Baker Lake is a mesotrophic lake (TP ~ 26 µg/L). The lake has a public access and an undeveloped shoreline. The lake surface area is 19.3 hectares, mean depth is 4.8 m and the maximal depth is 9.5 meters. The lake is dimictic and during summer stratification a relatively large proportion of the lake below the thermocline is depleted in oxygen. The lake has a high vertical light attenuation coefficient of 0.61 which is the result of humic content and high productivity with Chl-a averaging 10.6 µg/L. Common planktonic cladocerans in summer are Daphnia dentifera and Daphnia pulicaria and Diaphanosoma birgei. The main planktivores are bluegill (Lepomis macrochirus) and pumpkinseed (L. gibbosus) sunfish, large mouth bass (Micropterus salmoides) is the main piscivore.
