Welcome! First of all I'm no pro, so take everything I say with a grain of salt. Lol! Do you know how much water shed you have? You may want to try to get it in before spring, so the spring rains can help fill it. Also spring rains can make things to wet for digging. If you have a very large water shed area, you may be better off waiting til after the spring rains, so you can get some grass growing to keep things from eroding. Maybe someone that knows more than me will put their two cents in.lol!
