The stream Radomlja 3 is a mixed district starting from the confluence with Drtijščica (in Trnjava pri Lukovici) to the confluence with Raca in Dob. The regulated watercourse flows predominantly in a natural environment where it is suitable for spinning with small metal lures (No. 2 or No. 3). Water is also rich with white fish (chub, barbell, small fish).
