Variation of water depth $(y)$ in a gradually varied open channel flow is given by the first order differential equation
$$\dfrac{dy}{dx} = \dfrac{1-e^{-\frac{10}{3} \ln(y)}}{250 - 45e^{-3\ln(y)}}$$ Given initial condition: $y(x=0) = 0.8m$. The depth (in m, up to three decimal places) of flow at a downstream section at $x=1$ m from one calculation step of Single Step Euler Method is ___________
