  1. RACKET CREEK @ ELK CITY LAKE NEAR INDEPENDENCE, KANSASPROJECT CONSTRUCTED DECEMBER 7-9, 2008

  2. RACKET CREEK NEAR INDEPENDENCE, KANSAS • Bank erosion is actively eroding and threatening infrastructure within a U. S. Army Corps of Engineers public campground • Rural, sparsely populated • Bed material: silts, clay, aluvium, deeply incised • Pool-riffle-pool regime, slope less than 1% • Average width 30-40 ft • 32 ft tall eroding banks are a public safety issue • One gully had a series of headcuts up to 4 ft tall.

  11. Racket Creek, Independence, KS Top bank Eroding bank approximately 32 ft tall stream channel 1 of 9

  12. Racket Creek, Independence, KS Dig a notch (2 ft deep and 4 ft wide) to tuck LPSTP closer to bank toe 2 of 9

  13. Looking DS. Tracked back hoe has dug out a notch (2 ft deep & 4 ft wide) to tuck LPSTP closer to bank toe CONSTRUCTION-RACKET CR. PIX BY DAVE DERRICK 12-8&9-2008

  14. Racket Creek, Independence, KS From top bank, dump stone down over hill 3 of 9

  15. Racket Creek, Independence, KS Tracked backhoe shapes stone into a Longitudinal Peaked Stone Toe Protection (LPSTP) with a crest height 4 ft above the base flow water surface elevation 4 of 9

  16. Racket Creek, Independence, KS Live Siltation Willow poles (termed Live Siltation) were then laid on the LPSTP at a rate of 3.5 poles per ft. Basal ends should be in vadose zone (capillary zone) 5 of 9

  17. Racket Creek, Independence, KS Soil dug from the opposite bank of the stream was used to “plant” the Live Siltation & also to provide a flatter slope for the eroded bank. 6 of 9

  18. Racket Creek, Independence, KS In some sections of the project the upper bank will be sloped to a stable angle of repose. 7 of 9

  19. Racket Creek, Independence, KS Rooted-stock plants will be added in spring 2009 to stabilize the bank, reduce high flow velocities, & provide a vegetated riparian corridor. 8 of 9

  20. Racket Creek, Independence, KS Seed & mulch all disturbed areas 9 of 9

  24. Looking US @ Key #1 with hoe digging Key #2. Key # 1 will be extended up the hill to top bank. The key will be vegetated with willow poles, filled with stone, backfilled with soil, with a berm at top bank to stop runoff flow down the key. CONSTRUCTION-RACKET CR.

  36. Root Production Method (RPM) • cRaZy gRoWtH WITHOUT CHANGING GENETICS (for oaks 0.8 inches @ DBH/year and 4 ft of growth per year are typical • A patented process • RPM Method developed by Wayne Lovelace in 1991 • Wayne Lovelace has 50 years experience in horticulture • RPM Method applied to over 250 different species-trees, shrubs, & grasses • Cost effective – 50 trees per acre vs 300-400 with seedlings • 60 acres of planted Mississippi River hardwood floodplain we observed (50 trees/acre, total 3,000 trees), only 7 trees dead

  37. Here is the teaser, an RPM Nuttal Oak, 7 years old, 7-inch dbh, & 35 ft tall. 92 degrees, we need shade PHOTO-DEB FREEMAN

  38. The RPM method is a 21 step patented process, with plants grown in bottomless trays. The tap root hits air and stops growing (air pruned). Plant is repotted twice, mychorrhiza inoculated twice, the rest is secret !!

  42. Three gallon container (removed), oak tree 6 months old, nothing but dense roots, allows for increased absorption of water, nutrients, and oxygen !!! Note mychorriza colonization (white area) Photo by derrick

  43. These RPM oaks were acorns in Feb, already 4-6 ft tall, several of these plants WERE PRODUCING ACORNS!!! Photo by derrick

  44. Acorns growing on a 6 month old Burr Oak. Typically these trees do not produce acorns during the first 30 years. Wayne says acorn production coincides with the wasting away of the tap root. Photo by derrick

  45. “Kimberley”, a natural cross between a Swamp White Oak & a Burr Oak discovered by Wayne’s wife. Over the last 20 years it has delivered 100 lbs of acorns per year (not diurnal). 50 Kimberlys per acre=5,000 lbs seed/food. Photo by derrick

  48. Looking DS @ crew planting the upper section of the project bend. Note flows have reshaped the active stream channel. Fine material deposited between the short Bendway Weirs. CONSTRUCTION-RACKET CR. PIX SHOT 3-18-2009

  49. Looking US @ the US section of the project bend. Channel within project is stable with sediment between Bendway Weirs. Bank has been graded & a few rooted-stock plants installed. CONSTRUCTION-RACKET CR. PIX SHOT 3-18-2009
