Q

The Gage at Red River Landing reads 22.2 feet. The low water reference plane for Red River is 10.6 feet. How many feet is this above the low water reference plane?

🔍 Key Concepts

• River gage reading vs. reference plane – what does each number represent? • Simple subtraction when comparing a current level to a reference level • Keeping units consistent (all in feet)

💭 Think About

• Ask yourself: Is the gage reading the current water level, and is the low water reference plane a baseline you compare it to? • What single arithmetic operation lets you find how much higher one level is than another? • If you imagine the low water reference as 0, how far above that would the current gage reading be?

✅ Before You Answer

• Confirm you are finding the difference between two levels, not adding them. • Carefully subtract using both numbers given: 22.2 and 10.6 (in feet). • After you do the math, compare your result to the answer choices and make sure the magnitude makes sense (it should be less than the higher of the two numbers).
