Summary

Whetstone Creek is a tributary of the that flows through agricultural, industrial, and rural residential land, and drains the Whetstone Industrial Park and urbanized areas of White City before meeting the Rogue River at river mile 128.5. The creek, which drains a 13,400-acre (21 sq. miles) watershed, flows through ecologically valuable tracts of land such as the Oregon Department of Fish and Wildlife’s (ODFW) Denman Wildlife Management Area and the Agate Desert (Figure 1). The lower five miles of Whetstone Creek have been identified as a candidate for habitat restoration by ODFW and the Bear Creek Watershed Council. The creek is naturally intermittent; however, it conveys irrigation flows in the summer (making it “perennial” in its current state). Whetstone Creek, although currently suffering from degraded habitat and water quality conditions, has excellent restoration potential because of its relatively underdeveloped floodplain.

Conditions and Problems

Whetstone Creek and Swanson Creek, a tributary of Whetstone Creek, while accessible to anadromous salmonids, have limited fish passage and riparian habitat due to 1) past land use practices, 2) invasive plant species, 3) road crossings, and 4) channelization.

1) The presence of native riparian vegetation (such as alder, cottonwood, and mountain-ash) has been reduced or eliminated from several areas of the creek corridor, 2) Reed canarygrass (RCG) has invaded the corridor to an extent that the RCG has altered the channel and created passage obstacles for migrating native fish above the confluence of Whetstone Creek and Swanson Creek (approximately Whetstone Creek Mile 2.5) See Figure 2. 3) Culverts and road crossings on lower Whetstone Creek at Highbanks Road, Kirtland Road and the railroad trestle, and on Whetstone Creek and Swanson Creek at Table Rock Road have constrained the channels of Whetstone and Swanson Creeks from multi-thread “braided” channels to single channels. While these culverts and crossings are not absolute barriers to fish passage, they do not meet current passage standards, and although the single channels may help with fish passage during late spring, summer, and fall, the constrictions limit the ability of the creek to provide low velocity habitats for overwintering fishes, especially during high flow events after storms. Some of these road crossings are due for replacement, e.g., Table Rock Road is planned to be widened over the next several years. 4) Historically Whetstone Creek had a wide, multi-channel drainage pattern that has been channelized through much of the watershed.

Whetstone Creek is in the center of a unique type of valley prairie – a large grave alluvial plain known as the Agate Desert. Government Land Office (GLO) surveys were conducted in the area in 1854-1855. An early brochure described the area as, “Near the center of the valley is a tract about six miles square called The Desert… It is covered with grass in the early spring, but otherwise is destitute of vegetation” (Anonymous 1885). GLO surveyors found mounded prairie interspersed with narrow scabland (swales, vernal pools) covering several thousand acres. The mounded prairie rests on a compacted gravel hardpan which creates a perched water table. This hardpan could explain the shallow, braided character of Whetstone Creek. Surveyors did note a few scattered white oak trees on this prairie, clumps of chaparral (Ceanothus), and riparian forest near the Rogue River.

Use by spawning fish was likely limited to summer steelhead in the intermittent conditions that were present in the Whetstone Creek watershed historically. According to ODFW, Whetstone is also used as winter habitat by juvenile steelhead and coho salmon. Juvenile spring Chinook are also likely to use the downstream reaches of Whetstone Creek in the winter. Fish sampling by ODFW found juvenile steelhead (3 individuals) below the confluence of Swanson Creek in August 2000 and Coho salmon (39) and steelhead (39) during March 2006. Sampling conducted in Whetstone Creek in 2010 above Table Rock Road by ODFW found no native salmonids (Personal communication, Dan Van Dyke, ODFW District Fish Biologist, 2010). Exotic fish species are also present, including gambusia, bluegill, and redside shiners.

Watershed Characteristics

Whetstone Creek from the mouth to Whetstone Pond on the Denman Wildlife Management Area (Figure 2) is comprised of four distinct reaches described below. The creek continues upstream past Denman all the way to the north side of Roxy Ann Peak, and contains approximately 30 miles of stream channels, including tributaries. This assessment primarily addresses only the lower five miles of the creek.

Reach 1 – mouth to Highbanks Road: • Approximately 4,900 feet long. • Lower Whetstone Creek (Reach 1) is characterized by runs, riffles, glides, and pools with areas of intact, healthy riparian vegetation, but high potential for restoration in the majority of the reach. • Pools near the mouth in the lower 1,000 feet of the creek are created by large instream wood. • The next section of the reach upstream of the lowest 1,000 feet, which is approximately 1,900 feet long, lies within dikes on both banks. The creek is squeezed in between two former gravel extraction mines, now wildlife ponds. This section has long, narrow low-gradient pools and riffles. • The floodplain is extremely wide near the mouth as the creek joins the Rogue River (approx. 700 feet), is narrow in the diked section (100-200 feet), and becomes fairly wide again in the upper 2,000 feet downstream of Highbanks Road, ranging from 150-400 feet in this section. • Floodplain connection ranges from good in the lower 1,000 feet, to poor in the diked section, to moderate in the upstream section. • A decrepit culvert in the center of the diked section, which had become a flow and passage obstacle in the lower portion of this reach, was removed in summer 2011.

