Clanwilliam Dam

Contour Charts

The Lowrance SA Inland chart only has the dam outline, while the sediment is average at best, but does give a guideline if you know what to look for. The Insight Genesis charts also have very little coverage and that too is average at best. The HD Charts have very limited contours but are quite accurate, but when combined with the high definition imagery, serve as quite adequate.

The images below show how HD Aerial imagery assists in improving accuracy when compared to average contour charts. The charts also show how the contours are great showing average depth, but lack detail often required for fishing.

Satellite v.s HD Aerial & Elevation Charts

The images below show how HD Aerial and Elevation imagery assists in improving accuracy and perspective.
