Project Need
Need For Project:
Weber County Parks Department is eager to partner with UDWR to improve the aquatic resource at the old Ft. Buenaventura park site. Included in this renovation of particular interest to DWR is a complete drawdown/excavation/bottom sculpting of the old pond. This would enable a creation of a viable fishery resource to be used as an additional community fishery in Ogden. It would function as the centerpiece of the new County Park.
Objectives:
Create a pond with much greater depth than presently available. Create habitat elements for fish and other aquatic life during construction. Excavate and increase capacity of current sediment retention basin and add a second one between the diversion and the pond. Plant aquatic vegetation and add complex habitat elements prior to pond refill.
Project Location/Timing Justification (Why Here? Why Now?):
Pond is very shallow currently non-functional as a fishery. Existing sediment retention basin is nearly full and non-functional. Water is turbid and unappealing to the public. Continued neglect will lead to additional sedimentation.
Relation To Management Plan:
DWR constituency goals. Community Fishery Management plans.
Fire / Fuels:
n/a
Water Quality/Quantity:
Suspended solids are being deposited in the pond and decreasing water volume and appeal to the public. Water heats fast in the summer due to decreased volume. Excavating the sediment from the current pond will increase volume and both quantity and quality of water will be restored.
Compliance:
Previously disturbed site, but high historical significance of this park may require a visit for cultural resource compliance.
Methods:
Diversion will be closed and pond will be dried. Excavators and trucks will haul away sediment and create a bathymetry favorable for aquatic species. Habitat elements, both natural and artificial will be added in strategic locations to benefit both fish and anglers. Shoreline vegetation will be stabilized and access points will be hardened. Existing sediment retention basin will be excavated and an additional one will be constructed. Locations of basins will be such that access will be convenient for maintenance.
Monitoring:
Habitat elements will be periodically monitored to insure effectiveness and maintenance will be completed as necessary. Weber County Parks will monitor sediment levels in retention basins and excavate as necessary.
Partners:
Weber County Parks Department
Future Management:
Periodic excavation of sediment basins will be undertaken by Weber County Parks Department. UDWR will manage the fishery as part of the Community fishery program.
