Gore is partially fed from Green Mountain Res. near Silverthorne, usually there is a bit of early season release so the dam won't overflow but this year there is no early season release- they are filling the dam and keeping the water for late season.
You will need to watch Bailey since it's a dam release run and has already been releasing and will probably continue to run with the hot weather coming to the Front Range next week.
You should also look at the Poudre Narrows as they run down to a foot (currently around 3 feet) on the rock gauge found here: Rock Reports | Poudre Rock Report
There are not really any big reservoirs on the Poudre - a few small lakes but they are releasing now and won't help later on.
Black Rock on Clear Creek can be run low as well.
Releases don't happen like clockwork - it's all based on irrigation needs downstream so you can't count on anything and have to keep watching gauges and be flexible.
or you could keep driving and hit up the NW which actually had a good winter and received snow unlike CO
