The Wyoming Game and Fish Department has issued a call to arms for trout enthusiasts, urging them to take a break from fishing in the Upper North Platte and Encampment rivers during the sweltering summer months. This voluntary pause is a crucial step in safeguarding these prized trout fisheries, which are facing unprecedented challenges due to rising temperatures and low water flow.
The department's release highlights a dire situation: unseasonably warm temperatures and low-flow conditions are causing stream temperatures to soar, regularly exceeding 70 degrees Fahrenheit in the afternoon and evening. This extreme heat has a devastating impact on the trout population, as warm water holds less dissolved oxygen, making it harder for fish to recover from the stress of being caught. As temperatures approach 70 degrees, the chances of released fish surviving plummet.
The situation is even more critical when temperatures reach 75 degrees or higher, as prolonged exposure can be lethal for trout. Brief exposure to temperatures above 80 degrees often results in death. These findings emphasize the urgent need for anglers to adjust their fishing practices to protect these fragile ecosystems.
The department's request for a voluntary fishing pause is a strategic move to prevent further stress on the trout population. The Upper North Platte River, in particular, is a major concern due to its sustained high temperatures, even during early morning hours. Signs will be posted at major public access points to inform anglers of the voluntary closure, which will be monitored and potentially extended to catch-and-release angling if temperatures moderate.
Caroline Rosinski, Laramie Region fisheries biologist, emphasizes the importance of this initiative, stating, 'The Upper North Platte River is our greatest concern in the region at this time. The last week of warm weather has resulted in sustained high temperatures, even in the early morning hours. The best thing we can do at this point is prevent any additional stress by encouraging anglers not to fish.'
The Encampment River is also under scrutiny, but it is still cooling off overnight and into the morning hours. Anglers are advised to voluntarily fish only in the morning to avoid adding stress to trout during the warmest times of the day. Rosinski adds, 'We all love these fisheries and want to see them thrive into the future. The conditions trout are experiencing right now are tough, and anglers can have a meaningful impact by abiding by these voluntary closures.'
The department's monitoring of temperatures will determine the duration and modification of these voluntary closures. Anglers are encouraged to check the Wyoming Game and Fish website for updates on closures across the state. Additionally, the department provides valuable tips for anglers to help improve the survival of released trout, such as carrying a pocket thermometer and adjusting fishing practices as water temperatures rise.
In conclusion, the Wyoming Game and Fish Department's voluntary fishing pause is a critical measure to protect trout fisheries from the devastating effects of rising temperatures. Anglers are urged to heed this call and contribute to the conservation of these precious ecosystems. By working together, we can ensure the long-term health and sustainability of these blue-ribbon trout fisheries for future generations to enjoy.
