Congrats on your first post!
Wow that is a big jump. Ought to work loose quite a bit of sediments and crud. Presumably, it won't change the stream biology much this time of year - unless of course there's something I don't know. Give it a few days to clear if it hasn't already and go fool em with midges and worms.
Funny, was just looking at the S. Platte Gauge at Trumbull. Looks like a heart monitor: USGS Current Conditions for USGS 06701900 SO. PLATTE R. BLW BRUSH CR. NR TRUMBULL CO
If you do go, let us know if you get into anything.
