January 2010 – Dredging continues after DNREC received an extension from the U.S. Army Corps of Engineers and the State of Delaware to dredge this year until April 15 in an effort to complete the project before the upcoming boating season. That date will also coincide with completion of the project, it's greatly anticipated. Project manager Charles Williams explained that a third confined disposal facility had been secured for dredge from the canal and, once constructed, it will expedite the dredging process. The facility was actually secured last November, but weather-related issues precluded its construction. Currently, the dredge crew is making only about 50 feet of advance a day, primarily due to the use of a booster pump and the pumping distance to the disposal facility presently being used. The new disposal facility will not require use of a booster pump which is expected to double the daily advance rate. Mr. Williams also stated that he has been involved with the dredging of the canal in some capacity or other since 1984, and would like to see the project completed as soon as possible.
May, 2010 – With a harsh winter deterring completion efforts, dredging continues in the Assawoman Canal, through an extension granted by the regulatory agencies allowing for work to continue through May 28.

June, 2010 – DNREC receives State Wetlands and U.S. Army Corps of Engineers permit extensions through July 31, though the department is on task to have the canal dredging project completed by that date, with currently less than a 1/2 mile of dredging remaining.
