Re: How long does it take for a new pond to produce decent fish?
They did this, a few years ago, when I still lived in the "BIG CITY" of Portland. Out, in the "Burbs", they built these "Yuppie nesting places" covered with too expensive homes and almost, all, had a "neighborhood lake/pond".
Basically, they scooped out a lake with a loader and backhoe, let it rain and in rare cases, ran the fire hydrants in them, until they filled up. Well, with NO proper aquatic vegetation, more importantly NO way to exchange water aeration, within a year they had themselves a fantastic mosquito breeding farm operation going so bad, the city made them fill in many of them and others were forced to install "high volume aeration fountains", to remedy the problem.
They tried fish, in a few, but in limited numbers and in no time the raccoons, herons, seagulls, ducks,geese and neighborhood cats cleaned them out. The Yuppies also started dumping their goldfish in them, THAT became interesting in a few cases!!
They were all, about 1 to 3 acre lakes, too, not mere "farm ponds" or "overgrown fountain ponds".
Also, since there was no other bodies of water within miles, come migration time these new lakes and ponds, were so "covered in ducks and geese" not only could you not see the water's surface, for the bird bodies, you couldn't walk within 25 yards of shore, without "sliding in green doo-doo, straight into the water!! (Or, at the least, slide onto the tops of a 1,000 ducks and geese!) The stories, in the local paper also described; "The near, deafening noise of a thousand squawking ducks and geese, at all hours, day and night!"
I'd call my County Extension Office, locally, and ask them what they think these lakes may support and when. Or if they'll sustain vegetation, and/or, life of any kind, that you won't need "OFF" to protect yourself from!?!! They should come look at these new lakes free of charge and at least give you an idea.
I don't know, about your neck of the woods but in Oregon, the penalty for "transporting live game fish, from one body of water to another", is a $1,500 fine and the loss of your fishing license for 3 years. If you have any tackle in your car/truck, when caught too, they also confiscate that as well and you DO NOT get it back! Unless, of course, you go to the once or twice a year "State of Oregon Evidence Auction" and bid on your own tackle, to get it back!?!
