This use has resulted in numerous stream fords. Stream fords can negatively impact fish directly through damage to incubating eggs and rearing juveniles and disrupting fish migration. Fords cause a loss of fish habitat and can cause increasing bank erosion rates and a loss of water quality through the introduction of fine sediment. This study was conducted to determine the number of stream ford in the Upper Susitna drainage north of the Willow Creek confluence and the upper Peters Creek and Cache Creek drainages. Each crossing was ranked on a scale of 0 to 5 based on the degree of changes to stream channel characteristics and potential for sediment input. There were 158 crossing identified, 49% of these on streams supporting salmon. Forty two percent of the crossings were ranked with site scores of 4 or 5. Key words: All-terrain-vehicles (ATV), sediment, stream fords, off-road-vehicles (ORV), Susitna River, Matanuska-Susitna Borough, Alaska. INTRODUCTION The use of all-terrain vehicles (ATV) has been increasing over the past 10 years. These vehicles are used to access remote property, for hunting and fishing, and for recreation. ATV trails often follow historic trails, winter routes, seismic lines, and electrical transmission lines. ATV trail use, however, has the potential to negatively alter wetland and stream habitats directly and indirectly affecting fish and fish habitat. Direct impacts can occur through damage to spawning redds, disruption of migration and spawning, and direct injury. Indirect impacts can be through changes in water storage and runoff timing, loss of nearshore habitats, migration barriers, and water quality. Information on trail locations, density, and relative impacts are needed to assess impacts to fish habitat and develop recommendations for alternatives to minimize or avoid habitat losses. This study was conducted to begin this process by locating ATV stream crossing locations and evaluate relative fish and fish habitat impacts. METHODS The study area included tributaries to the upper Susitna River. These included Willow Creek north to the Talkeetna River on the east side of the Susitna and the Rabideau, Trapper, Kroto, Peters, and Cache Creek drainages on the west. Surveys were conducted in October of 2001 and June of 2002. ATV crossing were located by flying over the stream drainages in a Helicopter. The latitude and longitude of the locations was recorded using the global positioning system (GPS) and a handheld receiver (Garmin 12XL) and entered on field data sheets. In October, digital videos (Sony TRV 900) were taken of the crossing locations. In June, locations were photographed using digital (Nikon Coolpics 9000) and 35 mm Nikon camera. A Site Score was generated at each site by summing positive site impact parameters ranging from 0 to 5 (Wiedmer 2002). Site impact parameters included the following (Figure 1). Exposed Soil—Visible mineral soil beneath the trail adjacent to the stream. Denuded Banks—All of the vegetation removed from the trail on both banks. Increased Width—Stream width two times greater than natural channel. Surface Erosion—Water pooled or running on the trail surface or evidence of past erosion. 2 Figure 1. Examples of ATV crossings. Numbers are crossing site scores. 3 Bank Alteration—Topography of stream banks altered. Site scores and photographs were used to create the Arcview project (version 3.2) accompanying this report. The photographs are stored on the computer disc with the Arcview project and are stored by site number. The Atlas to the Catalog of Waters Important for the Spawning, Rearing or Migration of Anadromous Fish (ADF&G 1998) was used to determine whether crossings were on specified waterbodies. RESULTS & DISCUSSION A total of 158 stream crossing sites were located within the sample area. The stream crossing locations are shown in Figure 2 through Figure 6. The location and parameter data for each crossing is given in Table 1. The location, ranking data, and photographs are projected on an Arcview project (version 3.2) recorded on the accompanying compact disc. Alternatively, photographs for each site identified on the maps or table can be viewed directly. The photographs on the compact disc have the same name as the crossing location. We found the use of conventional 35 mm camera to produce the best photographs. The digital video created large files that were difficult to manipulate. Also, the quality of still photographs taken from the digital video was poor. The quality of digital photographs was better; however, images were often blurred or missed. Shutter speeds with the digital camera were slow causing blurred photographs when light levels were low. Also the response time (time from when the exposure button was pushed until the exposure taken) was slow often causing repeated attempts to photograph a site. Seventy-eight crossings (49%) were