Reach 1 – mouth to Highbanks Road

Reach 2 – Highbanks Road to Kirtland Road: • Approximately 3,800 feet long. • Reach 2 has less channel complexity than Reach 1. The channel is wider and shallower with less riparian vegetation, and the pools that exist are primarily topographic in nature, with a scarcity of large wood instream. There is one large pool immediately downstream of the Kirtland Road bridge. • The floodplain ranges from 500 feet wide near Highbanks Road to 700 feet wide downstream of Kirtland Road. • Floodplain connection is medium throughout the reach because of channelization. • Reach 2 has high potential for restoration in the majority of the reach. • Knife River is conducting a 10-acre mitigation project along a 2,000 foot stretch of Reach 2 immediately downstream of Kirtland Road. Objectives of this mitigation project are to remove the reed canarygrass (RCG) colony, and other invasive weeds, restore riparian vegetation along the stream corridor, and re- establish the historical floodplain connectivity of the site. The creek in this reach was severely channelized, so to allow the stream access to the floodplain and to

Rogue Valley Council of Governments 6 Whetstone Creek Fish Passage and Riparian Conditions Report remove the RCG rhizomes, the top layer of soil (approximately 1 foot) was removed from the riparian area. Then the riparian area was planted with native trees, shrubs and forbs. This project will be instructive as attempts are made to eradicate or reduce the impacts of RCG and restore natural hydrologic function throughout the creek, but particularly in the area of heaviest RCG infestation in Reaches 3 and 4.

Reach 2 – Highbanks Road to Kirtland Road

Rogue Valley Council of Governments 7 Whetstone Creek Fish Passage and Riparian Conditions Report

Reach 3 – Kirtland Road to Table Rock Road: • Approximately 11,000 feet long. • The lower part of Reach 3 has a healthy oak/mountain-ash/alder community within the floodplain that can serve as a reference site and an anchor point for future restoration work. • The lower stretch is characterized by runs, riffles, glides, and pools with areas of intact, healthy riparian vegetation, but medium potential for restoration in the majority of the reach. The upper stretch of Reach 3 has high potential for restoration due to the severe RCG infestation, and lack of pools, riffles and open water. • Pools in the lower reach are largely created through topography, but instream wood has contributed to the stability of a small number of the pools. Pools are also created by the railroad trestle, small agricultural access bridge in the center of reach, and by the Table Rock culvert at the upstream end of the reach. • The floodplain ranges from 300 feet wide upstream of Kirtland Road and in the center of the reach near the City of Medford wetland mitigation site, to 800 feet near Amy’s Kitchen and the RCG area downstream of Table Rock Road. • The Whetstone Industrial Park Overlay (Section 7.3.2; ASC 82-1) of the Jackson County Land Development Ordinance was adopted in 2009. The minimum lot size in the industrial park is 20 acres, and it contains several large industrial developments including Amy’s Kitchen, Pacific Crest Transformers, Linde Electronics and Specialty Gases, and Erickson Air-Crane. • Floodplain connectivity is good throughout this reach. • Reach 3 has more stream channel complexity than Reach 2 due to less channelization. This area also has three recent completed mitigation projects (Figure 4) that included riparian planting and some stream channel work: o RVS – vernal pool restoration and native planting upstream of Kirtland Road to mitigate for sewer pipeline construction in vernal pools and the stream channel area. o Amy’s Kitchen – vernal pool and floodplain reconstruction as mitigation for vernal pool impacts and stream impacts due to factory construction. o City of Medford – 5.5 acre wetland mitigation for Crater Lake Avenue realignment at Coker Butte Road. • Much of Reach 3 has been intensively grazed for decades. Many of the areas with grazing have poor riparian forest development or simplified riparian habitats / structure, i.e., grasses, sedges, rushes, and few shrubs and trees.

Reach 3 – Kirtland Road to Table Rock Road

Rogue Valley Council of Governments 9 Whetstone Creek Fish Passage and Riparian Conditions Report

Reach 4 – Table Rock Road to Denman Pond: • Conditions in Reach 4 are very similar to those in the upper stretch of Reach 3 – low-gradient stream dominated by reed canarygrass wetlands.

