Need for Project
Big Creek currently has populations of Bonneville cutthroat trout (BCT), Brook Trout, and Brown Trout. Randolph Creek, the largest tributary of Big Creek (about 7 miles), has only BCT after UDWR installed a temporary fish barrier and conducted two renovation treatments and BCT reintroduction in 2015. The UDWR desires to complete another piscicide removal of non-native trout and have only BCT present in about 17 additional miles of Big Creek and tributaries. A permanent fish barrier is needed to prevent non-native trout reinvasion following this additional piscicide treatment. The UDWR and the USFWS completed a Northern-region wide environmental assessment (2012) that covers the construction of fish barriers and conducting rotenone treatments, including on Big Creek, that expires after 2018.
Provide evidence about the nature of the problem and the need to address it. Identify the significance of the problem using a variety of data sources. For example, if a habitat restoration project is being proposed to benefit greater sage-grouse, describe the existing plant community characteristics that limit habitat value for greater sage-grouse and identify the changes needed for habitat improvement.

Objectives
1) Topographic survey (GPS) of about 1.5 miles of Big Creek. 2) Develop fish barrier alternatives and work with the landowner, water users, and agencies to select a preferred alternative. 3) Construction design and cost estimates of preferred fish barrier alternative.
Provide an overall goal for the project and then provide clear, specific and measurable objectives (outcomes) to be accomplished by the proposed actions. If possible, tie to one or more of the public benefits UWRI is providing.

Project Location/Timing Justification (Why Here? Why Now?)
Non-native trout outcompete and predate upon native BCT. Many BCT populations have been lost because of non-native trout invasion, competition, and predation. Big Creek has a pure BCT population along with Brook Trout and Brown Trout that have advanced upstream in recent years.
LOCATION: Justify the proposed location of this project over other areas, include publicly scrutinized planning/recovery documents that list this area as a priority, remote sensing modeling that show this area is a good candidate for restoration, wildlife migration information and other data that help justify this project's location.
TIMING: Justify why this project should be implemented at this time. For example, Is the project area at risk of crossing an ecological or other threshold wherein future restoration would become more difficult, cost prohibitive, or even impossible.

Relation to Management Plans
Utah Wildlife Action Plan: The Utah Comprehensive Wildlife Conservation Strategy identifies "species of greatest conservation needs" including BCT [Tier I; Table 5.1 on page 5-3] and several other species that this project will benefit. The plan identifies and describes a series of strategic actions designed to benefit these and other at-risk species and their habitats. Consistent with those strategic actions, this restoration project on Big Creek will address specific high priority threats and conservation actions [Table 6.1 on page 6-41], including (1) "hybridization and competition with non-native species" and (2) "chemically or physically remove non-native salmonids". The work on Big Creek is within a Utah WRI riparian focus area and a WAP Conservation Action Area and benefits mountain riparian habitat, one of the top ten keys habitats in the state as identified in the Utah Wildlife Action Plan. UDWR Strategic Plan: this project will help the UDWR meet its Resource Goal, which is to "expand wildlife populations and conserve sensitive species by protecting and improving wildlife habitat. This project will specifically address objectives 2 and 3 of the UDWR Resource Goal, which are to (1) "increase fish and game populations to meet management plan objectives and expand quality fishing and hunting opportunities," and to (2) "conserve sensitive species to prevent them from becoming listed as threatened or endangered." UDWR Upper Bear River Management Plan (hydrologic unit 16010101): Identifies native and nonnative interactions as a resource and biological issue in this watershed [page 9]. Management strategies for BCT include (1) "chemical treatment of streams or lakes to remove nonnative fish" [page 11]. Bonneville Cutthroat Trout Conservation Agreement and Strategy (signed by all states within historic range): The goal of the BCT CAS is to (1) "ensure the long-term existence of BCT within its historic range [page 2]. Specific actions include (2) the selective control of nonnative species [page 34, sections 4(a,b and c)], as well as (3) subsequent introduction/re-introduction actions [page 35, sections 5(a, b and c). This project will also help to address the specific objective of additional BCT conservation populations in the Bear River in Utah [Table 2].
List management plans where this project will address an objective or strategy in the plan. Describe how the project area overlaps the objective or strategy in the plan and the relevance of the project to the successful implementation of those plans. It is best to provide this information in a list format with the description immediately following the plan objective or strategy.

Fire/Fuels
Not applicable.
If applicable, detail how the proposed project will significantly reduce the risk of fuel loading and/or continuity of hazardous fuels including the use of fire-wise species in re-seeding operations. Describe the value of any features being protected by reducing the risk of fire. Values may include; communities at risk, permanent infrastructure, municipal watersheds, campgrounds, critical wildlife habitat, etc. Include the size of the area where fuels are being reduced and the distance from the feature(s) at risk.
*
Water Quality/Quantity
Not applicable.
Describe how the project has the potential to improve water quality and/or increase water quantity, both over the short and long term. Address run-off, erosion, soil infiltration, and flooding, if applicable.
*
Compliance
NEPA and cultural resource surveys are not required for the survey and design work being proposed on private property.
Description of efforts, both completed and planned, to bring the proposed action into compliance with any and all cultural resource, NEPA, ESA, etc. requirements. If compliance is not required enter "not applicable" and explain why not it is not required.

Methods
An engineering firm will be contracted to conduct the three steps of the fish barrier design process: 1) A high-resolution Global Positioning System topographic survey will be completed on about 1.5 miles of Big Creek that includes two existing irrigation diversion structures. The survey will include the USGS stream gage station that is about 0.25 miles upstream of the upper diversion. By surveying the USGS site and water levels at the time of survey, then the engineering firm will be able to model stream flows very accurately to assist with the development of alternatives and the final design of the preferred fish barrier. Also, fish barrier alternatives will not likely be considered that potentially back water up to and affect the gage site. 2) Develop fish barrier alternatives and work with the landowner, water users, and agencies to select a preferred alternative. Several alternatives will be developed that involve modifying or replacing one or both existing irrigation diversion structures to serve as a permanent fish barrier. Once alternatives are developed, then a meeting among the land owner, water users, and agencies will be held to review the options and select one that would serve both irrigation and fish barrier purposes. 3) Construction design and cost estimates of preferred fish barrier alternative. A complete design to construction detail will be prepared for the selected alternative. The fish barrier will be designed to be stable at the 100-year flow and impassable to fish at a 50-year flow.
Describe the actions, activities, tasks to be implemented as part of the proposed project; how these activities will be carried out, equipment to be used, when, and by whom.

Future Management
Big Creek is currently managed for BCT by UDWR and will remain this way after piscicide treatments are conducted to remove non-native trout.
Detail future methods or techniques (including administrative actions) that will be implemented to help in accomplishing the stated objectives and to insure the long term success/stability of the proposed project. This may include: post-treatment grazing rest and/or management plans/changes, wildlife herd/species management plan changes, ranch plans, conservation easements or other permanent protection plans, resource management plans, forest plans, etc.

Sustainable Uses of Natural Resources
Irrigation of pastures and hay fields for cattle are current uses of the two irrigation diversions that may be part of this project. We will work with the water users to develop alternatives that may benefit irrigation water management. Better water control and application to fields should improve forage production.The proposed Three Creeks grazing allotment consolidation is included in the headwaters of Big Creek. This allotment proposal has the potential to improve riparian conditions and stream shading and reduce sediment; benefits that could extend downstream to the private property where this WRI project is proposed.
Potential for the proposed action to improve quality or quantity of sustainable uses such as grazing, timber harvest, biomass utilization, recreation, etc. Grazing improvements may include actions to improve forage availability and/or distribution of livestock.
