STREAM RESTORATION FIELD TRIP FOR TNF FOREST PLAN REVISION Date: May 2, 2018 Meeting Time: 9:30 AM Meeting Place: Alderwood Campground Important Field Trip Logistics: • Try to carpool to the site, if possible • Bring water, snacks, sunscreen, and your own lunch • The first site will be Haigler Creek. The second site, Canyon Creek, will be optional. Canyon Creek is an hour and fifteen minutes away from Haigler Creek. Background The Tonto National Forest (TNF) is revising its Forest Plan Canyon Creek Stream Restoration and is asking partners for input and support on stream restoration into the future. Trout Unlimited and the Arizona Game and Fish Department have conducted successful restoration projects on Haigler Creek, Canyon Creek, and other streams of the TNF, and are co-leading this field trip. On the field trip, participants will share their experiences with stream restoration and identify potential future roles in enhancing stream health on the TNF. Figure 1: Photo of Haigler Creek Field Trip Objectives • Establish a shared understanding of the use of stream restoration as a tool to achieve desired conditions • Share examples of successful projects and the range of effective tools and techniques • Identify how partners could be involved in helping the TNF achieve desired conditions for streams STREAM RESTORATION FIELD TRIP FOR TNF FOREST PLAN REVISION Agenda Stop 1: Alderwood Campground 9:30AM Introduction and desired conditions • Introductions – All participants • Logistics – Southwest Decision Resources • Overview of stream restoration in the new Forest Plan – Kenna Belsky, Grant Loomis, and Robert Madera, Tonto National Forest o Definition and context of desired conditions o Other efforts, and how they relate to the Forest Plan • Haigler Creek Restoration Project – Curt Gill, AZ Game and Fish Dept. • Discussion: Desired conditions applicable to sites across the Tonto National Forest Stop 2: Haigler Canyon Campground 11:00AM Successful methods and approaches • Examples of other successful projects/efforts: o Canyon Creek (passive and active restoration) – Curt Gill and Kelly Wolff, AZ Game and Fish Dept. o Dude Creek (Gila Trout reintroduction) – Nate Rees, Trout Unlimited o Cherry Creek (channel stability & water rights) – Alan Haden, Natural Channel Design; Grant Loomis, Tonto National Forest • Discussion: Methods and outcomes that the Tonto National Forest (and partners) should aim for in future restoration projects 12:00PM Lunch Stop 3: Bridge site 1:00PM Multiple use and management actions • Overview of the site and the effects of the bridge – Kenna Belsky, Tonto National Forest; Curt Gill, AZ Game & Fish • Narrative on possible management actions to be done o 4FRI Flexible Toolbox for Aquatics – Joe Miller, Trout Unlimited; Kelly Wolff, AZ Game and Fish Dept. o Other efforts to engage in: .

