6 PM Sunday update:  Despite my ho-hum attitude this morning, the Mohawk has risen quickly this afternoon at Schenectady, reaching about 217′ at 5 PM, with 216′ being the Action Stage, and the Flood Level at 220′.

Nonetheless, the National Weather Service prediction service has not yet issued any predictions for the Mohawk at Schenectady.  That may be because the water level will depend on the happenstance of weather ice chunks and floes start accumulating at bridges or bends of the River.

The water was still moving smoothly and fairly well along Riverside Park at 5 PM, although it has filled up with ice debris, and does not have large open water areas as it did this morning.

I was told by an Alplaus fire department officer that the River was almost at a standstill at Rexford, around 4:30 PM.  The water may start backing up and rise more at Schenectady should it slow further at Rexford.  Note that NWS has already predicted that the Mohawk has peaked without flooding at Little Falls, and predicted to peak at five feet below flood level at Cohoes overnight.

. . . Sunday morning update (Jan. 12):

According to the Sunday Times Union, it was fogging, not flooding, that was a problem yesterday or overnight in the region, and the National Weather Service has reduced its alert from a Flood Warning to a Flood Watch for eastern New York, with the alert expiring at 6 PM Sunday.

IMG_3319-001 Officials and regular folks have been watching creeks and rivers around eastern New York this weekend to see whether rains and warm temperatures will cause the streams to overflow, with special worry over ice jams caused by the melting crusts of ice that have formed during the recent spate of frigid weather.  See the Albany Times Union, “Flooding possible in parts of region” (Saturday, Jan. 11, 2014) Here along the Schenectady-Stockade stretch of the Mohawk, rapid snow melt can cause flooding, but this time of year the culprit is much more likely to be large chunks of ice jamming at the CSX trestle, with waters swollen by overflowing creeks upstream.

After a number of trips to my backyard and Riverside Park, at the end of my block, I can say that things look pretty good along the Mohawk as of Saturday evening.  (Disclaimer: the late-afternoon fog [see photo above] might have been covering a drastic rise in the water level, but I doubt it.) The collage below gives examples of scenes that I have found this weekend at the River (click on it for a larger version).

  • I plan to report on any developments or lack thereof tomorrow, Sunday. (especially if the creek does rise)
  • In March 2009, we had a major ice-jam episode along Riverside Park.  It’s worth a look.
