Need for Project
Parowan Pond is a popular community fishery in the small town of Parowan, UT, but it is currently limited by a recent influx of sediment that has reduced the volume of the pond and quality of the fishery. The current state is the result of a poor inflow structure that did not limit or bypass high sediment loads from entering the pond, an issue that was made even worse by the flashy flood events following the Brian Head Fire. The sediment needs to be dredged/removed to regain the full water storage potential of the pond and, subsequently, the full capacity of the fishery. The inflow structure has recently been updated to reduce the sediment supply and minimize future maintenance needs.
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
This project has two main goals with corresponding objectives: Goal 1 - Regain the full capacity of the pond that has been lost in recent years through sediment deposition. Objective - Dredge and remove at least 100 cubic yards of material from around the entire pond. Goal 2 - Minimize future sediment deposition in the pond. Objective - A new inflow structure has been installed that is able to bypass high flow events carrying large amounts of sediment (e.g., extreme monsoon storm).
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?)
There is not a typical threat to the ecological importance of Parowan Pond because it is an artificial water, small in size, and located in an relatively urban setting that is largely unconnected from surrounding habitat and wildlife. However, the fishery in Parowan Pond is important to the angling public and if the capacity is not regained and the pond continues to fill with sediment, the fishery will continue to diminish and may become unable to support a fishery at all. The lower volume of water reduces the total biomass of fish that can be supported and exacerbates habitat issues, especially as related to temperature and oxygen.
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 project meets general Utah Division of Wildlife Resources (UDWR) Goals and Objectives to increase fish populations and expand quality fishing opportunities.
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
The project could help to dampen high temperatures, increase oxygen, and reduce nutrient loading that would lead to eutrophication.
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
Parowan City will ensure any necessary permits/approval/etc. are secured.
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 UDWR will rent a special "long reach" excavator and Parowan City will provide a standard excavator, loaders, dump trucks needed to dredge the pond and install the new inflow structure (Parowan City will also purchase the new inflow structure materials). Parowan City employees will operate the equipment and do the on-the-ground work, likely in the fall of 2021.
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
Periodic site visits will be made to ensure the pond and fishery are functioning. Parowan City will operate and maintain the new inflow structure.
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.
*
Partners
Parowan City
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
The new inflow structure should minimize the future maintenance that is needed (e.g., additional dredging should be needed in decades, not just a few years).
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
Not applicable. The fishery at Parowan Pond is essentially maintained through stocking.
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.
