Peatland is located in the northern part of Ida-Viru county, in a flat depression. The southwestern part passed through byTallinn-St. St. Petersburg highway. The peat formed by terrestrialisation of the lake (there is a 0.4 m thick layer of lake mud under the peat) (Orru, 1975). It feeds on moraine water and precipitation, the water recipient is the Ontika main ditch. Peat lies on moraine. In the peatland spreads wooded mire and wooded bog , 168 ha are cultivated. The area of the peatland is 1162 ha, of which 277.47 ha is peat deposit; registry card no. 539; 0.056 million tons are slightly decomposed peat economic probable reserves and 0.756 million tons well-decomposed economic probable reserves . There is 1054 ha of fen deposit and 108 ha of bog deposit. The fen deposit consists of well-decomposed wood- reed peat (42%), with an ash content of 7.6% and a moisture content of 90%, thickness 1.03 ... 2.0 m. The bog deposit is formed by slightly decomposed (12%) Sphagnum peat (0.75 m) at the top, well-decomposed (38%) pine peat below it, and transitional peat at the bottom of the profile (Orru et al., 1975). The deposit is drained. Geological surveys are required for the commissioning of the peat deposit. The list of usable peatlands compiled by the Ministry of the Environment includes 200 ha of promising stocks (Regulation no. 87; 27.12.2016).
