Question $18(0\mathrm{.}5$ points$)$

Using Figure $2,$ which of the following is$/$are true?

Figure $2.$ Gauge Height vs$.$ Discharge of the Red Cedar

River

The maximum discharge is just over $4000$ cubic feet per second $($cfs$)$

The maximum gauge height represented is over $9ft.$

Discharge is roughly $500$ cubic feet per second $($cfs$)$ when the gauge height is at

$4\mathrm{.}5ft$

Discharge increases as gauge height increases

All of the above are true
