Restorative Lake Sciences (RLS) was out on Thursday, June 29th for the 2023 lake scan & evaluation. They also took water samples from the lake (2 spots) and from the river before the pump.
They found no evidence of Eurasian Watermilfoil, this is the invasive plant that we have had for many years. The absence of the Watermilfoil can be attributed to the systemic treatment that we did last June with Triclopyr.
The predominant plant this year is Curly-leaf Pondweed (CLP). While the CLP is not a native plant, it is not undesirable like the Eurasian Watermilfoil. The recommendation from RLS is to not treat the CLP since it will die off in late July to early August.
The cloudiness of the water is due to algae growth.
We did have dense areas of filamentous algae in Wacko Bay in early June and in the river by the pump inlet in late June. We spot-treated Wacko Bay on June 7th and the river on June 28th. Filamentous algae, while not desirable is not toxic.
The treatment recommendation for Tull Lake #2 from RLS is for the algae only. They recommend we treat that with Chelated Copper along the shoreline of the lake.