Arnett Creek – Tony Bush, Tonto National Forest • Discussion: What actions could be taken to bring this site to meet the Desired Conditions identified earlier? What partners should we engage into the future for stream restoration? • Wrap-up: In what ways could you or other partners be involved in helping the TNF to achieve 3:00PM Stopdesired 4 (Optional): conditions? Canyon Creek • Drive to Canyon Creek to see an example of a different restoration project. • Discussion: An active restoration project was completed 2 years ago, with passive restoration efforts beginning in YEAR. How has the site matured since then? 2 STREAM RESTORATION FIELD TRIP FOR TNF FOREST PLAN REVISION Information on the Haigler Creek Habitat Project Background Haigler Creek is a perennial tributary of Tonto Creek. The headwaters are located along the Mogollon and Naegelin Rims east of Payson, AZ. The majority of land surrounding the stream is managed by the Tonto National Forest. Two National Forest campgrounds are located along the stream providing loci for recreational fishermen. The low-water crossing below the upstream campground also provides easy access to the stream for fishermen. However, there are several tracks of private land along the stream with limited public access between the two campgrounds. The entire area is serviced by F.R. 200. An assessment survey was conducted in 2009 to provide information about current and potential habitat and geomorphic conditions. This assessment looked at two reaches, the Haigler Creek Campground reach and the Alderwood Campground reach, of Haigler Creek. While most of Haigler Creek provides very good quality habitat, the majority of habitat surrounding both campground reaches is shallow runs that lack depth and cover to hold fish. Additionally, the Alderwood Campground Reach exhibited some stream channel instability due to a split channel which allowed flows below bankfull discharge to follow different channels. Lack to sediment transport capacity in this reach has caused some aggradation of material and stream widening. The purpose of the habitat work at Haigler Creek was to improve fish habitat and stream morphology in heavily utilized reaches of Haigler Creek. Site Description The Haigler Creek Habitat Restoration and Enhancement Project reaches are located on the Tonto National Forest in the vicinity of two popular campgrounds, Haigler Canyon Campground (upper) and Alderwood Campground (lower; Figure 1). In general the reach above the Haigler Creek Campground provide good habitat conditions and no action was needed. This reach provide insight into the habitat potential for Haigler Creek. The reach closest to Haigler Canyon campground had longer runs that provided adequate depth for fish but provided little overhead cover. These areas were improved by increasing the complexity of the stream channel, providing resting and feeding cover for fish. The area around Alderwood Campground contained a long run that also lacked sufficient cover. The channel split just below the run and base flows had migrated from the left channel to the right channel. This area also had a section of eroding stream bank and highly traveled, denuded stream banks. Stabilization of the channel split and revegetation of the denuded banks along with formalized access points improved habitat and angler experience at this site. Purpose The purpose of the project was to enhance and improve aquatic habitat within two sections of Haigler Creek. The first section is located in the vicinity of Haigler Canyon Campground. The second section is adjacent to Alderwood Campground. These actions are necessary due to negative in-stream habitat changes resulting from past recreational use practices. These impacts have contributed to unstable stream banks, continued erosion, increased sedimentation, and decreased heterogeneity of habitat within the creek.

Haigler Creek Aquatic Habitat Enhancement Construction Report DETAILED STRUCTURE DESCRIPTION LOG BARBS Log barbs are structures placed along the outer edges of the stream channel and are used to provide overhanging cover for fish as well as creating stream hydraulics that contribute to maintaining deeper pool pockets downstream of the structures. Logs used for barb structures were obtained on site from dead alder or juniper trees. Each log had a diameter of 12 to 18 inches at the butt end and was around 20 feet long. Barbs were installed along the outside bank of meanders or in deeper sections of the channel where cover was lacking. These structures were cabled to boulder bolsters at one end, which are buried in the bed of the stream. The other end of the log was placed into the bank and boulders were placed on the end of the log to provide ballast. When the barb is located on a section of stream where bank shear stress is high, the upstream end of the log is filled in with rock and gravels to create a solid structure which provides bank protection up and downstream from the structure, and a pool is then dug on the downstream side to provide deeper water habitat (Figure 6 & 7). If the structure is sited in a deeper pool or where bank stability is a lesser concern, there is no fill placed on the upstream side of the structure and the log remains open on the underside, providing overhanging cover (Figure 8).

Natural Channel Design, Inc. 8 May 2017 Flagstaff, Arizona Haigler Creek Aquatic Habitat Enhancement Construction Report BOULDER CLUSTERS Boulder clusters are an assembly of three to four larger rock set into the streambed. Gaps are left between the rocks and provide hiding cover and cause localized scour to maintain deeper areas of water (Figure 9). Figure 9. Boulder clusters provide hiding cover. During installation, the excavator would dig out the bed where the clusters were to be installed, thereby providing a deeper pocket of water around the boulders. LOG OVERHANG A log overhang is a structure that utilizes a log set against a bank in a deeper section of stream and provides overhead hiding cover, similar to an undercut bank. The logs are cabled onto footer rocks and placed against the target bank. A non-woven geotextile is secured to the log and to the bank. This prevents soil from washing down from behind the log. Once the fabric is in place, the gap between the bank and log is filled with rock and soil. This is then planted with wetland plugs.
