The fall 2017 turion survey predicted there would be little CLP outside the northwest bay; and, following a long winter with nearly record late ice-out, the May 12, 2018 pretreatment survey found so little CLP that it was decided to cancel the 2018 treatment (Figure 3). Hoping CLPs recovery without treatment would be minimal, the LLPRD, requested a late fall survey to determine the level of any latent CLP turions in the lakes substrate.

Prior to the planned 2018 herbicide application, we conducted a pretreatment survey of the lake on May 12th to determine initial CLP levels and finalize treatment areas. Because this survey found little CLP, it was decided to cancel the 2018 treatment. However, in order to see how CLP and native plant populations responded to skipping treatment, it was requested that we do a follow-up survey on June 11th. This report is the summary analysis of these two surveys.
