We held the first Mack Days in the fall of 2002 to help correct an imbalance in the Flathead Lake trout fishery caused by the continually increasing population of lake trout. Mack Days represents a new approach to fisheries management, one that that strives to directly involve the angling public in shaping the fish community. The success of the events continues to grow, and we commend the angler's for their part in this success. So far, the levels of lake trout being harvested are not sufficient to significantly reduce the lake trout population in the lake. So it is important to continue to build these events and maintain them in the future. Thank you for your help and participation in Mack Days and have fun exploring our website to learn more about the contest and the lake.

PLEASE IDENTIFY YOUR CATCH CAREFULLY!
It is very important to correctly identify each fish you catch-especially the smaller fish. It can be difficult to tell small bull trout from small lake trout. If you are in doubt about the identity of the fish, put it back. We had an unacceptable level of bull trout catch and harvest during the 2011 contests. This undermined our objective to benefit native fish and threatens the future of the contests.
- Bull trout have no black spots on the dorsal fin, and orange spotting on the sides of the fish can be very light and difficult to see.
- Examine the top of the back. Spots on a bull trout will be distinctly rounded and uniform.
- Flatten the tail out wide. Bull trout will have a tail that is squarer than lake trout. Although some smaller bull trout will have a slight V shape and be confused with lake trout.
- Please carefully study the fish ID page on this website.
Starting this year we are required to report all bull trout entries to the authorities. Let’s strive for zero mistaken identities this year!
Watch the Trout Unlimited Bull Trout Public Service Announcement:
ALERT: STAY CLEAR OF SCIENTIFIC BUOYS!
Please stay at least 300 feet from the Biological Station's two new instrumented buoys in Flathead Lake to prevent entanglement of your fishing lines with the cable that goes from the surface of the buoy to the lake bottom and to avoid damaging this expensive equipment. For more information click here.
Webcams show boats frequent the area around the midlake buoy, which is troublesome because they could easily destroy the instrument accidentally by entangling a fishing line on the electrical cable that goes from the buoy to the lake bottom. The second buoy is west of Woods Bay, which is a very popular fishing site. So please take care to stay at least 300 feet away from these very important and very expensive instrumented buoys.
Attention Mack Days Anglers
The 2013 Fall Mack Days marks the first fishing contest following the completion of the Draft Environmental Impact Statement: Strategies to Benefit Native Species by Reducing the Abundance of Lake Trout, and the decision by the Tribal Council to proceed with lake trout suppression using the full range of tools available to us. Although additional decisions are pending in this lengthy process, it is likely that an expanded reduction program will proceed in 2014. Therefore it is especially important to establish an accurate baseline of the lake trout population to reference future changes in the population. We have several methods to generate the baseline, with the mark and recapture method to estimate population abundance being one of the most useful. The accuracy of the estimate is greatly influenced by the number of fish we can mark and release. To achieve the largest sample, we will be relying on the anglers to help us mark as many fish as possible. Every Friday we will have one or two crews on the lake circulating among the anglers to collect fish for marking. If you have a livewell, please hold your fish in clean and cold water until one of the boats can pick it up. We will identify areas where the boats will work on each Friday so you can better coordinate with them. Starting this year we will add a new mark, a hole punch in the anal fin, in addition to removal of the adipose fin, to identify marked fish. If you have fish that can be tagged your name and number of fish will be turned in for tickets. The fish will be counted on your total for the day.
