2025 FORT PECK
Final Update – April 20th
Weather conditions have remained favorable for the most part in the Big Dry Arm of Fort Peck Reservoir. Water surface temperatures have ranged from 45 to 51F over the course of the last several days. These water temperatures have allowed us to capture good numbers of ripe female walleye throughout most of our trap netting locations.
Thanks to consistent numbers of ripe female walleye captured in the trap nets, we’ve managed to hold an egg-take each day since the last update (see below). As you can see below, the number of walleye eggs collected from April 19th to April 20th doubled. This was due to an increase in water temperatures – 46 degrees on Saturday warming to 51 degrees on Sunday. It should also be noted that this timeframe is when we typically see the peak of the walleye spawning activity occur in the Big Dry Arm area.
April 17th – 6.1 million
April 18th – 6.7 million
April 19th – 5.9 million
April 20th – 13.1 million
These four egg collection efforts gave us an additional 31.8 million eggs which quickly brought the total to approximately 62 million eggs for the season. This will provide enough eggs at the Fort Peck and Miles City fish hatcheries to meet fry and fingerling stocking requirements for 2025. In addition to the walleye eggs, a total of 1.5 million northern pike eggs were collected to meet stocking requests for several waterbodies here in Montana.
On behalf of the fisheries and hatchery staff at Fort Peck, I’d like to thank all the volunteers who assisted with this year’s efforts. Be safe on the water and best of luck fishing this year!

April 16th
In general, the weather has been pretty cooperative in the Big Dry Arm area of Fort Peck Reservoir. Water surface temperatures have been hovering around 49-51 degrees in some of the shallow areas while checking our trap nets today. Fortunately, the cold front that moved through the area since the last update wasn’t as severe as anticipated.
Numbers of walleye captured per net have remained steady for the most part with the favorable water temperatures. We’re continuing to see good numbers of male walleye but were beginning to capture more ripe (releasing eggs) female walleye in the trap nets. Thanks to the increased numbers of ripe female walleye collected from the trap nets, we’ve been able to hold an egg-take almost every day since the last update.
We were able to collect walleye eggs every day except Sunday when it was extremely WINDY. Each egg-take day averaged 5 million eggs giving us close to 20 million eggs in a relatively short time. These multiple egg collection efforts have quickly brought the total close to 30 million eggs. Based on the numbers of ripe female we’ve been capturing and the consistent egg-takes, there’s a good chance we could be wrapping things up in the near future.

April 11th
The weather has been very cooperative for us in the Big Dry Arm area of Fort Peck Reservoir. Water surface temperatures have been hovering around 49-51 degrees in some of the shallow areas while checking our trap nets today. This has been encouraging for walleye spawning activity.
Numbers of walleye captured per net have increased with the warming water temperatures. We’re continuing to see LOTS of male walleye (and some big ones up to 26 inches) along with some green (not ready to spawn) and ripe (releasing eggs) female walleye. Thanks to the increased numbers of ripe female walleye collected from the trap nets, we’ve been able to hold two, small egg-takes since the last update.
On Wednesday (April 9th) we collected 3 million walleye eggs and today (Friday) we collected 6 million more eggs. These two egg-takes brought our total to approximately 9 million eggs which means we’re on the board for 2025 season. However, it looks like a cold front is headed our way starting Saturday afternoon with winds forecasted to gust up to 40 mph on Sunday.

April 7th
The walleye trap netting and egg collection is underway on Fort Peck Reservoir. Actually, it’s been more of a trap netting effort than an egg collection so far with the colder water temps early on. Water surface temperatures on Saturday (April 5th), which was our first day checking nets, were 38-40 degrees throughout our trap netting locations. Today (April 7th) water surface temperatures gradually increased to 45-47 degrees and a few more walleye decide to show up in the trap nets.
As with the beginning of every walleye spawn, male walleye are typically more abundant. That pattern is holding true with a majority of the walleye being males, and only a few green females (not releasing eggs) have been captured thus far. We have yet to collect any walleye eggs since it’s early and water temperatures are still relatively cool. It’s possible walleye spawning activity could increase over the next few days as temperatures are forecasted to remain warm.
