Cultural Choices


And if it seem evil unto you to serve the Lord, choose you this day whom ye will serve...

If you have not chosen the kingdom of God first, it will in the end make no difference what you have chosen instead.

Early Flooding 2017

The first major flooding incidents in Utah Valley are purely man-made.

The gates of the seldom-used spillway at Deer Creek Reservoir were opened.



KSL reports on warnings from the NWS about release of excess water from Deer Creek Reservoir into the Provo River.


In order to provide better control for spring runoff, the water management administrators decided to allow excess flow from Deer Creek Reservoir now.  The spillway and dam hydro facilities were opened to bleed off some of the totally full reserves.

Over the weekend, this resulted in flooding all along the Provo River down to Utah Lake.

Water roaring over the weir at the collection dam near Nunn's Park.

The popular riverside trail through Provo Canyon was later closed as parts of the pavement was undercut by the river current and fell into the rushing waters.

Deseret News article on the canyon trail closure.  SLTrib also mentions.

If this is the full extent of flood damage, residents of Utah County have dodged the bullet.

Utah Snowpack 2017 - 3 May Edition

Utah snow pack in our mountains has peaked and is beginning the season runoff.  As the snow melts down from the highest mountains, some of the snow totals indicated by Snotel monitoring are still quite deep.

Mammoth-Cottonwood, my reference point.  This graph plots Snow Water Equivalent and Precipitation Accumulation for 2017 and 2016. Although significant snow melt has already taken place this spring, the remaining accumulation is still about even with the total from last year. Within the past couple of weeks, the precipitation accumulation has continued a steep climb.


The most recent view of snow and water at Gardner Peak in the southwest corner of Utah shows snow melt tapering off, and precipitation totals comparable with last year at this time.



At Mammoth Pass in California, the melt of the immense snow pack from this season is just showing early signs.  It is likely to challenge local flood control resource beyond limit.





And again, for scale, Ben Lomond Peak in northern Utah has started early runoff, but still holds enormous potential.

Watch out, it's on the way!
