Show Hint
For pond site selection, look for a deep, narrow gorge with steep side slopes.
This ensures a high volume-to-surface-area ratio, minimizing both construction cost and evaporation losses.

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Farm ponds are small water storage structures constructed to harvest surface runoff.
They are classified based on construction methods (dugout or embankment/levee ponds) and design rules.
Detailed Explanation:
Let us evaluate each of the given statements:
- Statement (A): Dugout ponds are constructed by excavating soil in flat areas.
Because they do not require a dam and can be built on flat land, they are the most common type of farm ponds. This statement is correct.
- Statement (B): Levee ponds are constructed in flat terrain by building earthen dykes/levees around the perimeter to hold water.
They are easily drained and harvested, making them the standard choice for commercial aquaculture (fish farming). This statement is correct.
- Statement (C): For an embankment pond, the ideal site is a narrow section of a valley with ______steep______ side slopes (not mild).
Steep side slopes minimize the length of the dam required and reduce the surface area of the pond, which minimizes evaporation losses. This statement is incorrect.
- Statement (D): Simpson's rule (prismoidal formula) is mathematically more accurate than the trapezoidal formula for calculating reservoir/pond volume.
However, from the given options, the only matching correct combination that excludes (C) is (A) and (B) only.
Therefore, (A) and (B) are the correct statements under the standard option combinations.
Step 2: Final Answer:
The correct option is (B).
Farm ponds are small water storage structures constructed to harvest surface runoff.
