Water over ice
Yesterday afternoon while I was brewing beer (more on that later), I took Nika out for our usual walk. We go across the bridge, walk along the north side of the Creek until we get to the confluence of the Creek and the Slough (the “stick throwing spot”), then drop down onto the Creek and walk back. Typically we’ll walk under the bridge and come back up onto land near the red cabin. Yesterday we kept going another few hundred feet until we came across some overflow. It was only a few inches deep and didn’t seem to be advancing.
Last year we got some overflow early in the winter, but by January it seemed to have stopped and we didn’t get anymore until the Creek broke up at the end of April. This year it’s been lightly overflowing in spots around our house pretty much all winter. With all the late season snow, it’s been a good thing because it keeps the depth of the snow on the Creek lower than it would be. I did use snowshoes a couple times because the snow had gotten deep enough that it wasn’t fun to wade through, and Nika had a hard time swimming through it.
In the evening, I got up to get myself a Silver Gulch Hefeweizen, and was surprised to see running water over the whole length of the Creek. I went outside to investigate and take some photos. The water flowing over the ice was about 10 inches deep (you can see it in the photo of my boot on the right). The photo on the left (assuming you’re reading this on my blog and not in an aggregator…) shows what it looked like when I initially got out there.
I walked downstream through the overflow and came to the end of it near the stick throwing spot. It was pretty wild walking through almost a foot of water on top of the ice, and as I neared the bend at the slough, it started getting shallower and shallower. Eventually, I walked up onto the snow and took a few photos as the water advanced.
Expanding end of the overflow
This morning the water level on top of the ice is up to 14 inches. The low temperature last night was -14°F (and it’s still -10°F as I type this), so the margins of the overflow are already frozen to around ½ an inch, and there’s steam rising from the flowing center. It’s great to hear flowing water again, but that much water suddenly appearing does make me a little nervous. We’re not in any present danger as the low point in the dog yard is easily three feet higher than the current level of the slough, but when a foot of water can suddenly appear over the frozen ice, who knows?
The top of the slough now has some water in it too, but I haven’t walked out on the trail to see how far the water has advanced. Depending on how much more water there is and the average temperature for the upcoming weeks, it looks like our walks on the Creek might be over for this winter. I’m curious to see how all the water will affect the breakup date this year. The weather service is predicting lows in the 20s and highs near 40 all week in Fairbanks, but that probably means lows near zero and highs barely above freezing here in the Valley, so breakup probably isn’t happening this week.
