Pinal Creek Floods blog explained

(UPDATE as of July 30, 2023:  We began this blog in early July 2021. We wished to discuss historic Pinal Creek floods.  We also wished to highlight the urgent need for early warning about potential floods pouring forth from The Telegraph Fire burned area. 

There was scant interest in this blog. In fact, the blog received less than 50 views so we stopped updating it about two years ago.  As of July 30, 2023, we felt it is important to revisit the information contained in the original blog.  Residents of Globe and the surrounding areas really need to be fully aware of Pinal Creek's ever-present potential for epic monsoon season flooding.  This blog could well become an annual reminder of such flooding potential.

While most monsoon rain events are benign, some such storms carry deadly consequences.  It is vitally important for residents and public safety officials to be always aware of what "might" happen with any given monsoon event in Pinal Creek's course through Globe and adjacent areas.

The narrative below the dashed line was written in early July 2021.)

--------------------------------

The Telegraph Fire was a "game changer" for Pinal Creek Floods.  The fierce fire forged immediate and lasting changes to the Pinal Creek's Watershed in and near the Pinal Mountains.  It is very possible those profound changes will cause more frequent flooding as well as higher flood flow volume in Pinal Creek through Globe and vicinity.

This blog was created July 6th, 2021, to help leaders, residents and visitors understand Pinal Creek's flood history and watershed characteristics.

In this blog we will address numerous topics, including the infamous August 17, 1904 Flood.  Then we will discuss the July 29, 1954, Pinal Creek flood.  Because it's closely related in time and place, we will also cover the July 20, 1954, flood that hit Miami, Arizona, via Bloody Tanks Wash.  

We will cover high flow events in Pinal Creek from 1981-2015 before describing in detail the four July 4, 2021, Pinal Creek flood flow events through Globe.

The blog will also attempt to address the scope and scale of potential fluvial impacts brought about by the Telegraph Fire and discuss why we think that fire has forever changed the fluvial flood response of Pinal Creek.

Lastly, we will provide recommendations for an emergency monitoring and warning system to help Globe and Gila Country citizens stay safe during times of future flood peril.

In a nutshell on this blog, we will help readers understand why we think portions of Globe, Arizona, are at their highest risk of catastrophic flooding since Anglo settlement began in the 1870's.

Potential Pinal Creek Flooding a serious situation that requires recognition and response from officials at all levels as well as potentially affected residents and businesses throughout the new (and as yet unknown) flood channel of Pinal Creek.

That's what this blog is all about.  It has a very narrow focus.  It's ONLY about Pinal Creek Floods and related topics.

This blog is a "work-in-progress."  We will be adding new content and editing old content regularly in the days and weeks ahead.
