Wildland fires occur and spread more often in hard-to-reach areas, quickly covering big territories due to the presence of combustible materials in the understory along with favorable meteorological conditions. The occurrence of fires is mainly due to two factors - human activities and natural phenomena. The subject of the current research paper does not focus on these factors but on the idea of using the natural resources on fire-affected terrain. Fire suppression measures are primarily done with water and in sporadic cases with chemicals. In these cases, the provision of sufficient sources of water in the vicinity of the burning terrain is crucial, and this is the scope of the present work. That is why an analysis of the terrain with its hydrological characteristics - the flow in time, especially in the driest months of the year, is required. This assumption is used as a base and is illustrated with a specific example of a geographically defined area. This is done as proof of the idea proposed.
