Great Basin Restoration Project
The Great Salt Lake is dying — and it's taking the Intermountain West's climate engine with it. The engineering is proven. The cost is a rounding error against the catastrophe of inaction. The only thing missing is will.
Measured against 1980s baseline. The lake has lost over two-thirds of its volume in four decades.

Full pipeline and restoration system. A fraction of the economic cost of collapse.
From federal authorization to measurable lake recovery. The infrastructure exists. The will doesn't — yet.
Real-time Snake River flow from USGS stream gauges, Idaho snowpack from NRCS SNOTEL stations, and live Great Salt Lake elevation — the actual field conditions that determine pipeline viability today.
The Great Salt Lake was once the second largest salt lake on earth. At its historic peak, it covered over 3,300 square miles and sat at an elevation of 4,212 feet. Today it barely covers 1,000 square miles, sitting over 20 feet below that mark. It is in freefall.
What's dying isn't just a lake — it's a regional climate system. For generations the lake acted as a thermodynamic engine, supercharging passing storm systems with evaporated moisture, amplifying snowpack across the Wasatch and Uinta ranges, and sustaining the precipitation cycles that the entire region depends on.
As the lake shrinks, it pumps less moisture into the atmosphere. Storms weaken. Snowpack diminishes. The rivers that feed agriculture and cities carry less water — and less water reaches the lake, accelerating the spiral.
The exposed lakebed is not benign. Decades of agricultural runoff have concentrated arsenic, mercury, and heavy metals in the sediment. When the lake retreats, the wind picks this up and carries it into Salt Lake City, into lungs, into soil.
The Great Salt Lake wasn't merely scenic infrastructure. It was a thermodynamic amplifier embedded in the Intermountain West's climate system — and its collapse is restructuring regional weather patterns in ways that compound with every passing year.
Cold air masses moving over the warm, saline lake surface absorbed enormous quantities of water vapor, condensing into lake-effect snow over the Wasatch Range. This mechanism delivered up to 30% of regional snowpack in peak years. With the lake surface reduced by over 70%, this moisture engine has been catastrophically downgraded.
As the lake shrinks, regional humidity drops, increasing evapotranspiration stress on surrounding vegetation, reducing cloud formation probability, and weakening convective precipitation patterns. Less lake surface means less moisture recycled into the system — a feedback spiral that tightens each year the lake remains at critically low levels.
The 800+ square miles of newly exposed lakebed contain concentrated heavy metals from decades of agricultural runoff. Wind events mobilize this sediment into the Wasatch Front air corridor. Salt Lake City already records some of the worst air quality days in the nation on high-wind events — and the exposed lakebed is expanding annually.
The GBRP proposes a 380-mile pressurized pipeline corridor from the Snake River system in Idaho to the Great Salt Lake — following the I-84 right-of-way through proven terrain, using HDPE pipe at 96-inch dual-bore configuration.
The Snake River carries surplus water that currently flows into the Pacific. With appropriate water rights agreements and seasonal surplus management, a 90-day annual pulse cycle can deliver meaningful restoration volume without disrupting downstream agricultural uses.
The pipeline doesn't just move water — it's a dual-use energy corridor. Solar installations along the I-84 ROW generate power that offsets pump energy costs, creating a system that is net-grid-positive at flow rates below 24 m³/s.
This is not speculative infrastructure. The route exists. The pipe technology exists. The solar capacity can be calculated to the kilowatt. The physics has been run.

The 563-kilometer I-84 corridor isn't just a pipe route — it's a linear energy asset. Solar installations along the existing right-of-way, operating at conservative 25% capacity factor with partial shading accounted, generate enough power to flip the thermodynamic ledger from net-deficit to net-positive.
At the Phase 1 recommended flow rate of 10–15 m³/s, the system doesn't just move water — it feeds the grid while doing it. Best-case net grid contribution at Q=10: +245 MW. Worst-case: +205 MW. Both positive. Both conservative.
This is the argument that reframes GBRP from a conservation expense to a federal infrastructure investment with measurable return. The lake restoration is the mission. The energy corridor is how you fund it politically.
The cost of inaction includes regional agricultural failure, municipal water crisis, toxic dust health costs, ski industry collapse, mineral extraction loss, and climate cascade across the entire Intermountain West. The pipeline isn't expensive. The alternative is.
The 90-day pulse model is strategically superior to continuous operation for Phase 1 on three dimensions. First, it minimizes Snake River draw during critical agricultural windows while delivering meaningful restoration volume. Second, it's easier to permit — a seasonal diversion is a fundamentally different regulatory conversation than a permanent one. Third, it generates observable lake response data within a single annual cycle.
The Q = 10–15 m³/s operating range keeps velocity below 2 m/s, eliminating surge risk, maintaining manageable friction losses, and staying squarely in net-grid-positive territory in all scenarios. This is not the most aggressive the system can run — it's the most defensible position from which to prove the concept and then scale.
Once Phase 1 demonstrates measurable lake elevation response, the political calculus changes. You are no longer asking for faith. You are presenting results.
Saving the Great Salt Lake is not a conservation project. It is regional climate infrastructure maintenance.
Restoring lake surface area reactivates the lake-effect moisture engine that historically boosted Wasatch snowpack. Ski industry, municipal water supply, and downstream agriculture all depend on this cycle.
Re-flooding exposed lakebed locks down arsenic, mercury, and heavy metal sediment. Every acre-foot delivered directly reduces the surface area available for wind mobilization into the Wasatch Front.
The lake supports 10 million migratory birds annually. Brine shrimp — the keystone species of the food chain — are in critical decline. Lake recovery is ecosystem recovery across the entire Pacific Flyway.
The solar corridor delivers 200+ MW to the Western Interconnect as a co-benefit of water transport. The pipeline is not a cost center — it is dual-use critical infrastructure with measurable ROI.
The time is now
The engineering is solved. The physics is bulletproof. The route exists. What remains is the decision to act — before the window closes permanently.
