Mitigation commission updates Utah County on Provo River Delta restoration, land transfers and trail changes

The Utah Reclamation Mitigation and Conservation Commission and project staff updated the Utah County Board of County Commissioners on plans to convert roughly 260 acres at the mouth of the Lower Provo River into a restored delta and wetland complex intended to aid recovery of the June sucker, a fish species found only in Utah Lake.

Mark Holden, director for the Mitigation Commission, and Melissa Stamm, the project’s lead coordinator, said the project would divert most of the Provo River’s lower flow north into a constructed channel and lower the north half of the Skipper Bay Dike so the lake can reoccupy portions of its historic shoreline. Stamm said the work is designed to create nursery and rearing wetland habitat that currently is missing from the lower river channel and that the Delta is a key element of the June Sucker Recovery Program.

The presentation emphasized the multi‑agency nature of the work. Holden described two near‑term agreements: an overarching implementation agreement that would define roles among signatories including the Mitigation Commission, Department of the Interior, Central Utah Water Conservancy District, Utah County, Provo City and state natural‑resource divisions; and a land‑transfer and management agreement that would transfer Delta lands to the state for administration by the Division of Wildlife Resources while conveying recreational facilities, easements and ownership arrangements to Utah County for long‑term operation and maintenance.

Stamm and Holden listed planned public amenities — a berm trail, a viewing tower, a trailhead and fishing platforms — and said the commission intends to fund construction and then deed or easement portions of the facilities to Utah County, which would assume maintenance responsibilities. Holden noted that a small portion of the existing Skipper Bay Dike trail (purchased in part with Land and Water Conservation Fund money) will be removed, replaced and reconnected to produce a net half‑mile increase in county trail mileage, but warned that LWCF requirements mean the county and the project must follow a state coordinator’s process to ensure no net loss to the public.

Commissioners pressed for details about long‑term operations and maintenance costs and lifecycle expectations for facilities and pavement. Holden said project staff have coordinated repeatedly with county staff and aim to minimize custom equipment that would drive higher O&M costs and to obtain county approval of final designs. The Mitigation Commission also noted a funding agreement for additional mosquito monitoring tied to the project.

Holden invited commissioners to public site tours (held on second Saturdays each month) and said the agency expects to release a draft environmental assessment this fall addressing the Utah Lake Wetlands Preserve and property transfers to the state. Construction began the prior spring, and presenters said the project is planned to be complete and open to the public in 2024, assuming anticipated schedules and approvals hold.

The work session concluded with technical questions about June sucker culture and stocking: staff said state hatcheries are raising larger (12‑inch) juvenile June sucker for stocking — in recent years about 20,000–25,000 12‑inch fish were reported being grown — and that the Delta is intended to improve natural juvenile recruitment so long‑term reliance on hatchery production diminishes.

Next steps identified by staff included renewed coordination sessions with county staff to finalize easements, refine recreation designs and negotiate the implementation and land‑transfer agreements.
