You just missed it (the longest front range boating season in a while).
Where'd you move from?
Front range IV != IV in other states ... think manky, creeky and continuous. Going from an Idaho or W. Viriginia Class IV and jumping on Lower Boulder Canyon with decent flows (which is rated a IV to IV+) may scare your socks off (it did me). I'm not saying its harder or trying to start a ratings war, its just different sort of water with intimate proximity to a lot of sharp blasted rock... The Ark has nicer rock and is higher quality than some of the roadside IV closer to Denver/Boulder.
A couple laps on Middle Poudre Narrows may be worthwhile intro to front range IV boating for you, and will run for another week or two (above 1.5 or so). Its sandwiched between some V's so pay attention. If its above 2 feet, run Pineview through Bridges Take-out (BTO) to add a few hours and make the run a bit more worthwhile. If it holds around 2.5 feet, you can do a full steven's down and still have a lot of fun. The guage: Poudre Rock Report
On the Ark, people run Numbers, Royal Gorge for most of the year, but it will get ELFy in a few weeks. Both are more like III or III+ at lower levels and become IV during run off. Pine Creek, above Numbers, which is an "V-" at normal flows, arguably drops down to a IV at lower levels as well.
Your best after work offseason run is probably Waterton (III), but you have to carry your boat back up ~ 1 mile or it would be a no-brainer. Google maps "South Platte Hotel" for the put in (run down from confluence to lake). Its still fun and worth the carry back up IMO, especially with a light playboat.
Some people surf Lyons for a few more weeks (St Vrain, BB hole).
Gore is mostly IV, IV+ with a couple V's and will be a step up with a few walk-arounds if you're not interested in V.
Baileyfest release may or may not happen. If it does happen, its a must go, IV+ creek with 2 walkable V's and a V+ portage.
Lower Blue (below Dillon, above Gore) has releases in the late summer and fall and is a III. I've heard its fun.
I'd boat with you but a baby is coming any day now, so probably done until next season.
Buy "Whitewater of the Southern Rockies" if you can find it.
