Press Release

Posted: December 11, 2022

Washington – Today, Rep. Mike Thompson (CA-05) secured the inclusion of the Conn Creek Dam Safety Project study and the Napa River Dredging study in the National Defense Authorization Act (NDAA).

“Napa’s waterways are vital to the economic wellbeing and environmental protection of our community,” said Thompson. “Proud to have secured the inclusion of the Conn Creek Dam Safety Project study and the Napa River Dredging study in the NDAA. These studies will help our community maintain our waterways and protect us against the impacts of flooding and climate change.”

“Congressman Thompson’s assistance in procuring funding for the Conn Creek Dam Spillway Project is integral to the safety of the City of Napa and neighboring communities in light of our changing and probable maximum storms,” said Napa Mayor Scott Sedgley. “In concert with the Conn Creek Spillway work, the Napa River Dredging Study is critical not only for the environmental health of the Napa River but for the efficiency in moving storm water to the Pacific Ocean.”

The feasibility study of the Conn Creek Dam spillway will determine improvement requirements to sustain maximum flood levels and prevent spillway overtopping and failure of the earthen dam due to 24-hour maximum precipitation hitting the tributaries of Lake Hennessey.

The Napa River Dredging study will ensure the needs of Napa and surrounding communities are considered, includes climate change impacts, and adheres to the Living Napa River concept.

The NDAA passed the House by a vote of 350-80.
