Fishing Synopsis and Forecast by Terry Gunn 4/19/08

The high flow experiment was basically a non event as far as the fishery is concerned. It came and went with few visible changes to the river or the fishery. For more details and to see my complete comments go here: http://coloradoriverconservancy.org/

Lots of stuff happening at the Ferry and it is all good!

Important Note: Due to the higher than normal runoff conditions and the desire to equalize Lake Powell and Lake Meade, water releases were increased on April 14. The projected increase amounts to more than 600,000 acre feet of water to be released between now and the end of the water year in October. This means that water flows will be higher than normal for the months of April, May, June, and July. Steady flows are planned for September and October. Read below how I predict this increased flows will affect fishing.

It has been a very different spring than most years. The air (and water) temperatures have been much cooler than normal and as a result, the midge hatches occurred much later than in past years. The swallows did not arrive until the first week of April, the exact same time as the midges started to hatch (how do they know?!). The swallows normally arrive Feb. 28 and this is the latest arrival that I have seen in my 25 years on the river. Most of the ducks are still here and they should have migrated several weeks ago which tells me that it is going to be a cool spring going forward and winter is going to be hanging on later than normal

The trout spawn began in early December which we have not seen in several years. It was a good strong spawn until the start of the experimental flow. Immediately following the high flow experiment the trout spawn began in earnest. It looked like every fish in the river was spawning at once and was the strongest spawn that I have ever witnessed. It was an inspiring sight, fish spawning everywhere and in areas that I have not seen them use in years. The spawn occurred in mostly deep water (up to 40-ft. deep!) with very little shallow water spawning taking place. The deep water spawn should translate into a “bumper crop” of fry and the survival rate will likely be off the charts.

This is going to be a year to remember at Lees Ferry…there are so many good things happening at once which will make this THE YEAR that will set the stage for great fishing for years to come. First and foremost: the current snowpack in the Colorado River drainage is 121% of normal, (Lake Powell is predicted to rise 50-ft!) and if the ducks are an indicator as to whether winter is lingering, the snowpack is likely to continue to increase. When the snow melt begins in earnest, the streams that flow into Lake Powell will be raging and stir-up all the accumulated sediment at the stream entrance. This sediment is nutrient laden and the suspended nutrients will be distributed throughout Lake Powell. All these nutrients will be transported and arrive in the river below the dam in a few months and the river will explode with algal growth and there will be lots of food for the fish.

Here is a quick overview and prediction.

The high runoff will provide the river with a huge nutrient load that will result in tremendous growth of aquatic organisms and plants (trout food).

The current trout population is healthy and the fish are larger than we have seen in years. These fish will grow rapidly to a larger size with the arrival of the nutrients and food. The current average 17-in fish should grow at least a couple inches and we have a bunch of fish that are bigger than that. We will see lots of 20+-in fish in the river next year.

The spawn from 2007 survival rate was substantial; the river is currently full of 7 to 8-in fish and the increased productivity of the nutrients should arrive just in time to stimulate growth of these juvenile fish. These fish will be 12-in and larger by this next fall and be catchable. The nutrient load should last at least a couple years even if next year’s snow pack is below normal. One strange phenomenon regarding juvenile fish at Lees Ferry is that once the fry reach 3-in long, they “disappear” until they reach 12-in and then suddenly they reappear and populate normal fishing lies. We’ll be seeing these fish this next fall.

I have already told you about the trout spawn from this year. The number of trout fry will likely be off the chart and the survival should be good. The river conditions should be perfect for survival and growth of these young of the year fish and they will show up as 12-in or larger fish in the fall of 2009.

Higher water flows always provide better health and growth rates for trout at Lees Ferry. Due to the projected run-off and the desire to equalize Lake Powell and Lake Mead, the planned release volume from April to October is being increased from 8.23 million acre feet of water to 8.88 million acre feet which is an increase of more than 600,000 acre feet of water. To help put this into perspective this increase is more than all the water that will be released in the month of April. This is the first time since 1997 that there has been a release larger than the minimum of 8.23 million acre feet. For those of you that remember what the fishing was like in 1999 and 2000…you should be as excited as I am about what this higher water and increased nutrient load should do to the fishing at Lees Ferry.

In the short term the higher water will make fishing conditions tougher. The trout normally stop feeding on sub-surface midges when the water flows exceed 12,000-cfs and the flows will exceed this value for the remainder of this season. The fish will shift their diet to worms and scuds in the higher flows which means we will be using heavy nymph rigs and be doing more drifting than wading.

For a real time graphic view of water releases and ramp rates go here: http://waterdata.usgs.gov/az/nwis/uv?09380000

Overall the trout are in great shape and the average size is larger than we have seen in several years. I predict that the size and condition of the fish will continue to improve this spring and summer and we should continue to see great fishing for the remainder of 2008 and into the future

New guides at Lees Ferry Anglers. The last couple of years we have had several long time guide staff move on to bigger and hopefully better things. This year I’m proud to introduce 4 new guides, though new to our organization they are not new to guiding. Luke Blaser, Nick Gibb, Tom Jones, and JD Miller have joined our team. They bring with them a couple of decades of combined guiding experience on various waters around the world, college degrees, and an enthusiasm for guiding that is contagious. I’m proud to introduce these fellows and I’m sure that you will agree that they are a great addition to our team.  

The AZ Game and Fish Department recently detected whirling disease in a small percentage of Lees Ferry trout that were collected for a random sampling. A recent sampling turned up no sign of the disease, which may mean that it was a “one time” exposure, where the disease was not established or that the disease is present but at a very low prevalence.  Anglers should still use caution in cleaning their equipment both before and after they have fished here or in other waters. For more information visit: http://www.whirling-disease.org 

I have had some people that are fishing on their own (unguided) tell me that they are having a difficult time catching fish. The fishing has changed from the peak of 2000 and many people are not adapting to the new conditions. The current fish population is lower than it was in 2000 and there are not fish “everywhere” in the river like there were several years back (this is probably the reason that we are seeing better conditioned and larger fish today). Just because you might have been successful in one spot on the river in the past does not mean that particular spot is always good. There are many times of the year that the water flows, or conditions are not right to hold fish at “famous” spots such as 4 mile or Dam Island. It is often challenging, even for a good guide, to stay on top of where the fish are and what they are eating; but we do have the advantage of spending a lot of time on the water.
