Can someone tell me why the balance is 0

./src/zcash-cli getinfo

{
"version" : 1000250,
"protocolversion" : 170002,
"walletversion" : 60000,
"balance" : 0.00187270,
"blocks" : 12278,
"timeoffset" : -8,
"connections" : 8,
"proxy" : "",
"difficulty" : 347762.92819983,
"testnet" : false,
"keypoololdest" : 1478397135,
"keypoolsize" : 109,
"paytxfee" : 0.00000000,
"relayfee" : 0.00005000,
"errors" : ""
}

./src/zcash-cli z_sendmany "$TADDR" "[{\"address\": \"$DEPO\", \"amount\": 0.00177270}]"

./src/zcash-cli getinfo

{
"version" : 1000250,
"protocolversion" : 170002,
"walletversion" : 60000,
"balance" : 0.00000000,
"blocks" : 12281,
"timeoffset" : -8,
"connections" : 8,
"proxy" : "",
"difficulty" : 344983.56224021,
"testnet" : false,

}

How can I tell where 00010000 was spent? I'm guessing fees.

Yep! That looks like fees.

It costs 0.0001 to create a z_sendmany transaction.
