Lida Lake is located in Otter Tail County, 4 miles east of Pelican Rapids, Minnesota. Lida Lake has two basins, the main basin with a surface area of 5,564 acres and the south basin with a surface area of 856 acres. With a total surface area of about 6,420 acres, it is ~among the top five percent of lakes in the state in terms of size. The main basin of Lida Lake has a maximum depth of 58 feet and a mean depth of 19 feet. The southern basin has a maximum depth of 48 feet and a mean depth of 21 feet. The total watershed is approximately 43 square miles (27,299 acres). Land use in the watershed is characterized primarily by forested (35 percent) and wetland (27 percent) uses. These values are very comparable to other lake watersheds in this region of the state - North Central Hardwood Forests ecoregion. Lida Lake was sampled during the summer of 2000 by the Minnesota Pollution Control Agency (MPCA) staff. Main basin water quality data collected during the study reveal summer-mean total phosphorus (TP) concentration of 16 ?g/L, chlorophyll-a of 6.2 ?g/L and Secchi transparency of 10.3 feet. South basin water quality data collected during the study reveal summer-mean total phosphorus (TP) concentration of 24 ?g/L, chlorophylla of 11.5 ?g/L and Secchi transparency of 8.2 feet. All three parameters from both basins are well within or better than the range of values exhibited by reference lakes in the NCHF ecoregion. Total phosphorus, chlorophyll-a and Secchi transparency help to characterize the trophic status of a lake. These measures indicate mesotrophic conditions for both basins of Lida Lake.
