7. Water Availability Issues for Bureau States • Drought conditions in western Texas • Extreme drought in Trans-Pecos climate division in Texas and in southeastern New Mexico • Recent locally heavy rains in northeastern Oklahoma an improvement to drought conditions

8. Water Availability Issues for Bureau States (cont.) • Drought designation expanded for parts of the Northwest and northern Rockies • Wildfire potential still above normal for all of California and normal for Nevada

9. Water Availability Issues for Non-Bureau States • Alabama -- Decline of groundwater levels by 100 feet due to pumping • Alaska -- Permafrost decreases access to groundwater • Arkansas -- Decline of groundwater levels by 60 to 300 feet due to pumping • Connecticut -- Surface water cannot meet demands and SDWA requirements

10. Water Availability Issues for Non-Bureau States (cont.) • Delaware -- Decline of groundwater levels by as much as 150 feet • Florida -- Decline of groundwater levels by as much as 150 due to pumping, and coastal area salt water intrusion • Georgia -- Surface and groundwater supplies not readily available near large cities, and coastal area salt water intrusion

11. Water Availability Issues for Non-Bureau States (cont.) • Hawaii -- Water resources susceptible to prolonged droughts • Illinois -- Decline of groundwater levels by more than 850 feet in northeastern state due to pumping, and surface water inadequate during drought in southern two-thirds of state • Indiana -- Decline of groundwater levels by 20 feet due to Ag pumping

12. Water Availability Issues for Non-Bureau States (cont.) • Iowa -- Groundwater not available in southern part of state, surface water deficiencies during drought, and Missouri River changes have lowered levels in wetlands and lakes • Kentucky -- Some areas with inadequate groundwater, and surface water inadequate during drought

13. Water Availability Issues for Non-Bureau States (cont.) • Louisiana -- Decline of groundwater by as much as 430 feet in southern, and central state and several rivers have low flows restricting surface water availability • Maine -- Existing and potential surface and groundwater sources not sufficient for southern state

14. Water Availability Issues for Non-Bureau States (cont.) • Maryland -- Decline of groundwater levels by as much as 85 feet in south state • Massachusetts -- Groundwater withdrawals for public water supply may lower levels in eastern state • Michigan -- Groundwater inadequate in northern state during droughts

15. Water Availability Issues for Non-Bureau States (cont.) • Minnesota -- Irrigation and domestic users competing for groundwater • Mississippi -- Decline in groundwater levels along Gulf coast, northeastern, and western state due to pumping • Missouri -- Decline in groundwater levels by several hundred feet in southwestern state due to pumping

16. Water Availability Issues for Non-Bureau States (cont.) • New Hampshire -- Inefficient distribution system can cause water supply to not meet treatment standards and result in shortages • New Jersey -- Surface water supply to northern state only adequate when precipitation > average, and parts of state aquifers not fully used due to environmental/institutional constraints

17. Water Availability Issues for Non-Bureau States (cont.) • New York -- Decline of groundwater by 18 feet and decreases in stream flow by 90% in parts of Long Island, and droughts can cause inadequate water supply in New York City • North Carolina -- Approaching surface water supply limits in the Piedmont area, and coastal plain aquifers declining and experiencing saltwater intrusion

18. Water Availability Issues for Non-Bureau States (cont.) • Ohio -- No issues identified • Pennsylvania -- No issues identified • Rhode Island -- Water supply systems cannot meet demands during droughts • South Carolina -- Scarce groundwater in Piedmont areas with reliance on variable surface water, and declining groundwater in southern state from Ag pumping

19. Water Availability Issues for Non-Bureau States (cont.) • Tennessee -- Subject to surface water shortages in eastern and central state during droughts • Vermont -- No issues identified • Virginia -- Water supplies not sufficient for future demands in southeastern state, and decline in groundwater up to 200 feet in some areas

20. Water Availability Issues for Non-Bureau States (cont.) • West Virginia -- Surface water shortages in southern state during drought • Wisconsin -- Decline in groundwater up to and exceeding 100 feet in eastern and southeastern state due to pumping
