Shizhu Infrastructure Timeline

This entry condenses the dated surface-operational sequence for the Shizhu containment corridor. It exists to keep date-bearing infrastructure claims separate from doctrine and from lineage description. The archive uses these dates for cross-reference: road construction, early pond visibility, reservoir loading, hub expansion, and population clearance all matter because they let later readers compare the formal MSS timeline against heterodox notes, local governance material, and wider GDCC interpretation.

The sequence preserved here is operational and surface-facing. It does not attempt to infer motive beyond what the dates themselves support.

Claims

c0001 - A northern astro-pond installation is already visible in 2004 imagery

One northern pond in the Dongguaping-Dayakou-Hemaotang corridor is identifiable as operational in 2004 satellite imagery. The installation predates the completed road network and therefore indicates that MSS survey teams had already fixed at least one subsurface target before the visible surface-build phase matured into the later wind-farm cover infrastructure.

c0002 - The main ridge-road and turbine-pad cover network is built between 2009 and 2015

Between 2009 and 2015, MSS surface operations built the ridge-road network, circular turbine pads with horseshoe access roads, and the Construction Hub that later anchored the corridor cover story. During the same interval, pond sites were filled, gravel pits were revegetated, and displaced Tujia settlements were cleared from the visible operational footprint. By the end of the interval, the wind-energy explanation could carry the visible surface geometry without additional imagery suppression.

c0003 - Construction Hub expansion intensifies between 2018 and 2021

The MSS Construction Hub expands between 2018 and 2021 with a large new roofed structure inconsistent with ordinary wind-farm maintenance requirements. This late expansion postdates the initial excavation phase and coincides instead with increased monitoring or data-processing capacity. The visible change marks a shift from emplacement and concealment toward sustained operational use.

c0004 - Reservoir loading and Shizhu build-out overlap in the same operational window

Three Gorges reservoir filling begins in 2003, Shizhu surface operations are visible in 2004, and the corridor's main infrastructure matures through the period leading to full pool in 2012 and beyond. GDCC treats the temporal overlap as analytically significant because the reservoir adds sustained pressure to connected karst and fault intervals while MSS monitoring capacity rises on the same western corridor. The timeline alone does not prove coordination, but it makes coordination a live question.
