The extra fill will give us a firm base over the entire area, up untill now we couldn't mow anywhere near the stream without getting bogged down. If the whole area is mowable it will be much easier to look after.
It would be nice to spread some top soil and plant some grass but that will need to wait till the spring now.
It was pleasing to see our earthworks haven't adversly affected the stream life. Looking along the stream last night I saw numerous fresh water crayfish in the area where we have been working.
