Here is my weekly weather quiz question for the last time. What is “Deep Percolation Loss?” Here is the correct answer. Deep Percolation Loss in hydrologic terms, is water that percolates downward through the soil beyond the reach of plant roots. I’ll have a new weekly weather quiz question for you starting Monday. The first person to post the correct answer as a comment on this page will win a week of free personalized weather forecasts tailored to your needs. Good luck.
