The fisheries conservation area extends between the municipalities of Södertälje, Salem and Botkyrka, most of the association's water is in the municipality of Salem. The surroundings are typical of the Sprickdal landscape on Södertörn. Dånviken and Flaten are relatively small and shallow while Uttran is larger and is at its deepest 16 meters.
In Uttran there are perch, birch, bream, pike, pikeperch and yeast. The perch stock in particular is both in good condition and has large individuals.
In Flaten and Dånviken there are pike and perch. There is an implanted population of pikeperch in Uttran.
The lakes are relatively eutrophicated and are not expected to reach the set targets for environmental status in time, especially not with regard to eutrophication substances, mercury and certain brominated flame retardants. Nevertheless, measured values are below the limits of what is considered to be suitable food in fish from the lakes.
All the lakes' water flows via the Tumbaån river out into Lake Albysjön to Lake Mälaren and then out into the Baltic Sea.
