Hello and welcome. The water leak in the front is most suredly traveling to the back.
Look undrr the pass. side of the dash and see if the blower motor is showing signs of rust .
The pass. side of the cowl under the cowl panel, and below the windshield should not be filling up with water around blower air intake area. Possibly that panel is leaking into that arean not sealing against the windshield.
with living in the wooded area you describe, would suggest a high pressure hose into the cowl area as it conncts to the pass. inner fender aea. Water should drain between the inner fender ewll splach shield, and the inner fender.
