The volume of the swimming pool can be calculated as follows:
$V = lwh = 23	ext{ ft} \cdot 23	ext{ ft} \cdot 3	ext{ ft} = 1,977	ext{ ft}^3$
Since there are 7.48 gallons in a cubic foot of water, we can convert the volume to gallons:
$V = 1,977	ext{ ft}^3 \cdot 7.48	ext{ gal/ft}^3 \approx 14,817	ext{ gal}$
Rounding to the nearest gallon gives us a final answer of $\boxed{	extbf{(C) }11,871	ext{ gal}}$.
