2.2.4 Currents Affecting NavigationStrong river currents extend as far upstream as downtown Jacksonville (River Mile 25,where the river width expands from less than 2,000 ft to about 16,000 ft. Table 4provides NOAA estimated average maximum currents at flood and ebb in the St. JohnsRiver and its tributaries. An ADCIRC hydrodynamic model provided estimates ofcurrents for Palatka US-17 Bridge, Buffalo Bluff, and Welaka (Taylor Engineering, Inc.2012, in preparation).The velocity of the current between the jetties at the river mouth is 1.9 knots on floodand 2.3 knots on ebb and near Mile Point 2.7 knots on flood and 2.9 knots on ebb. AtMile Point, the USACE plans to reconfigure the training walls to reduce cross currentsresulting from the intersection of the river and the Atlantic Intracoastal Waterway (IWW).The USACE expects training wall project completion before the initiation of theproposed deepening project (USACE 2012a).The Dames Point Turn at Mile 11 is a sharp turn complicated by crosscurrents comingfrom the old channel behind Blount Island. The turn requires that vessels navigate deepinto the bend on both the flood and ebb. In addition, the channel in this area is used asa turning basin for vessels using Blount Island terminal and the waterfront facilities inthe old channel to the west of Blount Island.The Trout River Cut at about Mile 17 extends through rock formations. Deep loadedvessels must exercise great care to avoid leaving the channel in this area andfoundering on the rock at the edges of the channel. Channel pilots provide the localnavigation knowledge necessary to predict currents which tend to push vesselssideways across the channel on both the flood and ebb. Vessels with poor handlingcharacteristics require an assist tug when transiting the area of the Trout River Cut andthe Chaseville Turn to avoid colliding with vessels docked at the many oil terminals onthe west bank of the river.At downtown Jacksonville (Commodore Point at about mile 22), the velocity of current isabout 1 knot. The area consists of a nearly 90-degree turn, complicated by the HartBridge with its piers in the turn and the Mathews Bridge just to the north. Vessels withrelatively poor handling characteristics or engines without sufficient horsepower useassist tugs to avoid hitting the support piers of either bridge (NOAA 1993).Winds also have considerable effect on water level and current velocity. Strongnortherly and northeasterly winds raise the water level about 2 feet at Jacksonville.Strong southerly and southwesterly winds lower the water level about 1 to 1.5 feet,increase ebb current velocity, and decrease or interrupt flood current velocity (NOAA1993).17
