LAKE STURGEON SPAWNING

SPAWNING SEASON 2023

May 3, 2023 – Warmer water temperatures over the next few days will likely trigger spawning throughout the Winnebago System. On the Lower Fox River, no sturgeon have been reported below the De Pere Dam yet, but DNR staff expect sturgeon will begin showing up soon. On the Peshtigo River, an estimated 75-100 sturgeon have been seen below the Peshtigo Dam, though they are not yet actively spawning. On the Wolf River, more lake sturgeon are showing up at New London again. While these fish are not actively spawning, they can be seen on the Sturgeon Trail and will likely start to spawn soon. Currently, no fish were seen at Bamboo Bend in Shiocton or at the dam in Shawano, but more fish might be seen there later in the week as water temperatures increase.

Because of the late nature of this spawn, it is likely that any spawning on the Winnebago System will not last long. Please check back regularly for additional updates.

April 28, 2023 – No sturgeon have been reported below the De Pere Dam, but there is some pre-spawning activity occurring at the Shawano and Peshtigo dams. DNR staff believe the historical trend of sturgeon spawning on the Peshtigo River the first week in May will hold true again this year. However, we likely won’t see sturgeon start spawning this weekend on the Wolf, Peshtigo or Lower Fox rivers due to the projected cold weather. We will post another update once spawning activity starts, so check back for updates.

Earlier Spawning Reports

April 27, 2023 – No sturgeon have been reported below the De Pere Dam yet. A few sturgeon are still cruising at the Shawano Dam, and roughly 20 sturgeon have been seen staging below the Peshtigo Dam.

April 26, 2023 – A few sturgeon have been spotted cruising again at the Shawano Dam, and about 20 sturgeon can be seen at the Peshtigo Dam from the viewing platform. There are also a few sturgeon below the Stiles Dam on the Oconto River. While there are still no sturgeon visible below the De Pere Dam, water temperatures have started to rise, and the warmer weather over the next couple of days may get some sturgeon to move up to the dam. Check back in for updates!

April 25, 2023 – Sturgeon are still in a holding pattern on the Wolf River, but DNR staff are hopeful spawning will begin again soon. Sturgeon on the Lower Fox River aren’t quite ready to start spawning with the lower water temperatures. However, about a dozen sturgeon were spotted staging below the Peshtigo Dam today and can be seen from the viewing platform. Bring polarized sunglasses for the best viewing. A few sturgeon were also seen below the Stiles Dam on the Oconto River.

April 24, 2023 – Spawning activity has not resumed on the Wolf River, nor has it started on the Oconto, Peshtigo or Lower Fox rivers. Check back for updates.

April 23, 2023 – Spawning has halted again on the Wolf River due to the weather. A few sturgeon were seen porpoising below the Stiles Dam on the Oconto River today, but no sturgeon have been seen below the Peshtigo Dam on the Peshtigo River. Some sturgeon have been spotted downstream of the De Pere Dam, indicating spawning may start soon on the Lower Fox River. We’ll update this webpage with any information, so check back frequently.

April 22, 2023 – The erratic weather this spring has made spawning activity inconsistent on the Wolf River. While some sturgeon can still be seen at the Shawano Dam, the high water and excess foam make it difficult to see them, and sidewalks are still barricaded off due to the high water levels. Although no spawning activity has started on the Peshtigo River, a lone sturgeon was seen at the De Pere Dam, indicating that we are getting closer to seeing sturgeon spawning on the Lower Fox River. Check back for updates.

April 21, 2023 – Spawning activity has not started yet on the Peshtigo or Lower Fox rivers. Sturgeon are spawning at the Shawano Dam, though they may be difficult to see with the high water. Check back frequently for updates.

April 20, 2023 – Spawning activity is occurring at the Shawano Dam; however, the walkway is inaccessible due to high water levels. No sturgeon have been reported spawning at the De Pere Dam or on the Peshtigo River. Check back frequently for updates.

April 19, 2023 – Colder temperatures are still impacting the sturgeon spawn on the Wolf, Lower Fox and Peshtigo rivers. No sturgeon have been seen spawning at any of these locations, but that could change later this week. Check back frequently for updates.

April 18, 2023 – Cold water temperatures have continued to pause spawning on the Wolf River. No sturgeon have been seen at the De Pere Dam or on the Peshtigo River yet. Spawning may resume later in the week at some locations, so check back frequently for updates.

April 17, 2023 – Water temperatures have dropped due to the cold weather, pausing spawning on the Wolf River. No sturgeon have been seen at the De Pere Dam or on the Peshtigo River yet. Spawning may resume later in the week at some locations, so check back frequently for updates.

April 16, 2023 – Due to the cold weather, spawning has cooled. Sturgeon can still be seen on the Wolf River at Bamboo Bend and New London but not at the Shawano Dam or on the Peshtigo River. A few sturgeon have been spotted jumping in the Lower Fox River a couple of hundred yards below the De Pere Dam at Voyageur Park. It may be difficult to spot them in shallow water, though. Check back frequently for updates.

April 15, 2023 – Sturgeon are still actively spawning on the Wolf River at Bamboo Bend, New London and Princeton but hasn’t started spawning at the Shawano Dam or on the Peshtigo River. A few sturgeon have been spotted splashing a couple of hundred yards below the De Pere Dam on the Lower Fox River. The severe temperature drop and rain may affect these sturgeon, so check back frequently for updates.

April 14, 2023 – While no activity has been reported at the De Pere or Shawano dams yet, fish are cruising on the Wolf and Upper Fox rivers. Sturgeon have been seen actively spawning at Bamboo Bend, New London and Princeton. Sturgeon has not begun spawning on the Peshtigo River yet. Check back frequently for updates.

April 12, 2023 – Lake sturgeon have not started spawning on the Wolf, Peshtigo or Lower Fox rivers. Please check back frequently for updates.

April 11, 2023 – The 2023 lake sturgeon spawning season is approaching. Winnebago System fish are getting ready to make their run up the Wolf River to the Shawano Dam. Sturgeon have been seen at Boom Cut waiting to make their way up the Wolf River.

Lake sturgeon spawn at about 53 degrees Fahrenheit. If high water levels are a factor this spring, spawning will likely be delayed. As of today, the water temperature is 51.4 degrees Fahrenheit.

 

STURGEON SPAWNING

From mid-April to early May, Lake Sturgeon travel upstream to their spawning grounds, giving the public a prime opportunity to see these ancient ones up close.

Sturgeon spawning is dependent on water temperature and flow. During seasons when water flow is high and water temperatures rise slowly, spawning begins when the water temperature reaches 53 degrees Fahrenheit. In contrast, during seasons of low water flow and more rapid water temperature rise, spawning does not begin until water temperatures reach 58-59 degrees Fahrenheit.