located on specified anadromous waters. Forty-two percent of all crossings were ranked at site scores of 4 or 5. The portion ranked 4 or 5 was the same when evaluating all of the sites or just the anadromous fish streams. Among the scoring criteria, 83% of the sites had exposed soil. This supports our observation that the vegetation on ATV trails is removed after only limited use. This condition suggests that potential impacts to water quality through the introduction of fine sediment occurs early and often in the development of ATV trails. Following exposed soil, bank erosion is the next most common condition observed (63% of the sites). On the west side of the Susitna River most of the crossings area associated with major developed trails (Figure 3). Sites 100 through 115 are located on the extension of Oilwell Road off of Petersville Road. This trail is used primarily to access mines and recreational land. Sites 117 through 126 are located on the trail that runs from Shulin Lake north along Peters Creek to the Petersville Road. Sites 141 through 145 are on the Collinsville Trail near the Three Forks Roadhouse. The approximate location of this trail is shown on the U.S. Geological Survey maps (1:43,000). There may be additional stream crossings on this trail that we did not survey during this project due to weather. Sites 146 through 160 are located on the mining roads of the upper Peters Creek and Cache Creek drainages. Sites 77 through 86 were crossing tributaries to Rabideaux Creek and seemed to be associated with the “Winter Trail” identified on U.S. Geological Survey maps. Trails is this area likely are limited by extensive wetlands. The remaining stream crossings west of the Susitna were associated with trails leading to or around recreational cabin, accessed from either the Parks Highway or Petersville 4 Road. At some locations homeowner associations have formed and constructed ATV bridges at previous ford locations (Figure 7). Crossings on the east side of the Susitna River were not so clearly identified with trails. Sites 75 and 76 are on the Clear Creek Trail, and sites 72 and 73 are on the trail to Larsen Creek. Many of the ATV crossings in the Upper Answer Creek drainage are along the intrastate transmission line. There are a number of crossings located at the bridge where Yoder Road crosses Montana Creek. Most of these crossings appear to be due to recreational ATV riding. Most of the additional crossings in the Montana Creek drainage are where the Middle and South Fork trails cross tributary streams. Sites 25 through 30 are crossings of the North Fork of the Kashwitna and tributary streams. There is what appears to be a hunting trail that travels east along the N.F. of the Kashwitna River. There are a number of crossings of the upper end of Little Willow Creek (sites 35 through 40). Four out of the six of these crossings are ranked either 4 or 5. This portion of Little Willow Creek currently is not specified as a salmon stream; however, recent surveys have identified that area as salmon habitat. These crossings are located on a trail from the Hatcher Pass road east of Willow Mountain. Crossings 49 through 52 cross a tributary to Willow Creek and are located on the Willow Mountain trail. SUMMARY Many of the 160 stream crossings identified in this study are located on well-developed trails. This is particularly true on the west side of the Susitna River. Constructing bridges at these crossing locations, and conducting other trail improvement project on these trails could reduce potential water quality and fish habitat impacts. Although not as clear, crossings east of the Susitna River also appear to be associated with major trails. Additional work needs to be conducted to determine trail location and use. Once locations and potential environmental impacts of trails are known, possible solutions could be investigated such as closing redundant trails, rerouting trails, and building crossing structures. 5 Figure 2.

The Alaska Habitat and Restoration Division has released two PDF versions of this report. The first PDF version lacked pages numbered 15 and 16, but Table 1 appeared correctly formatted on pages 10-13. The "Literature cited" page appeared duplicated with a black-and-white photo as page 14 and with a colored photo as page 17. A second PDF version was also released with better textual formatting, proper page numbering, and without the duplicated "Literature cited" page. However, the columns and rows in Table 1 (on pages 10-16) were out of alignment. This PDF file comprises chiefly the second PDF version, but pages 10-16 with the poorly formatted table were replaced by pages 10-13 in the first PDF. For that reason, this PDF that ARLIS has made available does not have pages 14-16. 17 Figure 7. ATV crossing of Trapper Creek at site 130 showing newly constructed bridge in upper right corner.
