The following data have been collected for a test week for a water supply reservoir.

$\backslash$table$[[,$Day$],[$Parameter$,1,2,3,4,5,6,7],[$Stream inflow $(\frac{{?}^3}{sec}),0,0\mathrm{.}25,0\mathrm{.}4,0\mathrm{.}5,0\mathrm{.}5,0\mathrm{.}2,0\mathrm{.}1],[$Stream outflow $),0,0\mathrm{.}15,0\mathrm{.}3,0\mathrm{.}2,0\mathrm{.}1,0\mathrm{.}1,0],[$City use $(\frac{m^3}{sec}),0\mathrm{.}3,0\mathrm{.}25,0\mathrm{.}3,0\mathrm{.}2,0\mathrm{.}3,0\mathrm{.}3,0\mathrm{.}3],[$Preciitation $($cm$),0,1\mathrm{.}55,7,2\mathrm{.}5,0,0,0]]$

The surface area of the lake is $65$ hectares

The reservoir surface elevation drop during the week:

$17\mathrm{.}5$

cm

The evaporation for the week was estimated to be

$7$

cm
