Farms can return up to 665K AF/yr — about 83% of the 800K the lake needs. The rest isn't a bigger ask on farms; it's other sectors pulling their own levers.
Beyond this map
Cities — the basin's biggest untapped pool; no firm savings number yet.
Conserve as demand grows — every gallon saved on the Wasatch Front pushes back the $2B+ Bear River diversion (~86K AF/yr off the lake; conservation has already delayed its need to ~2050).
Efficiency, with an asterisk — lining ditches & sprinklers can cut the return flow downstream users depend on.
Levers need governance — leasing programs & canal-share reform are what let this water actually move.
