Water Level is Dropping, Iquitos Peru
You might be interested to know the water level is now dropping one foot per day. My sonar shows the water level in the flood plane of the Itaya River dropped thirteen feet in the last two weeks.
We moved the boats to slightly deeper water a couple of days ago. Early tomorrow morning, I plan to move the boats around to the other side of Iquitos at the Hunting and Fishing Club on the Nanay River.
In two more weeks, farmers will be planting corn and watermelons where my boats are now. Soccer games will last till dark.
The Amazon River can rise and fall approximately forty feet every year. The water level usually starts to come up in October or November, crests in January or February, and stays very high till May.
That dramatic rise and fall has little to do with how much it rains near Iquitos. A ten year average shows that Iquitos receives approximately the same amount of rain every month.
The “dry season” is a myth. June is considered to be in the middle of the “dry season”. During one 10 year average, more rain fell in June than any other month.
The Amazon River rises and falls in response to seasonal rainfall on the east slope of the Andes, as well as snow, and glacial melt.
The high water season and the low water season affect the way we live, from building houses on balsa logs that float, or on stilts above the expected high water level. We retie our boats hundreds of times per year and move them a dozen times because of rising and falling water levels.
On the chart below the green line represents the record high water levels for each date, the red shows the record low water levels, yellow is the average, and the blue line is the actual water level from a few days ago.
