Will Levels Keep Rising?

YES!

Lake Levels increased 6 inches last night - and another storm blew through our area - rising t0 778.74.

Inflow from Jefferson = 6170 cfs
Outflow at Indianford = 4170 cfs

Clearly, we are taking in more than discharging, but that is only half the story.

It takes time - 4-6 days - for all that water to pass through the tight constriction at the mouth of the river, east of Newville, STH 59 bridge, and Harbor Recreation. on its path to Indianford.

How do we know when levels will begin dropping? One indication is when the cfs numbers above flip.

Take a look at the MARCH and APRIL log sheets from this past Spring. You will see the snow melt and ice cap melt raised lake levels, but Indianford was still flushing more water than what was flowing in - so the climb was a slow, 0.5 to 2.5 inch per day increase. Not until the Spring rains hit frozen ground did we see the lake climb to 780.55 - where it crested.

The difference between August 24th (778..74) and March 24th (779.41) is 8 inches. However, the rise is occuring much more rapidly today.

This past Spring, it took 5 days to add those 8 inches to get to 779.41, and another 11 days to add another 8 inches.

When the levels begin dropping, we'll take a look at duration.
