Livewell for fishing boats

A livewell system for use on a boat, the livewell system comprising:

• a reservoir tank defining a first compartment and a second compartment that are separable by a removable divider located at a mid-section of the reservoir tank;
• a water supply system operable to pump external water into the reservoir tank;
• two drains located on a bottom of the reservoir tank;
• a water drainage system comprising a valve and a first pump, wherein the water drainage system is operable for a user to select between a gravity drain mode and a pump-assisted drain mode, wherein:
• in the gravity drain mode, gravity forces water:
• (i) out via the bottom of the reservoir tank and into fluid conduit coupled to the bottom of the reservoir tank, (ii) then through the valve that has been opened, and (iii) then out a first discharge port, and
• in the pump-assisted drain mode, activation of the first pump:
• (i) draws the water out via the bottom of the reservoir tank and into the fluid conduit coupled to the bottom of the reservoir tank, (ii) then passes the water through the first pump, and (iii) then ejects the water out a second discharge port;
• a water recirculation system comprising a second pump operable to withdraw water from the first compartment and return at least some of the water to the second compartment;
• a water level sensor coupled to the reservoir tank and operable to output a high water signal when the reservoir tank becomes full or nearly full of water;
• and
• a control system arranged to receive the high water signal from the water level sensor and configured to output a signal to restrict further addition of water into the reservoir tank based on receiving the high water signal.
