Big thanks to Dave Spann, Chautauqua County Soil & Water Conservation District for these figures.

  34. CONSTRUCTION COSTSDoes not include admin, design, permitting, program management, construction oversight, or plant installation Total: $200,584.
