Big Sur River Above Flood Stage for Fifth Time This Year

Heavy pre-dawn rain has pushed the Big Sur River above the 10-foot level that marks its official “flood stage” for the fifth time in less than two months.

As of 9:00 am, the river was at 10.30 feet, which indicates a flow of 3,530 cubic feet per second.

On January 12, the Big Sur River hit 12.34 feet (or 7,650 cfs – more than twice the current flow); the second highest peak recorded since the gauge was installed. The highest was an amazing 10,700 cfs, recorded in January 1978, following the Marble Cone Fire.

This morning’s rain can’t be helping the situation at Pfeiffer Gulch, where a slide has been slowly pulling down the Highway bridge. Interestingly, when the bridge was built in the 1960’s, Caltrans erroneously signed it as the Pfeiffer Canyon Bridge and, taking their cue from the sign on the collapsing bridge, everyone now seems to be referring to the place as Pfeiffer Canyon.

It’s not the first time this ravine has undergone a name change or, apparently, had bridge trouble. According to Clark’s Monterey County Place Names, the Pfeiffers themselves knew the place as Burnt Bridge Creek.

Noon Update: As of 11:45 the Big Sur River was still rising and had reached 10.85 feet, or 4,370 cfs.

1:00 pm Update: As of 12:45, the Big Sur River had reached 11.07 feet (4,730 cfs). The Carmel River is also rising and is projected to crest more than a foot above its January high water mark. If this happens, there will almost certainly be some flood damage.

2:00 pm Update: The Big Sur River has been level at 11.10 feet (4,790 cfs) for the past half hour. Rain is expected to become more intense this evening, so another rise will be possible tonight.

5:30 pm Update: As of 5:15 pm, the Big Sur River had receded to 10.3 feet (3,530 cfs); which is still above flood stage. Rain is beginning to pick up again over the Big Sur watershed and, if that continues, the river may begin rising again soon.

7:00 pm Update: Hard rain is falling and the Big Sur River is on the rise again. 10.40 feet (3,680 cfs) as of 6:30 pm.

9:00 pm Update: The Big Sur River is rising quickly and has surpassed this afternoon’s peak. As of 8:45 it was at 11.78 feet (5,960 cfs).

10:00 pm Update: Has the Big Sur River found its peak? It made it to around 12.22 feet, just shy of last month’s high water mark of 12.34 feet (the 2nd highest peak ever recorded), but has now (as of 9:45 pm) dropped back to 11.97 feet (6,310 cfs).

11:30 pm Update: The Big Sur River is rising again and, as of 11:15 pm, was back to 12.13 feet (6,570 cfs).

Midnight Update: That rise was short-lived. The Big Sur River is back under 12 feet and falling. Unless unexpectedly heavy rains arrive, it should continue to fall throughout the night.

12:30 pm 2-21-17 Update: The Big Sur River finally went back below flood stage around 11:00 this morning. Its twin peaks last night may have been a bit lower than the January high water mark, but the fact that it remained above flood stage for more than 24 hours is probably some kind of record.

As of 11:45 am, it was at 9.9 feet (2,940 cfs).
