Couch took it upon himself to build a suction dredge at his marine ways in Grant. He also hired Charles W. Sembler to dredge out the cut. No sooner was the inlet open in 1918 than it was again filled with sand and debris. There were a number of influential citizens in the area who were steadfastly opposed to opening the Sebastian Inlet. Among them were grove owners such as A. B. Michael of Orchid. Michael was opposed to it for several reasons. One, he saw opening an inlet to the ocean as something that would forever change the fragile ecology of the Indian River Lagoon. At that time it was almost a body of fresh water. He was also concerned that the influx of salt water would ruin the fresh water wells essential for his groves. Cattlemen on the mainland nearby also shared a fear that their fresh water wells would be ruined, but the most powerful opponent to the opening was by far Henry Flagler's Florida East Coast Rail Road that feared salt water in the lagoon would mean teredoes in the pilings of their rail road trestles that crossed the areas fresh water rivers. At any rate, it wasn't but a couple of days after the Sebastian Inlet was opened that someone organized several boatloads of men from the Narrows to Ft. Pierce into an Inlet destruction crew. One evening they loaded lanterns, shovels, saws, pick-axes, dynamite and chains, maybe even a mule or two, into boats and headed to the newly opened Sebastian Inlet. There they cut cabbage palms and any other tree they could find, dragged them into the cut and placed a lot of dynamite along the banks. Once the dynamite was set off it blew sand into the inlet sufficiently to plug it up. Couch committed another dredge to the project and work continued through the winter, even past the December 31 expiration date of the permit. Before long word of the projects continuance past the permits expiration date reached the War Department and this agency was not amused. Every one of the Sebastian Inlet Association's board members and the dredge crews found themselves threatened with arrest if the work wasn't halted promptly. With the two dredges still at work Couch and some other influential citizens set out for Washington, D.C. where they approached Senator Duncan U. Fletcher and lobbied him to work
