Is the overall park dump site open in March? (Now?) Or is if closed in till the water is turned on to the individual camp sites,which I read to be the first week of may?

It is open all year

I was there just a week ago and the trash was open the whole 2 weeks I was there

We are there right now and the dump and showers are open.

I don't know. We're from Illinois and camp there 2 to 3 times during the summer/fall months. It's inexpensive and in the center of all the sites and restaurants.

You just never know. I'd drive by and check it out. It was open late this year
