Goulding Creek.net is intended as a community resource, starting as a depository for maps and documents, images about the watershed and as a forum for new and ongoing matters of interest. We intend this to be a friendly site to which anyone can contribute materials, opinions, and questions. A place where you can find out what has already happened, what might have been suggested, what needs to be done, and who to talk to for additional information. Please suggest items you would like to see on this site and I will try to provide them. Or send them to me and I will add them. I can probably work with any medium or format.

A draft of a map of the Goulding and Moss Creek watersheds has been added. It shows roads, streams and lakes, and parcel boundaries.

The Goulding Creek Watershed Weblog is up. Please visit, add comments to the posts, and register there to begin posting your own contributions. There will shortly be a guide to help those not yet skilled in the practice.

There has been some progress in more accurate placement of lower Goulding Creek and lower Moss Creek on the Parcel Map. The newest version should be linked to the image at Maps and Documents.

This was a known problem and had to be solved to accomplish a more immediate goal: accurately understanding where exactly the limits were of the Inundation Zone predicted by the NRCS to result from a major failure of the Lake Oglethorpe Dam. The study was done in 2005 at the request of the Lake Oglethorpe Association. Thanks to Steve Johnson for providing the report and I hope I used it well and will be glad to provide intermediate images for those who want to work with it. I think I have positioned the Inundation Zone reasonably accurately. The map is still incomplete, the Inundation Zone is calculated to just before Barrow Creek enters the Oconee River. Don't know what to make of it yet. See the Dam Failure Analysis page for complete details.

The page dealing with the August 2007 request to LOA is now up. It contains a Table of documents, which should be filled in the next few days. I also have a commentary, a request for more documents, and a request for contributions to be mounted there or independently on the Weblog on how to proceed.

Predicted levels, perimeters, areas, and volumes of pools in Lake Oglethorpe, each maintained by a particular overflow or exit device, are now available at Lake Oglethorpe Pool Areas. They were calculated in order to predict the results of methods that the LOA might use if it wanted to hold flood water rather than, as present, merely pass it downstream. Not encouraging results.

Unexpectedly, the volume of the Flood Pool is calculated to be 1.4-fold larger than the volume used by the NRCS to calculate the Inundation Zone if the dam should fail when it is holding a Flood Pool. I do not know how to scale their result if the larger volume is assumed for the Flood Pool, not knowing if the Inundation Zone is limited more by the appature in the dam or by the volume of the pool behind it. Something else to discover.

The beginnings of the Map Archive are up at Maps along with some initial comments about which formats to use for particular printing or processing needs. I hope all maps and their derivatives will be listed here. Some will also be in Subject Pages.
