Colorado River river trip to assess hydropower potential

1923 Colorado River river trip to assess hydropower potential of Grand Canyon

This is an old film produced by the USGS (and linked from their website) that shows footage of 1923 Colorado River river trip to assess hydropower potential of Grand Canyon (1923).  This is a silent video produced in black and white that shows the excitement of the river trip and some of the trials and tribulations of these early adventurous public servants of the U.S. federal government.

Additional information can be found at this link to the USGS’s archival material.

Floods as a restoration tool in the Grand Canyon

Flood as a restoration tool in the Grand Canyon

The U.S. Department of the Interior has periodically been releasing large volumes of water into the Grand Canyon in an attempt to mobilize sediment and rebuild beaches in a river system that has been sediment deprived since the installation of the Glen Canyon Dam in 1963. In November 2013, they planned for a high flow release (>34,000 cubic feet per second) into the Colorado River, which normally flows at 8-9,000 cfs. They maintained high flows for 4 days during a period that the Paria River was releasing large amounts of sediment into the Colorado River.  River managers hoped to entrain the high sediment load of the Paria using high flows in the Colorado River so that they would be carried downstream and deposited further down than they normally would be.  Flooding, flood routing, river restoration and Colorado River water resources are all subjects that I am very interested in being more involved with in my future research endeavors.

Rising temperatures threaten Salt Lake City’s water supply

 

Salt Lake City relies on water from several watersheds including four creeks on the western side of the Wasatch Mountains and water that’s pulled in from the more distant eastern side of the mountains. A new study shows how climate change is likely to affect the various creeks and streams that help slake Salt Lake City’s thirst. (Map credit: CIRES)

Rising temperatures threaten Salt Lake City’s water supply

This article from researchers at NCAR (National Center for Atmospheric Research) and CIRES (Cooperative Institute for Research in Environmental Sciences)  appears to be an interesting report linking Salt Lake City’s water supply to changing temperatures and precipitation.  I will spend some time reviewing the report in the next week or so, but until I do, check out a summary of the report here.

Quantifying Colorado River water deliveries

Quantifying Colorado River water deliveries

I really enjoy innovative graphics that convey quantitative data in simple understandable ways. Here’s a great example of a graphic that shows how much Colorado River Water has flowed into and out of various parts of the Colorado River basin and the States and communities that rely upon it for their water. This map shows how no Colorado River water makes it into Mexico anymore.  It also shows how much water into California and Arizona.  Very interesting.  More info can be found at this link.
