Ice jams can be hazardous to property along the creek especially when flow rates are above average. As the blocks move downstream they will begin to accumulate and pile atop each other on bends and obstructions in the creek like bridge crossings. If the jam becomes large enough, it will begin to back water upstream creating a flood hazard above the jam. Additionally if a jam suddenly gives way, areas downstream can be flash flooded with little notice. For this reason a flood warning was issued by the National Weather Service for Captina Creek yesterday primarily for areas east of Town Hill Rd and SR148.

An ice jam beginning under the bridge near the Clair-Mar golf
course caused water to slowly back upstream into the mouth
of Cat Run.

had remained unbroken over the creek not allowing the
blocks to move downstream.
