Wow - how big is this place?

I was wondering the same thing. It is 12,500 acres and 100 miles of
shoreline. it is the 5th largest reservoir in CA. Here is a aerial
photo of the lake full.

Fish heaven from the looks of all the submerged islands and the like.
Deep though - wow, 400 + feet?

On the plus side, it is still raining in N. GA, and the forecast is for
rain for the next two days. It has been years since we have had this
much rain in GA.

WHOO HOO!!!

Deep. Average. Oroville is down about 200' and there is still 4-450' of
water. Most of these lakes are in the foothills of the Sierras. so they
get some deep valleys to dam. Melones is known for the great Kokanee
fishing in the spring and summer.

How the heck to they keep the boat ramps or the marinas available with
100 ft. drop?

In the case of ramps, you grade and pour concrete to the water's edge when
the reservoir is on the way down. When the reservoir is on the way back up,
you have a fully functional ramp. In extreme cases, a temporary cofferdam
is built to allow construction/extension of the ramp.

In the case of marinas, they all float. Everything floats. Slips, ship's
store, restaurant, fuel dock, everything. The floating marina is tethered
to the ground by cables that are attached to large winches on the floating
docks and large anchors at the bottom of the reservoir. As the reservoir
rises and falls, the cables are adjusted with the winches. In extreme
cases, the marina may need to be relocated to deeper water. In that case,
everything is moved laterally and then re-secured to the bottom. It's done
that way every day in the western reservoirs and lakes. No big deal.

It is if you are the one moving the docks and marinas.

Last trip to Oroville, all the houseboats were tethered way out. There was
23' under me at my slip in the marina. Lake is supposed to go down another
140'. Berryessa built probably the nicest boat ramps anywhere when the lake
was being constructed. 8 lane pave ramps. Lake filled about 3 years
earlier than expected. If you mess up and roll off the end of the ramp, you
will probably be 300' underwater. at full pool. Oroville has all the paved
ramps out of water, and there are two low water ramps. Gravel ramps.
Actually nice ramps.