General Observations • Numerous irrigation canals and drainage channels criss-cross the upper portion of the watershed above Highway 62, which contributes to summer flows in Whetstone and Swanson Creeks. The amount or percentage of total flow is uncertain, but it is likely that irrigation return flow comprises the majority of the flow in late summer. Irrigation flow may contribute to unnaturally high water levels in area ponds, e.g., the pond near Agate Road and Leigh Way. Whetstone Creek also receives significant wet weather stormwater flow from the urbanized portions of the watershed, i.e., White City.

Restoration Opportunities

ODFW’s assessment and 2010 priorities include lower Whetstone Creek as a moderate priority, made higher by the presence of public land in the western interior valley reach, including the Whetstone watershed. A large percentage of the land in the lower Whetstone drainage is publicly owned: the Hall Tract Unit of the Denman Wildlife

Rogue Valley Council of Governments 10 Whetstone Creek Fish Passage and Riparian Conditions Report

Management Area comprises approximately 500 acres, and the City of Medford-owned land in the Whetstone Industrial Park equals approximately 750 acres. This area is part of the North Medford Conservation Opportunity Area identified in the Oregon Conservation Strategy. ODFW’s assessment mentions: • Fish passage: Significant barriers at stream/road crossings are suspected but not quantified at this time. The crossings at Kirtland Road and Table Rock Road are not absolute barriers to fish passage. An extensive reach of reed canarygrass may pose a barrier to fish passage, however. A possible treatment scenario to restore a fish passage channel through the RCG has been received by ODFW (Geomorphologist Janine Castro memo, USFWS, 2008): Ms. Castro noted that Whetstone Creek has many opportunities for riparian restoration and fish usage. The area is dominated by reed canarygrass (RCG), which is limiting natural riparian recovery and aquatic habitat diversity. Since the area is large and efforts to remove the RCG entirely would likely fail, alternatives must be considered to provide fish passage and to establish enclaves of native riparian species

Ms. Castro recommended that the following actions be taken: ▪ Create a deep, narrow channel to improve fish passage and usage. Channel depth should not exceed maximum channel depth within the reach, but the channel should be deep enough to prohibit grass establishment in the bed of the channel. This should be undertaken as a pilot project in an easily accessible area to allow for on-going monitoring and evaluation for additional work. ▪ Remove small patches of RCG and subsequent planting of native vegetation. These patches will be easier to maintain than dispersed plantings and will provide a seed source for natural propagation if a larger-scale restoration project is undertaken. ▪ Refer to the Reed Canarygrass Working Group for further details about RCG management (http://www.ser.org/sernw/rcg_info.asp).

Additional restoration opportunities include a wide range of instream, streambank, and upland treatments: • Riparian restoration: Opportunities for riparian restoration are prevalent in various locations throughout the sub-basin, including the Denman Wildlife Area. Benefits for summer stream temperatures from riparian restoration will be limited to the lower portion of the sub-basin where irrigation flow conveyance comprises the majority of stream flow in summer. Riparian restoration within the winter distribution range of juvenile salmon and steelhead should encourage beaver activity which would improve winter rearing conditions. Riparian restoration will also benefit a wide variety of wildlife species. • Increased sinuosity: Historical photos of Whetstone Creek show significant sinuosity and complexity, but the stream has been channelized and simplified through much of its length. Sinuosity encourages surface flows to percolate through gravel

bars and emerge downstream as cooler water. These pockets of cool water are used extensively in small and large streams as habitat for native fishes to remain cool in water with higher oxygen content, and survive high water temperatures in July and August. • Increased Recreational Opportunities: The Mace property near the mouth of Whetstone Creek is slated for development as a recreation hub following gravel extraction from the 200-acre site in the next few years. The Mace property, formerly owned by the late Bob Mace, is now managed under a trust established by Bob and Phyllis Mace to set aside royalties from the gravel mining to support “watchable wildlife” projects. ODFW is planning to create a pond that will be used for flat water recreation and warm water fishing, hiking, possibly camping, and other recreation pursuits. There is recreational value in connecting this amenity with trails to the Denman Wildlife Management Area for hiking, birding, wildlife viewing, horseback riding and other opportunities. • Additional surveys: ODFW plans additional surveys for fish presence upstream of the reed canarygrass reach of Whetstone Creek and in Swanson Creek upstream from Highway 62. RVCOG coordinated additional water quality surveys in summer 2012 with interns from Southern Oregon University (see Attachment 2).

ODFW observations, March 17, 2011

As clearly indicated by the summary above, the proposed restoration recommendations listed at the end of this report are closely aligned with the following ODFW assessment.

