Raritan River Gauge height

[tjc76]

Hello everyone,

I'm looking to fly fish the Raritan main stem from my canoe, primarily targeting smallies.

I have very limited experience on the Raritan, and am looking for input as to which gauges people reference, and at what gauge heights is the river too low to float, and what gauge height is too high to safely float.

Thanks, tight lines,
