This Joe guy seems to be a very interesting character, and I can see from all the ominousness that this has promise to it.
I'm by no means an expert or anything...but here's just some things I would change:
a fear from them
a fear of them
He had seen movies and such of things of the dark that would always attack people that ventured out into the darkness to see just what that little noise was, or what that shadow that moved across the tree-line all fast and mysterious really was. He had never taken this fully into retrospect that he had been doing the same things his whole life.
This part seems kind of unwieldy. Maybe take out 'and such', change the second 'of' to 'in'. I'd also maybe take out 'or what that shadow that move across the treeline all fast and mysterious really was' cause it's a little unnecessarily wordy. Also, 'He had never taken this fully into retrospect' is a really weird-sounding phrase. Change it around to something like 'He had never made the connection that he had been doing the same things his whole life' or 'He had never fully realized that he'd been doing the same things his whole life.'
The sun was just rising above the trees on the east side of his lake. The side the dam was on.
Maybe put a dashy-thing there instead of a period--it's a broken sentence.
He had no idea what this great morning would lead to the following night. There was no sign of such a horrid night anywhere this great morning
Really redundant, and especially because you've already served up the ominousness in the previous paragraph. Either take out one of the sentences and reword the other to be a lot more subtle, or take out both.
Good morning hunny
'Hunny' is Winnie-the-Pooh spelling, and even though Winnie-the-Pooh is my personal hero, you might want to change it to 'honey'.
The weather man had said the day was going to be partly cloudy with clouds clearing by midnight with a half moon for the rest of the night
The weatherman doesn't usually tell me that there's going to be a 'half mon for the rest of the night'; if I want to know what part of the cycle the moon is in I either have to figure it out myself or consult a calendar, some of which have the moon's cycles on them.
He continued to watch the rest of the news until he decided the dew was off the grass and it was time for a fresh cut before the day became to hot.
He decided the dew was off the grass?

Maybe 'he decided that he'd waited long enough for the dew to disperse' or something.
He was done around noon and decided it was time to go in for lunch. His wife had left him a ham sandwich on the kitchen counter for his lunch.
Maybe combine these two: 'He was done around noon and went in to the kitchen, where his wife had left him a ham sandwich on the counter for lunch.'
Also, when you use dialogue, you normally give dialogue its own new paragraph:
He had finished drinking his coffee and turned to go back inside to put the cup in the sink. His wife had just awoken and was standing there fixing her cup of French Roasted coffee.
“Good morning honey,” he said as he leaned over her shoulder and gave her a small kiss on the cheek. Her name was Sarah. She had loved Joe ever since she met him her sophomore year of college. He was her dream man in every aspect she could ever think of.
“Good morning baby, how was your sleep?” she answered.
"Great," he said, as he put his cup in the dishwasher.
“I need to go to town today and get some things for Joey’s school project he has for science class,” she said.
Anyway, that's all I can say for now...

Other on the board will probably be more helpful. [/i]
