I've been reading the talk of the water levels on the slope being low, since I'm headed up there next week I started doing some investigating to see how out of the ordinary they were. I started on the internet at: http://aprfc.arh.noaa.gov/ak_ahps2.php which is the river water levels around the state from the NWS River Forecast Center. Then I went to the chart for the sag as measured at Pump Station 3.
Historical data isn't available, so I called them and spoke with a very helpful person who provided me with previous years data and assisted in interpeting some of the other charts.
For today's date the sag is at 15.21 ft
This day in 2006 the sag was at 15.61 ft
This day in 2005 it was 15.01 ft.
Of course the river isn't 15 ft deep, they just use a baseline that is above 0 for measuring depth.
So I'm not saying boating is any easier right now, it just seems like the water levels are close in line with the last three years.
