papaslap,

I've been there once this year and many more times in the past few years.
Same sad story how ever. The basin is still full of silt and you only have a little time either side of high to get a boat in or out. last year the caretakers thought Merrill and Ring would have it dredged for this year. Doesn't seem to be the case since they split this year. Apparently disposing of the sludge was going to be high dollar.
Anyway silverking has been full or close to it in the past few years from august through the end of september. As it was for the king opener the 5th of july this year.
I have the phone number around somewhere and if I can find it I'll try to get it to you.