Use by spawning fish was likely limited to summer steelhead in the intermittent conditions that were present in Whetstone Creek historically. Whetstone is also used as winter habitat by juvenile steelhead and coho salmon. Summer presence of juvenile steelhead was observed by ODFW (8/17/2000). Exotic fish species are present, including gambusia, bluegill, and redside shiners.

Western pond turtles are present, and evidence of successful reproduction has been observed. Native crayfish are present, along with two exotic crayfish species. Bullfrogs and tadpoles are known to be present.

An annual habitat survey is conducted by ODFW’s Aquatic Inventory Project on approximately 500 meters of Whetstone Creek just below Swanson Creek.

Current documented distribution of native fish Juvenile steelhead have been found in Whetstone Creek up to Swanson Creek (roughly stream mile 3.3, and in Swanson Creek just upstream of Highway 62 (roughly stream mile 3.5).

Summary of Recommended Restoration Priorities

1. Add fencing where appropriate in the floodplain and riparian area from Kirtland Road to the mouth. Priority areas for fencing include riparian areas that are currently grazed adjacent to areas with an established tree canopy, and riparian areas that will be planted. Approximately 6,000 feet of fencing is needed upstream of Highbanks Road, and another 4,000 feet downstream of Highbanks. This will help establish riparian forest conditions leading to a more stable streambank, habitat complexity, and water quality improvements. Fencing would include watering facilities for cattle if needed, whether off-stream or on-stream, and would consider the use of cattle grazing as a management tool (“flash grazing”), but only after new riparian plantings are well-established. Fencing would not be placed in areas that will be mined for aggregate, i.e., fencing will be placed between the stream and the aggregate zoned areas.

2. Plant the area downstream of Kirtland Road between the Knife River mitigation project and Highbanks Road. Additional planting will be implemented downstream of Highbanks Road to the diked reach at approximately river mile 0.5. This planting will reestablish a riparian tree canopy, riparian shrubs and forbs that will increase the stability of the stream channel and stream habitat complexity, and improve water quality.

3. Remove the dike at river mile 0.5 to allow the stream to reclaim the floodplain in this reach.

4. Add instream complexity, primarily large wood, to the reach below Highbanks Road to create better fish habitat and spawning conditions – deeper pools and gravel retention.

5. Develop strategy for control of reed canarygrass (RCG) in Whetstone Creek. Focus on the area above the confluence with Swanson Creek, downstream of Denman Pond. Measures to control RCG will include: a. Reestablishing a more-defined stream channel through the RCG morass to alter hydrology of the floodplain and establish drier conditions in areas dominated by RCG, thus allowing native plants to outcompete RCG. b. Removal of RCG and its rhizomes to prevent immediate resprouting. Removal will only be done in limited plots of ten 100 ft2 sized swaths (total of 10,000 ft2) near the stream to determine the success of various methods of eradication and replanting. Methods for removal include scraping off the top soil and replacing, burning/steaming the RCG, repeated mowing, and herbicide application. c. Restore native wetland vegetation, including riparian canopy component (mountain-ash, alder, willow), in areas where RCG has been removed. Another alternative treatment would be the placement of sod mats containing native

Rogue Valley Council of Governments 14 Whetstone Creek Fish Passage and Riparian Conditions Report

grasses and forbs. These mats would be grown in local nurseries. The J. Herbert Stone USFS Nursery has supplied these mats for wetland restoration projects, or private nurseries could grow the mats. The sod mats would need to be dense enough the prevent RCG seed from becoming established on top of the mat. The mats would be held in place with willow stakes. d. Maintain native plantings to allow them to become established above the height of re-emerging RCG. As native plants grow, they will shade out the RCG, and create higher quality habitat and stream conditions.

6. Work with ODOT and Jackson County to improve passage for fish and wildlife where Kirtland Road (ODOT) crosses Whetstone Creek, and Table Rock Road (Jackson Co.) crosses Whetstone and Swanson Creeks.

7. Establish trail system near creek connecting Denman Wildlife Management Area to Rogue River and future Mace Pond/ODFW project. Establishment of the trail will increase the visibility of Whetstone Creek to the public, which will lead to increased stewardship. The trail will also allow the public to view high quality vernal pool areas, and gain appreciation for these resources.

8. Establish baseline conditions for the lower five miles of Whetstone Creek, and fill data gaps including: quantifying the influence of urban stormwater runoff on winter flows and water quality; quantifying irrigation runoff on summer flows, water temperatures and general water quality conditions; additional LiDAR data for the downstream reach below Kirtland Road and the reed canarygrass-infested areas; and additional information on fish usage. RVCOG’s site visits, additional ODFW surveys, SOU water quality monitoring data, and the past floodplain studies (City of Medford, Knife River) can serve as a basis for data gathering and analysis.
