17 Major Flooding: Disasterous flooding traveling northward from Canoas Creek overbanking. CA-87 flooded under Almaden Expressway. Almaden Terrace Apartments, Guadalupe Almaden Neighborhood, and Northern Cross Neighborhood inundated. Water may cross east of CalTrain Railroad Tracks and continue through the industrial and commercial area bounded by Curtner/Tully and Barnard Avenue towards Monterey Road. If flooding is sustained, floodwaters will flow further north along 1st street, flooding surrounding neighbor
16 Major Flooding: Entire Garden Neighborhood is inundated. Mill Pond Neighborhood is inundated. Area west of CA-87, South of Curtner and East of Almaden flooding. Water travelling north of Curtner.
15 Moderate Flooding: Significant flooding in the Canoas Garden Neighborhood. Homes to the south of Canoas Creek along Nightingale are inundated. Water flows north along streets towards Curtner and Almaden Expressway. Mill Pond at risk.
13.5 Minor Flooding: Overtopping occurs upstream of Nightingale Drive behind private residences and upstream of the culvert. Waters flow along streets to the north and south.
9.5 Action Stage: Calero Avenue and Blossom Hill Road possible weak points for debris and street flooding. Creek can be heavily influenced by Guadalupe River when flow is above 2000 cfs (7'-7.5' stage at Almaden Expressway) causing backwater conditions.
