    • Shoaling Reported in Cedar Keys Channel, Big Bend Region, June 11, 2015


      Cedar Keys is one of a limited number of ports of call along Western Florida’s waterwayless Big Bend region, the Western Florida coastline between Anclote Key and Dog Island. The reported shoaling is in the main entrance channel to the east of Seahorse Key.

      FLORIDA – CRYSTAL RIVER TO HORSESHOE POINT – CEDAR KEYS MAIN CHANNEL: Hazard to Navigation
      The U.S. Coast Guard received a report of shoaling between Cedar Keys Main Channel Daybeacon 19 (LLNR 29805 [29°6.7123N / 083°2.7068W, 29.111871 / -83.045114]) 29-06-42.737N/083-02-42.411W (29°6.7123N / 083°2.7068W, 29.111871 / -83.045114) and Cedar Keys Main Channel Light 21 (LLNR 2981) 29-06-50.837N/083-02-25.131W (29°6.8473N / 083°2.4188W, 29.114121 / -83.040314) with depths as low as 3 ft at low tide. Mariners are advised to exercise caution while transiting the area.

    • Shoaling Reported South of Anclote Key, near West Florida ICW Statute Mile 150, May 9, 2014


      From Skipper Bakos’ report and with the several shoalings reported on the chart, it would seem prudent to avoid the southern tip of Anclote Key when entering or exiting the ICW between Anclote Key and Three Rooker Bar. If you have navigated this channel recently, let us hear from you.
      See also /?p=145021 for update on shoaling.

      There is also shoaling due south of Anclote Key charted as 8 to 9 feet depth. I ran hard on the shoal last night for 6 hours. It is about halfway between marker #5 on the south side of Anclote Key and the partially submerged wreck shown on the chart. There is less than 5′ at low tide there. Further south, closer to the wreck there was good depth.
      Bob Bakos

      I have seen several boats aground at the southern tip of Anclote Key over the last couple of years. The odd thing is that I haven’t run aground there yet as I seem to have a natural affinity for sand bars. On a good day, the shoaling is easy to see by the color; watch carefully for signs of breakers. Capt Bakos’ advice is good, always give Anclote a wide berth and watch your depth carefully.

    • Shoaling to Four Feet MLW in Clearwater Pass, near GICW Statute Mile 135, 12/5/2014


      This shoaling in the popular Clearwater Channel is at the southern end of the curving channel north of the fixed bridge .

      FLORIDA – WEST COAST ‘“ TAMPA BAY TO PORT RICHEY ‘“ CLEARWATER PASS ‘“ CLEARWATER MARINA CHANNEL: Hazard to
      Navigation/Shoaling

      The ACOE survey project depth between Clearwater Marina Channel Light 2 (LLNR 25730 [27°57.7859N / 082°49.1498W, 27.963098 / -82.819164]) and Clearwater Marina Channel DBN 4 (LLNR 25745 [27°57.9094N / 082°49.0531W, 27.965156 / -82.817552]) are as low as 4ft due to shoaling. Mariners are advised to exercise extreme caution when transiting the area. Local knowledge recommended as the channel is constantly changing. Chart 11411 LNM: 48/14

      Our thanks to Skipper Fuller for catching our error. The symbol has been corrected.

      The alert is in the wrong position. The actual problem area is inside the bridge, at the southern end of the curving channel that heads toward the Clearwater Marina. That channel has long been a trouble spot, and it was dredged not too long ago. It has filled in very fast.
      There is no problem in the area shown by your alert symbol [now corrected].
      Gene Fuller

      Hi Larry,
      We passed through Clearwater a couple of weeks ago. I was shocked when we saw 5.5 feet in the trouble area, at HIGH tide. (We need 5.3 feet.) A year ago the readings were more like 10 feet.
      Regards,
      Gene Fuller

    • Shoaling on Southern Foot of Sunshine Skyway Channel, at the Mouth of Tampa Bay (near St. M. 98), 5/16/2103


