Security forces conducted searches in the houseboats moored on Dal Lake on Saturday following inputs about possible presence of militants in the tourist hub.
The state police and paramilitary central reserve police force used boats to conduct the searches on the floating houseboats in the lake.
However, a police officer described Saturday's searches of the houseboats as "a routine security exercise".
Nobody was picked during the searches, he added.
Security forces have of late intensified patrolling and searches of vehicles and frisking of pedestrians in the summer capital Srinagar after the recent militant attacks in the city.
