This is coming straight from the MN Darkhouse President Tim Spreck:

“In previous years, I wondered what had happened to spearing on Cass Lake,” Spreck said. “I was told it was a phony study that got the lake closed.”
“If we can make a case for this lake, we can make a case for others,” Spreck said. “This is the first domino, and it fell hard. Darkhouse association members and other spearers are responsible people; they are not out there to spear everything.”

This session the Darkhouse is letting it be known that they are trying to get other lakes lifted from spearing bans.

Here's a few reads from the Cass Lake Times:
