SHEP spotlight: DO system

SAVANNAH, Ga. – Contractors with CDM Constructors Inc. are finishing concrete placement for the intake structure on the downriver site of Dissolved Oxygen Injection System. The project is scheduled to be completed by the end of the year.

The system is one feature in the environmental mitigation for the Savannah Harbor Expansion Project.

As discussed previously on this blog, the DO system will force oxygen into river water via two separate plants using proprietary Speece cones to super-oxygenate water taken from the river and re-introduce it back into the river. The system is designed to provide 40,000 pounds of oxygen per day into the estuary to mitigate for the effects on dissolved oxygen from the harbor deepening.

Here’s a small scale version of how the system operates:

Spring arrived early but forgot to pack rain

February’s rainfall left much to be desired as the sub-basins struggled unsuccessfully to break the two-inch mark.

Thurmond collected the most at a paltry 1.78 inches (41 percent of its average, 4.3 inches), while Hartwell and Russell registered under 40 percent – just 1.77 and 1.64 inches, respectively. Continue reading

Contractors on pace to finish 5 SHEP-related features in 2017

SAVANNAH, Ga. – To say Spencer Davis has a few irons in the fire is an understatement.

As the senior project manager for the Savannah Harbor Expansion Project, or SHEP, Davis manages the multimillion-dollar project that has eight separate environmental mitigation features outside of the actual harbor and entrance channel deepening.

Now more than two years in, contractors continue to push the project forward on several fronts and are expected to wrap up five contracts this year. (Click the subheadings below to see photos from these features on our Flickr page). Continue reading

Drought flow rates changed in February: here’s why

Many of our stakeholders have asked why outflow at Thurmond Dam recently increased from 3,600 cubic feet per second (cfs) to 4,000 cfs. Let me answer those questions and perhaps shed some light on our operational process.

First some background:
Our water managers only have limited discretion when making operational decisions on Thurmond discharge during drought. They are bound by law to follow the Savannah River Basin (SRB) Water Manual. The Drought Contingency Plan (DCP), a part of this manual, directs discharge volumes at specific lake levels, seasons, and in some cases flow rates of the Broad River. Continue reading
