  We report the first measurement of differential and total cross sections for
the ${\gamma}d \to K^0{\Lambda}(p)$ reaction, using data from the CLAS detector
at the Thomas Jefferson National Accelerator Facility. Data collected during
two separate experimental runs were studied with photon-energy coverage 0.8 -
3.6 GeV and 0.5 - 2.6 GeV, respectively. The two measurements are consistent
giving confidence in the method and determination of systematic uncertainties.
The cross sections are compared with predictions from the KAON-MAID theoretical
model (without kaon exchange), which deviate from the data at higher W and at
forward kaon angles. These data, along with previously published cross sections
for $K^+ {\Lambda}$ photoproduction, provide essential constraints on the
nucleon resonance spectrum. A first partial wave analysis has been performed
that describes the data without the introduction of new resonances.
