Chelker Reservoir is a man-made lake in North Yorkshire, England.

It lies in the parish of Draughton, immediately north of the A65 road, between Skipton and the village of Addingham.

It was put into service in 1866 and serves the Bradford area;[3] it is currently owned by Yorkshire Water.

In 1992 a wind farm, the third-ever in the United Kingdom, was erected on the north side of the reservoir.

The wind farm consisted of four two-bladed turbines which generated 1.2MW and went online in December 1992.
