- No new reservoirs proposed
What's at Issue?
Region P is the smallest of the planning regions. While the population increases slightly, due to a reduction in irrigation demands, the water needs of the region actually decrease through 2060. The majority of the water used in this region is for irrigated agriculture. The region intends to temporarily overdraft their groundwater resources in order to compensate for peak demands during drought of record conditions.
Action Items
Here are some of the items the Region P Planning Group must address.
 Conservation and Drought Management
For conservation and drought management, the plan needs to...
- Evaluate drought management measures as a water management strategy. Each water user group with a shortage should use a drought management strategy derived from its drought management plan as a way to meet their water needs. The regional plans in the state are based on a drought of record and it only makes sense that drought management should play a large role in planning to meet the region's water needs during that drought period.
Environmental Flows
To secure the protection of flows for fish and wildlife, the plan needs to...
To secure the protection of flows for fish and wildlife, the plan needs to...
- Recognize environmental flows as a water demand and seek to provide reasonable levels of environmental flows in the region.
- Discuss potential for groundwater contributions to surface water flow through seeps or other means.
- Designate stream segments in the region that meet the criteria as having "unique ecological value". The Texas Parks and Wildlife Department recommends 5 segments for designation in this region.

sustainability
Sustainable management is maintaining a constant amount of water in the aquifers. This means that average withdrawals do not exceed a rate which can be replenished through recharge on a continual basis while maintaining adequate outflows, such as base and springflows, from the aquifer.
