Take a look at Redrobes' Most Excellent tutorial about how to get your rivers in the right place - it should be stickied near the top of the tutorial forum. But another thing other than the slight "lying on top of the overall texture" issue, is that you're mapping a continent - your intent to show the width of the rivers varying results in them looking to be what, fifty miles across in places? SOmething a bit bigger than you intend, anyway. It's a tough trick, to show variations in a river - at this scale a satellite photo might show only a pixel or two of width, so it's pretty normal to generalize when symbolizing the watercourses: wide enough to be discernable, but narrow enough to look like a long river. Sinuous looping in the lower reaches of a flatland river has to be exaggerated ... subtly, and probably has to be shown in far fewer number than the real river's convolutions. <shrug> - it's a tradeoff.
The suggestion to incise the river into the terrain by masking the surrounding texture must work - I see it on a lot of Photoshop maps (refer to previous assertion of PS naivite on my part), but even that needs to be done with a light touch - going ahead and beveling the land to further emphasize the channel works best on large-scale (equals small area, remember) maps; the impression on a continental scale starts to be "vast canyon" rather than "river banks".
