I'm in Minneapolis MN. My (former) manager gave me the delightful task of naming my raise, as long as I could justify it within market range.

I keep a good ongoing relationship with multiple recruiters, so I simply forwarded them an updated resume and asked them, for the job I'm doing, with the skills I have, for local market, what's my range? Easy and someone else does the work.

3 recruiters agreed that the (typical) Minneapolis range for senior level swings from 90 to 115. (BTW I didn't get the raise anywhere near the top end of the range, but the questions to recruiters did get me a a job offer at that point!)

Definately, know your worth. If you're not there by salary then it's the other intangibles that have to make up the difference. I actually didn't take the highest offer, I took a lower offer where the intangibles are worth the salary difference to me.
