Raritan river fish ladder numbers:

[AndyS]

Yes American Shad do rely on one thing, WATER !! Dismal spring rains do play a large part on migration on the Raritan river as it is a very wide and for the most part a shallow river.
Graphs and charts were also presented showing the comparison between fish movement and water gauge height.
Could be a while for trout and bass numbers and they are still working on 2017 fish counts.
