What each level means

Approximate by design — anchored to published thresholds (ramp minimums, full pool, spillway, records) but every cove is different.

At the fuse-plug spillwayabove 6,182 ft
Above 6,182 ft the emergency fuse-plug spillway engages — never approached; the 1997 record was 6,168.06 ft.
Above full pool6,166.4–6,182 ft
Storing into the surcharge space above top of conservation (6,166.4 ft). Reached briefly in big snowmelt years like 1997 and 2011.
Near full6,150–6,166.4 ft
All Jordanelle State Park ramps typically in the water, including the high, single-lane Rock Cliff launch on the upper Provo arm.
First pinch points6,130–6,150 ftnow · 6134.98 ft
Rock Cliff is usually the first ramp out of the water; Hailstone's main ramp stays open. Check the park's weekly ramp report.
Drought territory6,102–6,130 ft
Approaching the post-fill record low (6,102.01 ft, March 2022). Expect long walks to the water and shrinking coves on the arms.
Below the recordbelow 6,102 ft
Uncharted since the reservoir filled in the mid-1990s. Outlet works keep Provo River deliveries running far below here.
