Special Condition P of the Army Corps Permit states "The pressure transducer will be installed one year prior to the start of construction, monitoring will continue through two years post -construction of the project. Baseline and Annual monitoring reports will be submitted to the Corps that include a graph of water level and precipitation data." In addition, the Division of Water Resources Permit Condition 3 requires annual monitoring reports, including a graph of water level and precipitation data, be submitted to the DWR by December 31 each year of monitoring. A pressure transducer was installed in March of 2022 and data collection is ongoing. Please find attached graph of this past year's daily flow measurements of the unnamed tributary immediately downstream of the permitted project, prior to entering Brushy Creek. Additionally, please find a graph of the daily precipitation data collected at a nearby on -site weather station less than I mile away. The project was recently completed and data will be collected for an additional two years. The actual watershed was diverted into the constructed basins, bypassing this subject segment of Ms. Amanda Jones Fuemmeler Page 2 stream, near the first week of October. Since that time, the stream clearly remains with sufficient flow due to localized springs in the area. There should be no concern with depletion of flow in this segment of the stream due to the construction project. Additional copies of these graphs are being sent to Division of Water Resources personnel at both the Asheville Regional Office and the 301 & Buffer Permitting Branch. If you have any questions regarding this matter or require further information, please do not hesitate to contact me at (828) 592-2764. Sincerely, .�Mtll � Jeffrey S. Ferguson, P. E.
