b$)(17$ pts$.)$ The New York State Department of Environmental Conservation is imposing a

limit of $0\mathrm{.}02$ mg$/$L mean epilimnetic TP concentration for Onondaga Lake. Calculate the

weighted contribution of each natural creek and METRO $($mass of TP coming from each

creek to the mass of TP in the lake$).$ Based on the weighted TP mass, which inflow$($s$)$

should be regulated in order to achieve $0\mathrm{.}02$ mg$/$L TP in the lake? You are free to choose

which inflow$($s$)$ to regulate
