The baseline survey of ecological condition of streams within the Guadalupe River watershed was completed in 2012, and this reassessment survey was completed ten years later in 2022. The survey focuses upon stream conditions in the watershed as a whole, and in two primary areas of interest: the Urban portion of the watershed within Santa Clara Valley, and the Non-urban portion of the watershed in the Santa Cruz Mountains. The survey was designed to answer two questions:

• What is the overall ecological condition of streams in the Guadalupe River Watershed, as well as in the Urban portion and the Non-urban portions of the watershed?
• How has stream condition changed over the past 10 years?

Overall, the reassessment survey found that the streams in the Guadalupe River Watershed are primarily in Fair condition, and that condition largely has not changed in the past 10 years. However, much more detail about stream conditions and how they are changing can be uncovered. These results are further explored in this report.
