Third Fork Creek
Water from Third Fork Creek flows into Jordan Lake. From there it flows into the Haw River and then to the Cape Fear River. This river is the only one in North Carolina that empties directly into the Atlantic Ocean.
The health and cleanliness of the watershed is reported in Durham’s annual State of Our Streams Report. In years when staff is able to take a wide variety of tests, the watershed is also given a score. Third Fork Creek was last given a score of 75 in 2016. This compares to a "C" letter grade. This is up from 74 in 2015.
Water from Third Fork Creek flows into Jordan Lake. Jordan Lake has recently had problems with algae caused by extra nutrients (such as nitrogen and phosphorus). The State has also created a TMDL (PDF), to help reduce the nutrients in the lake. Because of this, the City also tracks nutrients in Third Fork Creek.
Water Quality Investigations
In the 2016-2017 reporting year, staff found 59 pollution sources. These included:
- grease/cooking oil/food
- yard waste
- improper housekeeping
Stormwater Services encourages neighbors to discuss and discourage putting trash, wash water, grease, or other pollution into storm drains. Anything that goes into storm drains does not get treated and, in this watershed, eventually washes into Third Fork Creek. Citizens can also call the Stormwater Hotline (919-560-SWIM) to report water pollution.
Watershed Improvement Plan
The Third Fork Creek Watershed Improvement Plan is designed to prevent future water pollution and identifies special projects that can help repair current problems.
Dog Waste Stations
The City was awarded a grant to install dog waste stations in Durham parks. About 25 of these are in this watershed, many along the Third Fork Creek trail.
Residential Rain Garden Project
During the summer of 2012, the city continued the backyard residential rain garden project in the Third Fork Creek watershed, assisted by four students from the Mayor’s Summer Youth Program, and funded by an EPA 319 grant. The students determined appropriate sites by calculating rain garden size and evaluating percolation, and they constructed 24 rain gardens during the summer. Volunteers installed plants in the fall. These rain gardens capture runoff and help clean up pollution.
Forest Hills Park Stream Restoration
This project restored 3,000 feet of Third Fork Creek in a highly urban area. The stream banks were rebuilt. The new lower, curvy banks will help connect the stream to overbank areas called floodplains. A buffer of native shrubs and trees was planted. These plants will help treat pollution and prevent erosion. The restoration plan (PDF) and a recent project update are available online, although both documents are fairly technical.
For the latest update on this and other stream restoration projects in the city, check out the Stream Restoration Project Fact Sheet (PDF).
R.N. Harris Stream Restoration
Lead by the Durham Soil and Water Conservation District, this project restored almost 1,000 feet of Rocky Creek at R. N. Harris Elementary School. The project also included a large rain garden (also called a bioretention cell) that will help slow the flow of runoff reaching the creek and naturally clean the pollution in it. Teachers at the school use the site as an outdoor classroom for environmental education.
Water Quality Recovery Program
The Water Quality Recovery Program for Third Fork Creek carries out the state TMDL (PDF). The City prepared this plan in 2009 and submitted it to the NC Division of Water Quality. The City will submit updates with the annual NPDES permit report starting in 2010. Water from Third Fork Creek flows into Jordan Lake. Because Jordan Lake has a TMDL for nutrients, the Water Quality Recovery Program for Third Fork Creek also tracks nutrients.
There are many ways for you to help protect the health of Third Fork Creek. You can adopt a portion of the creek or volunteer to label storm drains. There are also 2 major stream clean-ups each year. Big Sweep is the 1st weekend in October and Creek Week is the last weekend in March. Email the public education coordinator for details.
You can also join one of the many groups dedicated to protecting the health of our rivers and streams. The Haw River Assembly is active in this watershed.
