1. GOAL & FUNCTION-BASED DESIGN FOR RIPARIAN & STREAM SYSTEMS THE EIGHTEENMILE CREEK PROJECT PHASE I CONSTRUCTED AUG-SEPT 2003 PHASE II CONSTRUCTED JUNE 18-20, 2007 by Dave Derrick

2. EIGHTEENMILE CREEK IS A SUBURBAN, GRAVEL-COBBLE BED, POOL-RIFFLE-POOL REGIME STREAM IN A V-SHAPED VALLEY

3. SOME ASPECTS OF THE 18 MILE CREEK PROJECT PHILOSOPHY *As much as possible, techniques used were developed by observing nature and natural processes. **Design team worked with existing stream alignment and materials that were available ***Designers wanted to “work with” the stream (nudge, not fight) stream energy and stream tendencies

4. 18 MILE CREEK RESTORATION ***SOME PROJECT GOALS*** Aquatic habitat enhancement/restoration for Atlantic, Coho, and Chinook salmon, steelhead, Brown Trout, and bass. In response to incredible fishing pressure (9,000 TO 11,000 fisher folks yearly during runs), access and ingress and egress to the stream, encouragement for recreators to wade, back cast space for fly fishermen, safety, aesthetics (a natural look), & access trails for emergency personnel/vehicles were all driving project goals Stabilization of eroding banks and some riparian corridor vegetation (especially “leaning trees”) Need to artificially carbon-load the carbon depleted areas, and integrate long-term carbon into the project Re-establishment and enhancement of riparian buffer areas Revegetate all disturbed areas, establish “tough” plants for high foot traffic areas Minimize disturbance of downstream areas, especially with regard to habitat areas of T&E species Blanding’s Turtle

5. The "Locked Limb/Locked Log" Concept Consists of small trees and/or Small Woody Debris (SWD consisting of limbs, limbs with leaves, sections of small tree trunks, tree tops, etc.), anchored within or placed under structures, with limbs/logs protruding into deeper scoured areas to provide in-stream cover, vertical and horizontal structure, and areas of refugia. Can be either hand- or machine-placed Locked Limbs are typically less than 2” inches in diameter, Locked Logs are greater than 2 inches in diameter

26. Large single stones placed in a flowing channel. Three versions: 1.) Top of the stone set at an elevation slightly lower than the typical base- flow water surface elevation. When sited correctly, the accelerated flow over the top of the stone will change from subcritical to supercritical flow, & further downstream back to subcritical (usually with a weak hydraulic jump). The hydraulic jump will entrain air & aerate the stream. 2.) Stone crest set just below the base flow water surface elevation results in an acceleration of the water moving over the top of the stone, with “standing waves” forming downstream of the stone. 3.) Stone crest set slightly above the base flow water surface, resulting in a V- shaped wake and flow split with a double return eddy flow pattern DS of the stone. However, these stones might be used as perches for predators. The constant movement & rippling of the water from the three types of Hydraulic Cover Stones results in a type of cover, “hydraulic cover”, masking fish location from the view of predators. The stones also provide resting areas & in-channel refugee for fish during high energy, high-flow events. Hydraulic Cover Stones are especially useful in sections of the stream with little in-channel structure, or vegetative cover, or undercut banks. Hydraulic Cover Stones (HCS)

32. Functions of Hydraulic Cover Stones Provides micro-topography (scour & deposition) Provides diversity of velocities Provides “hydraulic cover”, turbulence, return currents, eddy fences, internal distortion, pressure zones Provides feeding lanes for fish Provides shape cover & solid substrate for benthics Provides refugia Dissipates energy Can aerate water, or de-gas super-saturated water

33. Looking DS, note locations of Hydraulic Cover Stones during unusually low flow conditions

41. PHASE II OF THE EIGHTEENMILE CREEK PROJECT CONSTRUCTED JUNE 18-20, 2007

42. PHASE II FUNCTIONS Constructed immediately DS of the 2003 restoration project FUNCTIONS: Narrowed stream to increase low flow velocities & provide cover, holding areas, solid substrate, and also allow off-channel areas to revegetate as emergent aquatic marshes Provide access for fishermen Provide aquatic habitat (diversity and complexity) Provide hydraulic cover (disturbance of surface water, difficult for predators to see fish)

54. SMILES, FROWNS, KICKERS, SINGLE HYDRAULIC COVER STONES, CLUSTERS OF HYDRAULIC COVER STONES All in-channel, as much as we could fit in and still provide functions listed below, all in the name of good fishing. FUNCTIONS: Provide cover for fishes, dissipate stream energy, speed current through narrow deep mini channels, divert flow, redirect, cause eddy fences, calm water, holding areas, feeding lanes, diversity & complexity of flow both vertical & horizontal, & surface disturbances