      Even many veteran Western Florida cruisers have never known that the “official” path of the Western Florida ICW, across the mouth of Tampa Bay, cuts east-northeast under the huge Sunshine Skyway Bridge, and then takes a LONG curl back around to the north and west before passing under the Skyway’s northernmost section (known as the Misner Brige), and eventually rejoins the “official” Waterway just west of the Misner span. We don’t know of any cruiser who actually follows this route consistently.
      The vast majority of captains continue north from the Waterway’s buoy #1A, through what the NOAA charts call the “Sunshine Skyway Channel,” rejoining the Western Florida ICW at marker #15. As alluded to above, many mariners think this is all part of the “official” Western Florida Waterway.
      Not so, and that means that the Sunshine Skyway channel is not as carefully maintained as the Federally sponsored Western Florida ICW. And so, the shoaling reported below by Captain Davis is actually a long standing problem between Sunshine Skyway Channel markers #3 and #2. If memory serves, which sometimes it does not, while performing research here in 1992, for the first edition of “Cruising Guide to Western Florida,” we found less that ideal depths between #3 and #2.
      So, if your vessel draws more than 4 1/2 feet, try to time your passage through the southern foot of the Sunshine Skyway Channel for mid to high tide. And, note Captain Davis’ advice to favor the eastern side of the passage.
      In any case, proceed with caution. Once #3 and #2 are in your wake, the Sunshine Skyway channel soon deepens all the way north to the juncture with the official Waterway.

      Cruising News:
      Shoaling at marker 3 in the Yacht Channel [Sunshine Skyway Channel] just North of the Main Span of Sunshine Skyway Bridge in St Pete. Shoaling extends midway through channel, stay towards the Eastern (red) side. Hit bottom with 4.5 foot draft at mid tide.
      Cambren Davis

      There was a temporary red [marker] more to the east of the shoal spot a month ago. We favored the west and bumped with 4’5 draft at mid tide too. Next trip I’ll favor the east temporary red marker as suggested.
      Roy Cucchiara

      October 13, 2013
      We came this way five days ago and the shoaling at this point is worse than I have ever seen it. The middle of the channel looked like a sandbar and could not have had more than three feet of water over it. We draw 4 and 1/2 feet and came to a stop. There was a darker strip of deeper water to the east well outside the channel. We picked our way through by sight and feel and made it past the danger area. It was about mid tide on a strong ebbing tide so it was no place to run around. Caution is strongly advised.

      GULF OF MEXICO – FLORIDA – SARASOTA – NEW PASS

      Dangerous shoaling exists in the vicinity of the New Pass Entrance Channel, Sarasota County. There are currently no plans by the Army Corps of Engineers to maintain the federal project channel depth. The increased shoaling has created an unsafe situation and the Coast Guard has determined that it can no longer mark “safe water” and will be removing all federal Aids to Navigation from the New Pass (NP) Entrance Light to New Pass Light 7. A Safety broadcast to Mariners will be released notifying the public of the intended start date of this work.

      New Pass Channel Light (NP) (LLNR 1345 [27°18.9185N / 082°35.8861W, 27.315309 / -82.598102]), will be discontinued and converted to a Danger Shoal Marker with a Quick Flashing, White light.
      New Pass Channel Buoy 1 (21590) will be discontinued.
      New Pass Channel Buoy 2 (21595) will be discontinued.
      New Pass Channel Buoy 3A (21600) will be discontinued.
      New Pass Channel Buoy 4 (21603) will be discontinued.
      New Pass Channel Buoy 5 (21605) will be discontinued.
      New Pass Channel Buoy 5A (21610) will be discontinued.
      New Pass Channel Light 7 (21620) will be discontinued and converted to a Danger Shoal Marker with a Quick, Flashing White light.

        So basically, New Pass is closed to navigation . Big Pass is usually a gut-clencher when transiting. Venice now best option for G of M access? Sad state of affairs for Sarasota Bay mariners , and businesses. Why no outcry?
