Fishery survey reveals winter kill impacts at Crescent Refuge and Blue Lake management plans

The Nebraska Northwest District Fisheries Meeting, held on May 23, 2025, focused on various updates regarding local fisheries and management strategies. The meeting began with a discussion about the Onyx Fish app, which utilizes fisheries data to assist anglers. However, attendees expressed limited familiarity with the app, indicating a need for further exploration of its features and benefits.

Following this, the meeting shifted to an update on the Crescent Refuge. It was reported that the refuge experienced a significant winter kill, the worst documented among surveyed lakes, with no fish found post-event. Despite this setback, there have been no sightings of carp since the renovation, and restocking efforts are underway. Fisheries staff plan to set nets in Island Lake and South Smith to assess the recovery of these ecosystems.

The discussion then moved to Crane Lake, where low water levels have hindered thorough evaluations. Although no winter kill occurred there, staff have not had the opportunity to conduct recent assessments. In contrast, Crescent Lake, while not part of the refuge, has shown promising results with a strong walleye catch and a healthy population of perch. Management efforts include stocking gizzard shad to control common carp and improve the condition of predator fish.

Attention was also given to Sand Hill Lakes, particularly Blue Lake, where panfish populations are struggling. Plans to introduce gizzard shad into Blue Lake aim to manage carp populations effectively. Despite the challenges, Blue Lake remains a notable location for walleye and crappie fishing, with good numbers of crappies in the 10 to 12-inch range.

In summary, the meeting highlighted both challenges and successes in local fisheries management, with ongoing efforts to monitor and improve fish populations across various lakes in the district. Future assessments and management strategies will be crucial in addressing the issues raised during the meeting.
