Project deliverables include: 1) Stakeholder survey, news release(s), and newsletter article; 2) Water chemistry data; 3) Watershed maps and modeling data; 4) PI, shoreland and woody habitat data; 5) Aquatic plant community, acoustic and substrate maps; 6) Aquatic plant vouchers; 7) LMP. Specific conditions for this project: 1) Draft of stakeholder survey needs Dept review and approval; 2) Draft of LMP needs Dept review and approval.

At the time of this report, the most current orthophoto (aerial photograph) was from the National Agriculture Imagery Program (NAIP), collected in the summer of 2015. Based on heads-up digitizing the water level from that aerial photograph, this lowland drainage lake was determined to be 553 acres. According to a 2017 acoustic survey of the lake, Lost Lake has a maximum depth of 24 feet and a mean depth of 11 feet. This eutrophic lake has a relatively large watershed when compared to the size of the lake. Lost Lake contains 34 native plant species, of which slender naiad (Najas flexilis) is the most common plant. Two exotic plant species are known to exist in Lake Lost, Eurasian watermilfoil and curly-leaf pondweed.
