I do have the grate type or slotted plate sections that Agri-drain makes and have tried them with minimal clogging. I have been using them in the summer when we don't have as much rain, but in the spring I have used the standard style plates to allow the water to spill over and evacuate into the drain faster.

Has anyone ever designed a larger screen structure to put around the yellow cage at the end of the drain? If so it would be interesting to see some pictures or to know if that would even work. To me it seems like if you could build an enclosure using finer screening and place it around the drain it would reduce the number of fish that could enter the drain. I realize that the potential for clogging would exist but I think if a finer screen covered a much larger area, it would not be as likely to clog?
