9/6/2018 when Robert G. Martin Lake stops draining into Pond Run in Hamilton, NJ, all of the fish in the first pool below the dam die from hypoxia.

Always best to inform NJDF&W.

When I reported it to NJDEP by email, I got the same automated "out of the office" reply from Dr Jan Lovy that I got when I reported the Carnegie Lake 4/13/206 fish kill. All of the dead fish got washed downstream after the rain and the lake is draining again. I reported the fish kill to Hamstat but didn't get a reply yet. Wouldn't a screen around the outlet prevent the problem?

No, unfortunately, a screen wouldn't help at all. It would only serve to clog the outflow with debris. Most of those fish migrate upstream from below, not by falling down from the pond.
That situation has been occurring there for nearly half a century, basically ever since they built the lake. However years ago the situation was not nearly as bad since much of the present development in the watershed upstream of there didn't exist back then. Now there is so very little sustenance flow during dry periods that the lake stops draining far too frequently. If we hadn't been having the wet summer we've been having this fish kill would have happened at least 2 months ago.
