A telescoping weir for the controlled drainage of contaminated bodies of water, such as confined disposal facilities (CDF), which selectively releases only the relatively clean water while leaving behind a contaminated portion. The weir includes a foundation that is anchored to the bottom of the body of water and connected with a discharge pipe, a cylindrical telescoping portion connected with the discharge pipe and extending upwardly from the foundation and terminating adjacent to the surface of the body of water, and a set of mechanical jacks for selectively extending and retracting the upper end of the telescoping portion above and below the water surface in order to selectively drain a top layer of clean decant water therefrom.
