Thanks Bob-O! I don't mind pond weeds too much since I kinda grew up with weedy ponds anyway. As for "gentle slope", I sort of thought that some areas would slope from grade level to 10' over a span of 30' but, because of the excavation I'll have to do anyway, some places will drop from grade level down to 10' over a span of only 10' or less. Lowest area(s) to be about 15 to 20 feet. It really will be mostly a dug out, and compacted, hole in a leveled off area... one heck of a LOT of dirt/sand/rock to move but, I got places to put it!
