The line $y=2000$ is a horizontal line located $12$ units beneath the point $(1000,2012)$. When a point is reflected about a horizontal line, only the $y$ - coordinate will change. The $x$ - coordinate remains the same. Since the $y$-coordinate of the point is $12$ units above the line of reflection, the new $y$ - coordinate will be $2000-12=1988$. Thus, the coordinates of the reflected point are $(1000,1988)$. $\boxed{(1000,1988)}$
