Clean-up work on the remains of the fire at The Dalles Marina in early July will start on Monday.  Port of The Dalles Executive Director Andrea Klaas says details are still being hammered out, but she expects the work to be finished by the end of next week.  She says the availability of qualified contractors to do the work was hampered by other jobs taking place during the window for work to take place on the Columbia River.  Still to be removed from the Marina are eight boathouses and two boats that were damaged in the fire.
