Large Scale Lake Planning
The objectives of these investigations were to examine the development of summer algal blooms in Big Round Lake (Table 1) in relation to P loading from the Straight River watershed and from bottom sediment during temporary anoxia. The goals of this research were to develop an estimate of summer watershed and sediment-derived internal P loading for use in P budgetary analysis and future forecasting of the impacts of internal P loading management on water quality.
Although a comprehensive lake plan is in effect from 2016 through 2025, this aquatic plant management plan (APMP) was initiated to focus on curly-leaf pondweed, phosphorus loading, and algae blooms. The Big Round Lake Protection & Rehabilitation District (District) was formed in 1967 and is the entity sponsoring this APMP. The District partnered with Aquatic Plant and Habitat Services LLC to create a 5-year management plan that is WDNR-approved and District-adopted. Public input was gathered in April 2019 (Section 10.0) and the management plan was released for public and WDNR review in June 2019.
