subsidence in Harris County

Groundwater Management Area 14 to Hold Joint Planning Committee Meeting on January 20

Mark your calendar and sign up now. Groundwater Management Area 14 (GMA 14) will meet by webinar Wednesday, January 20th at 10 AM to continue the process of developing a set of desired future conditions for area aquifers. The standards will eventually determine groundwater availability and affect other issues such as subsidence.

GMA 14 includes the 15 colored counties above. Each color represents a different Conservation District. Montgomery County (dark blue) has the Lonestar Groundwater Conservation District.

GMA 14 engages in a joint planning process and includes representatives from Bluebonnet, Brazoria County, Lone Star, Lower Trinity, and Southeast Texas groundwater conservation districts, plus two subsidence districts. GMA 14 spans 20 counties. It is one of 16 groundwater management areas in the state of Texas. 

High Stakes

Groundwater availability is a growing concern in the management area due to subsidence, water table reduction, wells running dry, the triggering of geologic faults, impacts to infrastructure, foundation issues, and providing a sustainable basis for future growth.

The last available subsidence maps, for instance, showed the north Harris and south Montgomery County area sinking 2 feet relative to the Lake Houston Dam.

Pumping 115,000 acre feet per year would cause up to 3.25 feet of subsidence in southern MoCo. That’s far more than the 1-foot in the Desired Future Conditions definedby GMA14.
The same amount of pumping would cause up 3 feet of subsidence in parts of Kingwood and Huffmanand a foot or more in much of the rest of Harris County.

Because aquifers travel under several counties, what happens in northern Montgomery County can impact southern Harris and Galveston counties, especially where people live closer to sea level.

How Much is Safe to Pump?

In determining groundwater availability targets, this month’s meeting will focus on:

  • Socioeconomic Impacts Reasonably Expected to Occur
  • Feasibility of Achieving the Desired Future Conditions
  • Other Relevant Information (including fault movement). 

In all, GMA 14 considers nine factors in the join planning process: 

  • Aquifer Uses and Conditions
  • Water Supply Needs and Management Strategies
  • Hydrological Conditions
  • Environmental Impacts
  • Impact on Subsidence
  • Socioeconomic Impacts
  • Private Property Rights
  • Feasibility of Achieving the desired future conditions
  • Other Relevant Information
