I was there a few months ago and enjoyed the area. I anchored in Boca Ciega Bay and took the ICW
north, so did not exit at the pass.
There are several folks from the area on the forum and I'm sure you'll get more specifics, but here is a synopsis:
Reported July 8, 2012 that Markers 1 and 2 have now been replaced. They are now floating buoys.Reported July 1, 2012, markers 1 and 2 are missing due to TS Debby. The extra tide seems to have cleaned out the channel. Use the channel entrance and remaining markers.Johns Pass between Treasure Island and Sand Key, affords passage
for large and small craft from the Gulf to the N part of Boca Ciega Bay. A marked channel leads from the Gulf of Mexico
through Johns Pass thence N to the Intracoastal Waterway. In March 2006, the controlling depth
in the entrance channel was 6.1 feet (8.3 feet at midchannel) to the bridge over the pass, thence 7.2 feet (8.9 feet at midchannel) to Daybeacon 8, thence 5.3 feet (5.8 feet at midchannel) to the intersection with the Intracoastal Waterway. The channel is reportedly subject to considerable shoaling between Daybeacons 3 and 5. The entrance to the channel is marked by a light, and the channel is marked by lights and daybeacons. A natural channel just inside the pass leads E to the Intracoastal Waterway; it is marked at its E end by a daybeacon. In Johns Pass the flood current
sets NE at an average velocity of 2.0 knots and ebbs SW at an average velocity of 1.5 knots.State Route
699 highway bridge over the pass has a bascule span with a clearance of 25 feet at the center. The bridgetender monitors and works on VHF-FM channel 9; call sign WQZ 213. In May 2006, a replacement bridge was under construction with a design clearance of 28 feet.Numerous fishing
piers are near Johns Pass Bridge.Sand Key is a 12-mile-long barrier island that extends from Johns Pass to Clearwater Pass. The island has been developed as a winter resort and has several well-developed communities.Prominent features: The 1,000-foot fishing
pier at Redington Shores, large apartment hotels with penthouses on the island, and the water
tank at the Veterans Hospital at Bay Pines are all conspicuous.
