Well, technically your response for Lake Mohave would apply to "What's downstream of this point?" So, I guess this will count as the correct response. The place I snapped the photo was actually Willow Beach, just downstream from Hoover Dam. Rafters put in at Black Canyon and then a leisurely day trip is to float down to Willow Beach or you can make this a nice two day float like Ellen "River Goddess" Ross did here...Vegetation looks right for somewhere near Las Vegas, but the water level looks way too high for Lake Meade. How about Lake Mohave?
