I had the pleasure of joining Jon, Chris and Mike for 4 days of pulling nets for the population studies on Lake Granby, through some crazy weather with anything from freezing rain, sleet and microbursts of hurricane force winds keeping things interesting.:biggrin1: We pulled 30 nets on Lake Granby, heres Jon with a nice Lake trout

http://imageshack.usWe noticed the sucker population has dropped this year and the lakers seemed to be putting a major dent in the populations. Heres Mike with a nice Laker that was sporting a half digested white sucker that we pulled out of him before sending him back.

Just in time to save the pelicans from starving and the Ospreys from heading south early, thanks to Rifle hatchery for coming up on 5-30 with 50,000 3"-4" Hofer rainbows and 2000 catchables.photo/my-images/818/img2057y.jpg/]

http://imageshack.us This week we had great weather, here's Jon with another nice Laker, another reason to release large lakers, we seemed to find a pattern of seeing a large laker in a school of little guys dining on and helping keep the overall population of Lakers down along with keeping the suckers population in check. We stole his fresh meal of a pink meated mysis eating laker out of him.

http://imageshack.us Heres a Glenwood hatchery truck with the start of 1.45 million kokanee getting stocked, we stocked 50k of them at Dike 3 that I last saw cruising down the shoreline and the rest are going in the river below Shadow mtn. The river was cranking at 1000cfs and it was pretty cool to see 500k kokanee fry going in.

http://imageshack.us It's been a great week and wanted to give a big thanks to Jon and his crew along with the hatcheries guys that help keep fish swimming in our waters.

Thanks for the info Steve,

Its sad the sucker population has crashed, or apparently crashed. Runoff is late, maybe they are late to migrate to their normal staging areas. The big lakers do have good populations of small lakers to feed on, but without suckers, (biting my tongue) I'm sure they will consume a fair number of stocker rainbows and kokanee.

Nice report on Granby, one of my favorite lakes looks to be still in good health.
With a lower population of suckers in the lake, will smaller lakers be next on the menu for the bigger lakers? If so, then will this be a good thing for the lake due to there being alot of little macks in there right now?
Also could a decline in smaller lakers help the koke population out by less of a battle for food between the two species?

Not to be difficult, but I think lakers feed on what is in front of them. Kokanee and small lake trout don't feed on the same food, small kokanee like plankton, small lake trout feed on mysis (in lakes that have mysis). Big Kokanee feed on plankton, big lake trout feed on everything that is in the water.

With the amount of Visitors and fishing pressure Lake Granby gets we deserve our fair share of rainbows, they feed the Ospreys, Pelicans, lake trout and the anglers, the more rainbows the better for the health of this fishery and angler opportunities. Lately we're getting the short end of the stick.

No, just one with an old tag wound but the tag was gone, in 3 years of netting they have not seen a single tagged fish. I recaptured 2 this past ice fishing season. Granby get's very few catchable rainbows per acre, comparably I bet it is among the lowest of any other reservoir in the state. 2000 catchable rainbows in a 7,200 acre lake this year so far, none until after memorial weekend. Instead of wasting tens of millions on a stupid clean water program, maybe it's time for a new hatchery.
