Tim and Pam Brady of Bartram Park, Colo. celebrated their 25th wedding anniversary on Wednesday.

But for Tim, the celebration has been tempered for the last five years. A volunteer with the Big Thompson Canyon Fire Department in 2013, Tim was in the thick of one of the worst natural disasters in Colorado history—torrential rains and massive flooding that devastated lives and property just off U.S. 34 near Loveland.

For a time, Tim Brady was the only first responder on the scene. Speaking to Colorado Matters, Brady recalled being alone to deal with the chaos.

"I was the mayor, the sheriff," he said.

And while he was credited with saving more than 100 lives, Brady says what he thinks about more are the two area women, Patty Goodwine and Evelyn Starner, who died during the flooding.

"I wonder if there was more that I could have done (to try and save them)," he said. "There are just a lot of would've, could've's."
