Hey all, I have a core trench depth question...
Soon will be building a 1 acre pond on roughly 8 percent slope, so it will be fairly long and narrow. I am very familiar with the construction process, but would like clarification on trench depth. Seems that many mention that bottom of trench needs to be 2 feet below the bowl bottom. Others say just dig into virgin ground a good four feet and call it good. Is that two feet mentioned above, level with the bowl bottom or does that two feet follow the 8 percent slope? If I am following the 8 percent slope, then I could easily be over 8 feet deep on the core trench (depending on how deep I cut on the bowl)
I just don't want leaking water following the natural strata and moving beneath my core trench.
How do the rest of you interpret the rules of thumb for core trenches? Thanks in advance...
John
