Low upstream inflows, elevated evaporation from above-normal temperatures, and cumulative storage losses of over 15 feet in the past year have positioned the reservoir near thresholds that trigger deeper shortage tiers. USBR 24-month modeling released in recent months projects further declines under most-probable and minimum-inflow scenarios, while the August 22 finalization of post-2026 operating guidelines imposes additional Lower Basin cuts and conservation requirements that have yet to reverse the downward trajectory. These verified hydrologic trends and official forecasts underpin trader consensus favoring substantial additional drops.
