Help the farmers grow food for 2 years without letting the ground sink!
🌱Tap a thirsty field to water it
☁️Tap clouds to catch rain for the underground water
⚠️Keep the blue water above the red line
River water is free. When the river is empty, water is pumped from underground. Pump too much and the clay squeezes flat: the ground sinks and never comes back.
Great job!

Real science: in summer 2026 the NASA-ISRO NISAR satellite measured the ground in California's Central Valley sinking about 7.8 cm (3 inches) in just 108 days, because farms pumped water from deep underground. Part of that sinking never comes back.
