Up-River Summary

It is winter time in the canyon which means that the days are short and the sun is hard to find but the fish don’t really seem to mind. December and January are high volume water flow months which means that the high water is moving food around and the fish are feeding. There have been some great reports from guides who are drifting and fishing from the boat. The key is to have a long leader and a heavy weight that will get your flies down to the bottom where the fish are feeding. The wade fishing can be really good also, but there are fewer spots to wade in the high water. Current conditions will remain the same through January and the fishing should stay good and consistent. Remember that the water flows are slightly lower on the weekends due to lower power demand.

Current snow pack in the Rockies is looking good. It was a slow start this fall but snowpack in near normal with some big snows projected from some impending storms. Lake Powell needs a big snow pack year.

Just because you caught fish in a certain spot in years past, don’t think that you are going to experience the same success again. The river is a living creature and fishing changes daily. It is our sincere desire that everyone have a great trip to the Ferry. Be sure to stop by the shop to see the flies that are currently working. The flies frequently change on a daily basis – sometimes it seems like hourly – and LFA guides let everyone at the shop know the top producing flies and how to use them. We are anxious to share this knowledge with you – even where to fish!

There is an ongoing aquatic food base study that has taken place over the past couple of years. The purpose of this study is multifaceted and is studying the relationship of flows on food production, taking inventories of and monitoring populations of aquatic insects and invertebrates that live in the river and other very important aspects of the aquatic food base. I believe that this is by far the most important study that has ever been conducted on this river. Previously, hundreds of millions of dollars were spent studying sediment while ignoring the aquatic food base and resource. Common sense dictates that fish, birds and animals do not live off dirt or sand. The aquatic food base and habitat are the foundation for all that lives in the Colorado River. One of the long-term goals of the food base study is to determine how to enhance the populations and production of aquatic insects in the river which will benefit native fish, trout, and migratory bird populations. This is a study and a goal that we can all embrace!

Quagga mussels (see http://nas.er.usgs.gov/queries/factsheet.aspx?speciesid=95 ) have become established in Lake Powell and we are now seeing some in the river below the dam. Their arrival happened sooner than I expected. So far, there has not been a major infestation and there is some thought by experts that they will not become very well established in the river due to the current. Remember to dry waders and boots before using them in any other body of water. Also, private boats should drain all water from the boat and live-wells as soon as you exit the river. We all need to do our part to limit the transport of this and all invasive species.

Walk-In Summary

We have been hearing some good reports from the Walk in area. It appears that the higher water has prompted the fish to move in closer to the shore. The fish have been holding deep in this area for the last couple of years and it appears that this might be changing.

Spin Fishing Summary.

Spin fishing continues to be productive. Many of the fish are in the deeper water and it is much easier to get down to them with spinning gear than fly gear.

Dam Operations

November 30, 2016

The release volume from Glen Canyon Dam for December 2016 will be 900,000 acre-feet.  Hourly and daily average releases from Glen Canyon Dam for December 2016 will be scheduled through Western Area Power Administration to be consistent with the Glen Canyon Dam Operating Criteria (Federal Register, Volume 62, No. 41, March 3, 1997) and to also achieve, as nearly as is practicable, this monthly volume.  Hourly releases during December 2016 are anticipated to fluctuate between approximately 19,000 cfs in the daytime and approximately 11,000 cfs in the nighttime.

We anticipate the release volume for January 2017 will be approximately 900,000 acre-feet with fluctuations between approximately 11,000 cfs and 19,000 cfs.  The anticipated release volume for February 2017 is 700,000 kaf.  This will be confirmed in a subsequent notification toward the end of December.

This notification supersedes all previously issued notifications and is current until a new notification is issued.  All times identified in this notification are local time (Mountain Standard Time) and not hour ending.
