1 RACKET CREEK @ ELK CITY LAKE NEAR INDEPENDENCE, KANSAS PROJECT 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.

10 STEP-BY-STEPS FOR RACKET CREEK All drawings by Dave Derrick

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

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

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

15 4 of 9 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

16 5 of 9 Racket Creek, Independence, KS 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 ) Live Siltation

17 6 of 9 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.

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

19 8 of 9 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.

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

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. PIX BY DAVE DERRICK 12-8&9-2008

36 Crew ready, RPM plants ready, let’s plant!! CONSTRUCTION-RACKET CR. PIX SHOT 3-18-2009

37 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

38 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

39 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 !!

43 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

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

45 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

46 “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

57 Stream Project Functions: Fully functioning both hydraulically & environmentally. Multiple protection redundancy. Longitudinal Peaked Stone Toe Protection provides a robust adjustable bank toe protection. Bendway Weirs move scour & thalweg away from attacked bank, with velocities reduced within weir field & on bank. Live Siltation, pole plantings, & rooted-stock plants provide roughness & reduce near-bank flow velocities. Roots strengthen bank & bind soil. Bank & top bank rooted stock plantings will provide stability and a continuous riparian corridor.
