- How is the water quality in your water areas?
Tollense river is blessed with factors that nurture the water quality like forest areas, agricultural lands, artificial weirs that controls water balance, suitable temperature, and biodiversity which contributes qualities.
•Role of agricultural lands and forests
From the literature study examining various land maps, it is evident that many parts of the Tollense river have numerous forest and agricultural lands along the river. The presence of this dense vegetation nearby increases the oxygen content in the river body. Freshwater sediments release phosphorus in a dissolved form that can be readily taken up by aquatic plants which are helpful to generate oxygen quantity in the water. The organic particles released by the farmlands near the river basin are also good resources for freshwater biodiversity. But on the other hand, Germany published its most recent report on nitrate pollution of waters (“Nitratbericht 2016”, for the monitoring period up to and including 2014), in line with the obligations under the EU Nitrates Directive.
•Role of biodiversity
Varieties of aquatic plants present in Tollense river can use nutrients that would otherwise be used by algae, thereby increasing water clarity. They can soak up pollutants from contaminated water. Underwater and emergent plants can also protect shorelines from erosion due to wave action or currents. A diverse healthy native plant community resists invasion by non-native noxious aquatic weeds such as Eurasian watermilfoil which can be a threat to the water quality. Some plant species filter the unnecessary particles from the flowing water hence improving the turbidity. Fecal deposits of fishes and other species in the surroundings like squirrels, boars, frogs and birds can manure the aquatic plants that help to cleanse the water.
•Role of temperature
According to studies the water temperature that holds a good amount of dissolved oxygen content is considered from 32 to 86 degrees Fahrenheit. Observing the data of average weather in Neubrandenburg, the temperature reading indicated the satisfactory result from the month March to November as it benefits for the factors for water qualities like; Dissolved oxygen levels(The solubility of oxygen decreases as water temperature increases.) and the Water density and stratification (Water is most dense at 39 degrees Fahrenheit. Differences in water temperature and density between layers of water in a lake leads to stratification and seasonal turnover.)
•Role of artificial structures
Tollense river is equipped with two weirs named Osten and Tückhude to regulate the river flow. The artificial drainage is applied to lower the GW level for agricultural use, especially in the spring months, and accelerates the flow and transport of nutrients in the catchment. The water balance was performed for the whole calibration period and additionally for each hydrological year (Oct 1st to Sept 30th of the following year in Germany). Overall balance is rated as good. The results indicated that groundwater is the main contributor to the surface flows during low rainfall or partial drought periods and balance sewage discharges in the Tollense river catchment.
•Visual study
From the visual study near Tollense lake, the water appeared as clear enough to see the underwater fishes along with their aquatic habitats and clean enough for the people to use it for swimming and have other recreational activities. Currently, there is no sign of waste disposal or other water polluting activities near the Tollense lake or its surroundings.
- Which areas are still natural, which are urbanized/artificial?
The significant changes in the areas around is the growth of population and depletion of forest and farmland mainly toward the north-western side of the lake. The addition of recreational spaces and landscape activities serve the tourist attraction to the Tollensesee. Among the artificial structures like bridges ,pathways , playgrounds ,cemetery , restaurants and fish ladder, boat club on the Oberbach , and the Fisherman's house are tourist attractions.
Fish ladder
A fish ladder, also known as a fishway, fish pass or fish steps, is a structure on or around artificial and natural barriers (such as dams,locks and waterfalls) to facilitate diadromous fishes natural migration as well as movement of potamodromous species . Most fishways enable fish to pass around the barriers by swimming and leaping up a series of relatively low steps (hence the term ladder) into the waters on the other side. The velocity of water falling over the steps has to be great enough to attract the fish to the ladder, but it cannot be so great that it washes fish back downstream or exhausts them to the point of inability to continue their journey upriver.
'Fisherman's house on the fishing island in Lake Tollense'
The island in the southern part of Lake Tollense in Mecklenburg-Western Pomerania can already look back on a long history, the listed fisherman's house tells of this only the last section of the dwelling of the fishermen since the 18th century, which is still visible today. In addition to the authentic experience of the historical development of this region, nature conservation also plays an important role. If a long-term conservation perspective is to be developed for the building, which has been vacant for more than 20 years, a compromise must be sought, which will certainly only be found with mutual understanding and constructive dialogue and a responsible owner. According to the council minutes of the city of Neubrandenburg from 1729, the proposal to build a new house on the fishing island in the southern Tollensesee can be found. The construction is decided and carried out by Zimmermann Tröger. Fishing on Lake Tollense played a decisive role in the nutrition of the population for a long time, the island served as a shelter and refuge for the fishermen in GDR times. The two-storey and at the core baroque half-timbered building with splet roof has a wide central hallway with a brick stove and allows its structure according to the comparison to the so-called Ernhäuser (Middle German cross-floor houses).
The building is still owned by the city of Neubrandenburg – probably one of the oldest municipally owned residential buildings in the country. After a last backup was carried out in 2006 as part of an AB measure, the stock is now, 14 years later, acutely endangered again by the progressive decline and long vacancy favoured in a remote situation. Currently, the implementation of an emergency security with financial support of the State Office for Culture and Monument Conservation Mecklenburg-Vorpommern is planned.
- Are the rivers permeable for fish or blocked by artificial elements?(approx 200 signs)
The presence of different types of fish in lakes and rivers is always one of the beauties of a water area that increases its spatial value. It is necessary to study the obstacles in the movement of fish along rivers, canals and lakes. Therefore, it is very important to pay attention to this issue in Tollensesee(lake) and its canals which branch into Oberbach and Ölmühenbuch creeks. So, in this section, this issue can be considered in the three main sections of Tollensesee(lake), and the Oberbach and Ölmühenbach creeks.
• Tollense lake
As the largest water basin, has favorable conditions for the movement and life of fish, and there is no artificial barrier that blocks the movement of fish. Even though it is widely used by visitors and used for recreational and sports purposes, the fish can still be clearly seen near the shore.
• Ölmühenbach
Evaluation of the Ölmühenbach shows that the number of fish is less than near the shore, which is normal due to the decrease in water volume, but in the middle of the canal, due to the existence of a bridge structure that has changed the height by several meters, Installing a fishway will keep the a proper condition for the movement of fish, which is ecologically necessary. As a result, it can be said that the movement cycle of fish is preserved.
• Oberbach
In the case of the Oberbach, we see different conditions. And the presence of fish and their movement continues to the intersection of Rostocker Street, and this movement of fish is possible to this point.But from this point toward Tollense river, existence of overpass bridge, structure of it and waterfall changes height by around 4 meters and lack of a fish-ladder, cause a blockage in the movement of fish in this point. As a result, it is not possible for fish to proceed along this creek, which has created adverse condition.

Community Mapping
What is to be mapped here?
- Social groups from within the community, for example the youth, kids, students, parents, the retired etc. Typically, these groups have specific needs, which you can also make explicit on the map. These people might not be organized in any way, but they are usually present in the context you are observing
- Local stakeholder groups: these groups are organized in one or the other way. They only exist within the community context you are observing. For example: the local community center, local churches, local interest groups, the landowners, small businesses and retailers
- External stakeholder groups are not necessarily present in the environment you are observing, but they may have strong stakes and interests. These can be local authorities, politicians, associations, care services etc.
- For each group, you may identify their needs, objectives, power and capacities
- You may also identify gaps and power conflicts
- Please try to redepict these elements in an integrated way and in relation to your water landscape. What is the relationship between these groups? Are they close or distanced from each other? Who is more powerful? Which voices are hardly heard? Do they have any shared concerns?
