Three Gorges Dam – Major Concerns
How It Works with Other Yangtze River Dams
China operates a coordinated cascade of dams on the Yangtze and its tributaries for flood control, power, and navigation. The system includes major dams such as:
Joint Operation Strategy:
Recent Performance:
Summary
The Three Gorges Dam faces significant long-term challenges: structural integrity, seismic activity, landslides, sediment buildup, water pollution, ecosystem damage, and social displacement. It operates as the centerpiece of a vast, integrated dam system aimed at flood control, hydropower production, and navigation support. While the cascade has demonstrably reduced flood impacts, it comes with a high environmental, geological, and society issues.

The disaster in Texas is severe flash flooding along the Guadalupe River in central Texas, not a dam collapse. Here's the detailed situation:
What is the same? North Carolina had a dam overflow. Texas - also near a dam. China is now in a disaster zone from rain and DAMs in the area. Dams are sitting time bombs; they have a long history. What happens is quite simple, they create a lot of rain, the dams get full, and WHOOPS they have to release the excess water, flooding out people and things in the path.

Section 1: Overview – Texas Hill Country Flash Flood
Location: Kerr County, Texas (Hunt to Kerrville, along the Guadalupe River)
Date: July 3–4, 2025
Primary Event:
Impact:
Key Point:
This was not a dam collapse, but rather extreme flash flooding triggered by a high-volume rain event.
Section 2: Dams in the Kerrville/Ingram Region
Major Dams Involved or Nearby:
Canyon Dam (Creates Canyon Lake)
Type: Large rolled-earth flood-control dam
Built: 1958–1964 by U.S. Army Corps of Engineers
Function: Flood control, water supply, hydroelectricity, recreation
July 2025 Status:
Type: Small, low-head, 20-foot earth dam near Kerrville
Status:
Overtopped on July 4 — water flowed over the top due to heavy rainfall
No structural breach
No intentional release — a passive overflow, not a failure
Did contribute to downstream surge
Kerrville Lake Dam (Center Point Lake Dam)
Earth dam, ~20 feet high, built in 1956
For flood control and recreation
Not implicated in failure
Kerrville Ponding Dam
Other Dams Downstream (Managed by GBRA)
