2. MN: Starry stonewort nearly introduced into Lake Superior.
Luckily a watercraft inspector was paying close attention:
> A DNR watercraft inspector saw what appeared to be grass in the motor intake of a boat whose owner approached the Agate Bay public water access to Lake Superior in Lake County. Upon closer examination, the inspector noticed the small star-shaped bulbils that indicate starry stonewort. The boat owner said the boat had been on Bowen Lake in Cass County the previous weekend. Starry stonewort was confirmed on Bowen Lake in Aug. The inspector used the decontamination station on site to ensure the invasive species was removed before the boat entered Lake Superior.
Props. 👊
3. MN: Possible walleye reg changes upstream of Island Lake Rez.
> Parts of the Otter and Cloquet rivers accessible upstream from Island Lake would have the same regulations as the lake.
> The proposed regulation for the Otter River from the mouth to the Boulder Lake dam, and the Cloquet River from the mouth to the rapids a half-mile upstream, would require anglers to release all walleye 15-20″ in length, with 1 fish allowed > 20″, the same regulation in place on Island Lake Reservoir. …also would increase those sections of river to the 10-walleye daily possession limit….
4. ID: Walleye #s rising at Lower Granite Dam.
Which at first sounds like good news…but they’re worried about walleyes preying on young salmon and steelhead:
> Walleye have spread throughout the Columbia River basin following an unauthorized introduction to Lake Roosevelt in the mid-20th century. These fish have remained downstream of ID’s salmon and steelhead rivers until recently. Data collected at the Lower Granite Dam adult fish trap has shown that walleye have been moving through the fish ladder and likely passing over this dam since at least 2016 (2016=2; 2017=11; 2018=49; 2019=20; 2020=45; 2021=75).
> Walleye are effective and opportunistic predators that will prey on emigrating salmon and steelhead smolts. Juvenile salmonids in ID rivers and streams are already affected through predation by native and non-native birds and fishes, and as more walleye continue to move and colonize upstream of Lower Granite, predation rates will continue to rise. Researchers downriver have estimated that the average walleye eats around 2.5 smolts per day in the spring (McMichael and James 2017), and that non-native predators, including walleye, might be eating up to 17% of certain populations of juvenile emigrants (Harnish et al. 2014). This scale of mortality can reduce adult returns.
5. MN: Lake Minnewaska stocked w/2,500-lbs of walleye fingerlings…
…last week by the Minnewaska Lake Association (MLA).
6. NE: Boating access limited on some reservoirs.
Due to drought – water levels haven’t been this low since 2012. Game and Parks has been doing some repairs where they’re able to.
