The Old Farmer’s Almanac is predicting that “precipitation and snowfall will be average or above average throughout the Intermountain Region. The snowiest periods will fall in mid-November, early and late January, and mid-March.” We shall see.

have been posted again for Castle Valley, six days after an intense flash flood that inundated a wide swath of the valley with mudflows. Since then the Town has done absolutely nothing to excavate the sediment-filled ditches and restore their capacity so that they can efficiently convey storm runoff and protect private property.

occurred late this afternoon in response to an enormous storm cell that passed over the valley dropping about a half-inch of rain in less than an hour on hard-baked soils. Overland flow and sheet-flooding began immediately and ditches ran at full capacity along roadways for more than an hour. The National Weather Service did post both flash flood and severe thunderstorm warnings for the region and the last time an event this intense occurred was around 2010.
Peak runoff down the lane occurs as the storm cell moves eastward, with both roadside ditches running at full capacity. But a rainbow appeared and no personal property was damaged.
The low swale on the east side of my property took some runoff and sediment from small breaches in the berm along the roadside ditch.
UPDATE: The morning after in the mud bowl as the Town’s grader gets to work. There’s a lot of ditch maintenance that needs to happen beyond just clearing debris from the road surfaces.
