Highest Water Level 2009
Typical of the Amazon River system is a forest type (igapˇ and vßrzea) which is highly adapted to survive long periods of submergence. Following the rainy season in the Andes, the water level of some rivers (such as the Rio Negro and Solim§es at Manaus) may rise as much as 15 Meters (50ft) on an annual basis, and the water covers large areas of forest for up to eight months.
Travelling by boat at high water allows easy observation of wildlife in the flooded forest. The animals are concentrated at the treetops, witch are not just accessible but almost at eye level.For nature observation by boat, such as Amazon Clipper Cruises provide, the period from the end of the rainy season, March onward, is the most fascinating.
