Pond Boss Forums POND CONSTRUCTION Selecting a site is this a good idea to build a pond here

we bought a house a couple months a go and found out after that what we thought was neibors side yard was ours only thing is its seperated from the rest of yard with a large deep stream i was wondering what yalls thoughs was for putting it under water and if its even big enough to worry with the size of the lot is 100 by 100 and is clear besides small pines someone planted would like to find a use for it because the way it is we get no use from it besides the neibors think its a great place to dump there limbs another question is water supply the stream is about 10 or 15 below running strait along side could i use a pump to fill the pond from the stream keep in mind i dont reaally have much knowledge with all this so your guidence would be more than appreciated
