From playing with that earlier, I remember that it is not that good outside of coastal ocean areas. I think it simply adds higher water to ocean level, so if you have a river it is upstreams often already higher then the ocean is (thus explaining the water running downstreams). So it is not a realistic simulation of rivers increasing.

That's a different Indian Point, in Maine. The Indian Point power station is on a sand bar in the Hudson river on the east side, in Buchanan. There's nothing secret about it--plenty of places where you can get good photos.

FEMA publishes flood maps for the entire country; here's the one for that area.http://map1.msc.fema.gov/idms/IntraView.cgi?ROT=0&O_X=7044&O_Y=3622&O_ZM=0.077294&O_ SX=1088&O_SY=560&O_DPI=400&O_TH=55896125&O_EN=55874632&O_PG=1&O_MP=1&CT= 0&DI=0&WD=14400&HT=10350&JX=1227&JY=620&MPT=0&MPS=0&ACT=1&KEY=55 895597&ITEM=1&PICK_VIEW_CENTER.x=552&PICK_VIEW_CENTER.y=303&R1=VIN

It's a viewer and might not work right especially over a slow link. Basically it shows the "100 year" flood zone, more properly called the 1% annual recurrence probability event zone. The flood zone doesn't impinge on the nukes.

These maps are made using field data collected over the years by on-site measurements, then calculated using the HEC-HMS and associated hydrological simulation programs.

Normally, flooding is caused by rainwater draining from higher elevations, and while the modeling tools can accommodate the effect of blockages that cause reductions in downstream flow, I don't know if they actually account for upstream flow from a storm surge.
