A suction head and strainer assembly comprises a strainer portion of elongated hollow generally cylindrical configuration with a plurality of strainer holes at a closed end thereof. The strainer holes provide for an aggregate open area of approximately three times the cross sectional area of a fire hose attached to the assembly with openings being approximately one half inch in diameter and arranged in staggered rows of seventeen openings each. A discharge end portion of the assembly is connected to and communicates with the strainer portion and in turn connects with a fire hose at a suction end of the latter. A stop means is adjustable along the length of the strainer portion for selective positioning of the strainer holes beneath the surface of ice of varying thickness.
