To find the overall change in water level for the last three years, we need to sum up all the changes in water level.

Year 1: -1 1/4 inches
Year 2: +3/4 inches
Year 3: -1 inch

To add these values together, let's convert the fractions to a common denominator. The common denominator of 4 and 1 is 4.

Year 1: -1 1/4 inches = -5/4 inches
Year 2: +3/4 inches
Year 3: -1 inch

Now, add the values together:

(-5/4) + (3/4) + (-1) = (-5 + 3 - 4)/4 = -6/4 = -1 1/2

Therefore, the overall change in water level for the last three years is -1 1/2 inches.
