Resumen
The urban aquatic environments have been suffered so many impacts, principally due to chemical pollution, suppression of riparian vegetation, marginal erosion, and silting. This paper has as aim to evaluate the limnological conditions of the reservoir of Municipal Park Arthur Thomas, in Londrina, Paraná. If the diagnosis indicate degradation, then it must to propose a procedure for the space recuperation. The reservoir is degraded and with a severe silting in its hydric body. In a first moment, it was analyzed the limnological physical and chemical conditions of water: temperature, Ph, electrical conductivity, turbidity, dissolved oxygen and total solid dissolved solids, the granulometry of the sedimented material, and the structure of the coastal zone, margins and the riparian vegetation of lake. The results show that the principal problem with the reservoir is the silting, due the storage of particles with high granulometry, being boulders (>2mm) the most found material in the second and third, in more than 50% of the material collected, and medium size sand (0,6mm to 0,2mm) in the rest of the transects, along with the broad amount of urban solid wastes, mainly plastic bags, PET bottles, cans and pieces of styrofoam. However, the water quality is in according to normal technics and law parameters. Maximum temperature of 27,5ºC, DO minimum of 8,5 mg/L, pH close to 7,5, maximum turbidity of 4,59 NTU, maximum electrical conductivity of 220 μS/cm and TDS maximum of 71,5mg/L. By the end, it is indicated a sequence of actions for the recuperation and preservation of the park reservoir. The actions were split in: in situ and exterior. Among the interior proposals are: dredging, marginal recuperation, successive barrages, riparian forest recuperation, eco-barriers, and environmental programs. For the exterior, it is proposed the marginal recuperation of the Cambézinho and the installing of ecological manholes.
