the sudden depth area in the middle is great if you just actually want to swim instead of first having to wade for ages before it gets deeper, just follow the warning signs

Diverse vegetation is also resilient and adapts to changes in land-use and variation in weather conditions. The extent of the services that wetlands provide to people depend on wetland design and well-being, as well as on land-use within the contributing watershed and weather dependent pollutant loads. Constructed wetlands typically consist of a flow dissipating and heavy sediment settling inlet pond, a vast shallow emergent plant covered wetland, and a sediment settling outlet pond. The Säynäslanhdenpuro Wetland consists of three parallel research wetlands with flow and pollutant load monitoring facilitating outlet dams.

A stormwater wetland is a constructed transitional landscape between water and dry land. Wetlands are natural water detention and purification landscapes. Constructed wetlands are thus established to compensate for challenges to water environment brought about by land-use change. Urban wetlands dissipate and detain runoff thereby preventing flooding and drought extremes. Water quality is mitigated through sediment settling, and purification of soluble pollutants by wetland plants, microbes and soils. Diversity of plants and their associated microbes is a key element in purifying urban waters.

Land-use change in urban areas from natural to impervious surfaces such as roofs, paved yards and asphalt roads prevents water infiltration and storage within the watershed. Runoff travels quickly over impervious surfaces collecting and carrying everything from surfaces to catch basins and sewers. Impacts visible at the storm sewer outlets to urban streams include flooding, drought and erosion. Depending on land-use within the watershed, runoff carries harmful substances such as nutrients, heavy met- als, oils and rubbish. The receiving water body suffers from habitat degradation while the impervious and drained watershed often experiences draught and heat.

Hietaranta beach is the most popular beach in Helsinki, especially in warm weather. The full length of the beach is monitored, and the swimming area is marked with red and yellow flags and buoys. Sudden drops in the swimming area are indicated by yellow warning signs. The main building located in the middle of the beach has toilets, changing rooms, a restaurant and a watch tower. There are also several beach volleyball courts, an outdoor gym and outdoor exercise equipment for independent training. The beach is monitored throughout the swimming season.

I managed on the path with tyres ment for asphalt. Partly path has big stones and roots of the trees on the way but mostly route is enjoyable with bicycle. By The Lake of Bisa there are wooden bences built right near the water, where you can eat your picnic or just enjoy the view. Also next to the lake is a rocky hill. On the top of the hill is cooking shelter, where you clime up along built stairs. The view is beautifull, over the lake area.
