Great Basin Pulse

Reno–Tahoe basin

What does this year’s snow mean for a fish a hundred miles away?

Snowpack

Every drop starts here. Sierra snow sits on these ridges for months, then leaves the mountains the slow way — melt, not flood — the pulse that keeps the Truckee running after winter is gone.

The lake

Lake Tahoe is a reservoir with a legal ceiling: about 6,229 feet. A dam at Tahoe City lets water out under the Truckee River Operating Agreement. What leaves the lake is this river.

Right now the surface sits at 6,227.34 feet (U.S. Bureau of Reclamation datum) — 1.76 feet under the legal ceiling.

The outlet is running 276 cubic feet each second — Tahoe spilling into the Truckee.

The river

The Truckee leaves Tahoe City, cuts through the canyon, and crosses Reno. Same water. Two gauges.

At Reno the river is moving 378 cubic feet past the gauge every second — a late-summer pulse, not the spring rise a spawning fish would need.

The terminus

The river does not reach the ocean. It ends at Pyramid Lake. The cui-ui lives in exactly one place on Earth — this lake — and every spring it waits at the river mouth for flow high enough to swim upstream and spawn.

Pyramid Lake's surface is at 3,802.04 feet right now.

The air

The same basin traps smoke. At night a temperature inversion settles over the Truckee Meadows; wildfire haze builds until daytime wind flushes the valley.

Reno is 56°F right now.

Right now the Reno reporting area sits at AQI 54 — moderate, driven by PM2.5.

The ground

Reno sits in active country. The Nevada Seismological Laboratory at UNR runs the statewide network; as of this year Nevada's data still helps power California's ShakeAlert, while Nevada waits on its own alerts.

The most recent event in this week's catalog is M 2.4 — 9 km NW of Honey Lake, CA.
