Scrubbing and Skimming

Skimming – A recent story on the Corps of Engineers use of algal skimmers in Florida to help combat toxic algal blooms reminded me of North Carolina’s own efforts to combat algal blooms. In Florida, the Lake Okeechobee skimming process uses “dissolved air flotation”…

Upstream Benefits

The Falls Lake Nutrient Strategy put in place by NC DEQ in 2010 provides more than just drinking water protections for Falls Lake. Communities in the Falls watershed such as Durham benefit from the rule protections, too.  Durham’s drinking water supply comes from Lake…

Stewardship

A necessary step in the environmental mitigation process is to secure long-term stewardship of the project site.  Among the responsibilities of the steward is to visit and inspect mitigation sites to make sure that the terms of the easement are being honored.  For the…

Raleigh’s Welcome Change

The City of Raleigh got some good new. As reported on WRAL, the Army Corps approved the City’s request to reallocate Falls lake’s storage toward drinking water allowing the City to increase the drinking water withdrawals by 22 million gallons a day.  As we’ve…

25-Year Jordan Water Quality Trends

A US Geological Survey Report released late in 2018 provides a needed review of water quality trends for select NC rivers and streams over the last 25-years (1989-2013). Importantly, the report focuses on the quality of water flowing to drinking water reservoirs in North…

Extreme Storms, Harmful Blooms

Interesting insight from UNC Research Hans Paerl on what impacts we may be seeing from the extreme storms like hurricanes Matthew and Florence in the coming years.  

Chesapeake Check-In

The Chesapeake Bay has experienced problems similar to those in NC’s estuaries as it relates to nutrient pollution. Low-oxygen “dead zones’ have resulted in persistent fish kills and stressed or diminished aquatic ecosystems. Area draining to the Bay stretches from from New York to…

Plan For the Worst

Hurricane Florence had numerous effects on North Carolina: Flooded neighborhoods, ruined crops, damaged infrastructure, and submerged businesses to name a few.  All that water created what state officials were calling a 500 to 1000 year flood. Indeed, floods put portions of the Lumber, Cape…

Open the Flood Gates

Following up on the previous post, managers of Falls and Jordan lakes are nearing the end of their lake draw down.  For two weeks after Hurricane Florence made landfall, the flood storage usage of these lakes was in full effect as manages nearly eliminated…

Florence Flood Mitigation

We touched on the uses of Jordan and Falls Lake in a previous post.  One of those uses is currently evident in the aftermath of the recently passed Hurricane Florence.  The storm dumped between 6 and 12 inches of rain over the Falls Lake…
