12.20 Judging from what you learned from information in Figure 12.19A in chapter 12, how might one seal a leaking stock pond? Hint: We’re talking three steps here, with steps #1 and #2 being the draining and restoring pond water. Answer: The steps that could be taken to seal a leaking stock pond would be Step #1 drain the pond, step #2 restoring pond water, and step #3 would be to add an impermeable liner that would stop the water from leaking into unsaturated soil. 12.21 Examine Figure 12.22. At a glance several ponds might be mistaken for stock ponds. However, there is evidence indicating that the large pond at coordinates P-5 is surely a sinkhole. What is that evidence? Hint: The evidence appears in the relationship between the pond and a man-made feature. Answer: Based on the picture from Google Maps it appears that the road was straight but when the sinkhole occurred it took out that portion of the road and it had to be rebuilt around the sinkhole. 12.25 Do water levels in these three lakes (as well as others) appear to be governed by the vagaries of spotty rainfall and random surface drainage, or do they appear to mark systematic elevations on a water table?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
