Each site is a section of the Watermark platform — pivoted by basinstate. Live & building sites open; queued and tracking
sites route to their coming-soon / watch page.

Each site is one Watermark investigation. The page color says what opens; the campus line is the build on the ground — two different clocks.
A month-by-month climograph of net atmospheric withdrawal — reference evapotranspiration
(ET0) minus precipitation — for the receiving basin, with the JSMC data-center campus's modeled cooling draw read against the cited
seasonal low flow. Switch months and hover the field: the ink hairline is the deficit
boundary (ET0 = precip), and the growing-season window is exactly when the river sits at its
summer design low flow with no rainfall buffer.
The climograph surface (net atmospheric withdrawal = ET0 − precipitation) is the cited NASA
POWER climate normals with FAO-56 reference ET — [reference]. The per-month
low-flow multiple screens the modeled buildout consumptive
draw against the cited seasonal low flow (30Q10 summer / 7Q10 annual), so that ratio is a
labelled screening estimate — [inference], never [verified]
and not a measured withdrawal.
The seasonal screen
Net atmospheric withdrawal (ET0 − precip, mm/day) per month, and the modeled cooling draw
against the cited seasonal low flow. The growing-season multiple (3×
the summer 30Q10) is the load-bearing read the annual figure (24.3×
the 7Q10) understates.
