County briefed on GC Wynne merger and wide-ranging water work: monitoring, Beaver Creek pilot, Grand Lake clarity and wildfire planning

Grand County commissioners heard a multi‑part briefing June 10 on water‑quality governance and ongoing watershed projects, including a proposed merger that will fold the East Grand Water Quality Board into the Grand County Water Information Network (GC Wynne) and progress updates on monitoring, the Beaver Creek restoration pilot, Learning By Doing stream management, Grand Lake adaptive management and a county‑wide wildfire‑ready watersheds planning effort.

Catherine Morris, Grand County water quality manager, and GC Wynne representatives described the merger as an administrative consolidation: East Grand Water Quality Board would formally dissolve and GC Wynne would assume the board’s monitoring, data‑sharing and education functions. Staff recommended transferring the list of entities named in the county’s “10‑41” permit requirement (including Winter Park, Fraser Sanitation entities, Grand County Water & Sanitation District No. 1, Granby Sanitation District and others) to GC Wynne so the permit condition remains satisfied under a single nonprofit steward.

The briefing summarized several active programs:

- Monitoring and outreach: GC Wynne operates an extensive volunteer and staff monitoring program, including approximately 65 temperature loggers at stream sites and regular transparency and phytoplankton checks at Shadow Mountain, Grand Lake and Granby Reservoir. GC Wynne also provides structured environmental education reaching several hundred students per year.

- Beaver Creek pilot restoration: The Kalama/Kawamichi Valley Restoration Collaborative (KVRC) completed a Beaver Creek pilot project this year that installed 29 in‑stream structures, 7 beaver‑dam‑analog features and 31 acres of exclosure fencing to reduce elk and moose browsing. Staff reported early results showing water spreading across the floodplain, encouraging sediment deposition and willow recovery in fenced areas; full woody vegetation recovery likely will take multiple seasons.

- Learning By Doing and Stream Management Plan: The county’s Learning By Doing (LBD) stream‑management plan is in phase two; contractor Ellery Water is developing a river‑health assessment framework that will grade reaches across the cooperative effort area and inform prioritization. LBD is also developing branding and a public website to make the stream plan accessible.

- Grand Lake adaptive management (GLAM): The technical group completed an updated model run for operational scenarios that affect Grand Lake clarity; staff noted model outputs for 2006 and 2022 analog years produced average Secchi (clarity) values in the 2.69–2.97 meter range across runs — within the model margin of error — and cautioned that operational plans must remain flexible as conditions change. Reclamation and other East Slope partners provided updated modeling this year; county and partner representatives will continue to review the draft operational plan for the season.

- Cyanobacteria monitoring and public health: GC Wynne will continue the county’s cyanobacteria monitoring plan at Grand Lake, Shadow Mountain and Granby Reservoir with partners including Northern Water and CDPHE. Staff said measured toxin concentrations in recent years have not approached state recreation advisory thresholds; the county contributes roughly $8,000 annually toward an overall testing budget in the order of $20,000.

- Wildfire‑ready watersheds: The county’s CWCB‑funded wildfire‑ready watersheds project is in the mid‑point review stage. Consultants have completed hydrology and hazard memos and are preparing susceptibility analyses and localized stream assessments; Matrix Design Group’s contract work will inform pre‑disaster planning and mitigation priorities county‑wide.

Commissioners expressed support for the GC Wynne merger to consolidate monitoring and grant capacity, and asked staff to circulate the draft merger agreement to the board and to county counsel for final review. No formal vote to complete the nonprofit merger was taken at the meeting; both entities’ boards will need to adopt the merger agreement to finalize the transfer.
