Pond Boss Forums POND CONSTRUCTION Selecting a site How much Water do you thinkI could gain?(pic)

I dont get much run off in my leaking pond so I am thinking about putting gutters on my house and garage that you see in the back ground of this picture.It is a 24x42 garage.Dont think it would be a tough job to get the gutters on and piped over to the pond.Would it be worth the expense to put gutters on and pipe it to the pond?Would I gain much water from them?

For every inch of rain you get the pond would get 628 gallons of water from the roof assuming all of the water runs off.

628 gallons is insignificant when an acre of water one inch deep has 27,152 gallons of water.

That's a cool idea though!! And it's not going to hurt anything that's for sure. It may help in those times where you don't get that much rain. Think about it. Right now all your getting is the rain that falls into the pond at the moment from above. Well if you put gutters on your garage and pipe it then your getting all that water as well. Even if it's just a few hundred gallons it's still fresh water that normally would not be used for anything why not use it!!! What if you get 2 or 3 days worth of rain then your piping all rain into your pond that sounds good to me!!

I believe what Chris is saying is that it is not worth the expense because the amount of water added to the pond would not be significant. Here's a bean counter's run down....

In another thread you mentioned your pond is 3/4 of an acre. Lets assume that at the lowest your pond averages 4 feet deep (I have no idea what your pond averages at the lowest so I'm making an assumption here for math purposes). So .75 acre at 48" deep multiplied by 27,152 gallons per inch = 977,472 gallons in your pond.

If you had a six inch rain event and used Chris's 628 gallons per inch of rain then you would have added 3,768 gallons of water to a pond that contains almost a million gallons of water. So you would be adding only about four tenths of one percent of water to the pond.

It's not that this is a bad idea, it's just that if you are asking if it would be beneficial from a cost versus benefit standing point then the answer is probably not.

There, have I muddied the water enough for you now?

As an also and besides, here in California some folks are beginning to use water reclaimation systems that collect rain water from house gutters and then use this water for plant watering purposes.

From the picture, it looks like the pond is downhill from the garage. If so, (some of) the water that lands on the roof is making it to the pond now.
