Need for Project
The east dike of Ogden Bay WMA is the end of Weber River. The east dike essentially holds the river back so that the water can be diverted to North Run, Middle Run, or South Run. Over the years there has been a lot of erosion on this dike. The high run-off years of 2011 and 2017 increased erosion and is contributing to an immediate future failure of this dike. The erosion to this dike is effecting the safety of managers driving this dike. The erosion has impeded into the track of the road in several places making this a safety issue.
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
The objectives of this project will be to rebuild the dike and improve the integrity so that water management can continue the same way well into the future. Large cobble will need to be purchased and delivered to OBWMA. Then the contractor will need to haul it in a dump truck a load at a time and place it appropriately. A track hoe place the cobble as they go. On top of the cobble, we will want dirt fill hauled in and placed on top of the rock to fill up the space. The rock shall be placed as high as the high water mark for erosion prevention. The road shall be expanded 3 feet on top and will be at a 3:1 slope. So there could be 9 feet of cobble extending into the river/ linear foot.
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?)
This dike is THE most important dike at Ogden Bay WMA. This dike makes water management happen on the area. All of the modern infrastructure that was constructed in 2013 will be unusable if the dike fails. If the dike and infrastructure aren't functional, then the wetland can't be managed. A wetland that can't be managed on these "managed" areas, will become unproductive and will likely become inundated with Phragmites.
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
The proposed project meets the objectives in our Habitat management plans. Also the proposed project meets objectives in the WAP such as: Other Ecosystem Modifications Objective #2 for Other Ecosystem Modifications Land management agencies and agents develop vegetation management projects that avoid, minimize, or mitigate impacts to species and habitats identified as vulnerable to these threats such as brush eradication. Habitat modification and loss is being mitigated by perennial plantings, food plots and shrub rows. Objective #1 for Sediment Transport Imbalance Opportunities are found and taken, to modify or remove reservoir infrastructure, or modify outflow management, to simulate or return natural sediment transport. The continual build-up of sediments in GSL wetlands is a major problem that can lead to decreased open water areas, shallower water depths that do not maximize the production of submerged aquatic vegetation, and promotes invasive plant species. The WMA's management relies on channels and water control structures that can be used to help pass through unwanted sediments and maintain a highly diverse and functional wetland. Objective #1 for Droughts Terrestrial SGCNs and key habitats persist on the landscape, despite increasing drought conditions. Drought condition over that past several years has reduced the resilience of highly functional upland habitats. In order to maintain, and rehabilitate these upland habitats, renovation and reseeding is necessary in order to minimize the impacts of drought. Actions that this project will address include; Objective #2 for Droughts Aquatic SGCNs and key habitats persist on the landscape, despite increasing drought conditions. Drought conditions over the past several years has made it imperative that the WMA's have properly functioning water control structures to maximize water deliveries in order to maintain key wetland habitats. Actions that this project will address include; 2.3.6 Restore aquatic habitat complexity 2.3.15 Conduct riparian vegetation treatments to restore characteristic riparian vegetation, and reduce uncharacteristic fuel types and loadings.
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
N/A
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
The water quality along the dike is definitely turbid from all of the erosion that is occurring daily. The quantity of water distributed throughout the WMA will definitely change is this dike fails.
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
This is a maintenance project only. The original footprint of the dike will be re-established, but not exceeded. The UDWR state Archaeologist will be consulted on the project.
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
The waterfowl maintenance crew will do this project next February or March when the water is low. There are several piles of dirt around Ogden Bay WMA that will be used to build up the dike (extend it back out 6-8 feet). The dirt will be hauled, dumped and shaped along the dike. Once the dike is built back up, 2'-4' boulders will be placed on the face of the newly shaped dike up to the high water mark. The boulders will prevent future erosion. Once the dike is rebuilt, the top will be graveled. This should make the dike much more solid than it ever was.
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.
*
Monitoring
The dike will be monitored every time that it is driven.
Describe plans to monitor for project success and achievement of stated objectives. Include details on type of monitoring (vegetation, wildlife, etc.), schedule, assignments and how the results of these monitoring efforts will be reported and/or uploaded to this project page. If needed, upload detailed plans in the "attachments" section.
*

SFW
List any and all partners (agencies, organizations, NGO's, private landowners) that support the proposal and/or have been contacted and included in the planning and design of the proposed project. Describe efforts to gather input and include these agencies, landowners, permitees, sportsman groups, researchers, etc. that may be interested/affected by the proposed project. Partners do not have to provide funding or in-kind services to a project to be listed.
*
Future Management
It will be graded several times each year and will be maintained.
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
This proposed action will allow managers to continue to manage Ogden Bay WMA as it currently is being managed. This will allow continued waterfowl hunting and will allow for the amazing habitat and continued bird use that we are currently experiencing.
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.
