Hi guys I stumbled on this site some how and I love it. A lot of my questions have been answered already. Here is my thing. I just purchased a 5 acre lot in Minnesota just west of Minneapolis. I want to build a pond about 2500-4000 sqft for a few reasons. Hold water to supply my apple trees and sweet corn with water, swim,landscape purposes and raise trout for fun. I have read that the temp needs to be kept in the 55-65 degree area, but is that for rainbows or brown trout? Is my pond big enough. How deep should I make it? I can get about 8-10 feet pretty easy. How many fish can I put in it? I will use a plastic linner, is this ok? Thanks in advance for any help I recieve.
