Hello,
Attached is the water well permit summary report which includes data through 3rd quarter of Water
Year 2025 (April 1, 2025 – June 30, 2025).
Highlights for this quarter and Water Year:
Water Well Data continues to trend downwards (total issued, total finaled, total destroyed,
total repaired).
No dry wells reported in WY2024 or WY2025 so far (these reports would come in along with a
well permit repair/replacement).
Executive Order N-7-22 has been repealed; future reports will not include additional N-7-22
wells.
Feel free to contact me if you have any questions.
Thank you,
