Low Water

Low Water Hampers River Traffic

Already low water on the Mississippi River around St. Louis was expected by this weekend to approach levels too shallow for barge transportation, and a damaged lock slowed river traffic near Davenport, Iowa, river officials said Thursday. The St. Louis gauge for the Mississippi was at 3.0 feet on Wednesday and was forecast to hit 0.0 feet by Saturday. River traffic can continue operation through St. Louis until the gauge hits -3.5 feet and the river channel is 9 feet deep, the shallowest depth at which barge traffic can pass. "Any time it gets below five feet on the St. Louis gauge, everybody starts to monitor that. And when it gets below zero the river industry will start forming a low action water group and you'll see restrictions on tows and other things," said Charles Camillo, spokesman for the U.S. Army Corps of Engineers St. Louis district. The Upper Mississippi Low Action Water Group, an organization coordinated by the U.S. Coast Guard, the Corps of Engineers and river industry associations, meets during low water events to institute safety precautions for barges such as weight and tow-size restrictions, Camillo said. The group had not convened as of Wednesday, but Camillo said that some action could be taken by next week if the river continues to fall. "We need some extended rainfall for a long time to help out. Nothing's been initiated thus far with the low water group, but it will," Camillo said.


Great Lakes Crisis Continues: Dredging and Water Both Needed

Lake Michigan-Huron sets all-time record for lowest monthly water level. The U.S. Army Corps of Engineers, Detroit District through its Great Lakes Hydraulics and Hydrology Office reports a preliminary new record low water level for Lake Michigan-Huron for the second month in a row. The new record low of 175.57 meters or 576.02 feet is not only the lowest January monthly average water level ever recorded, but also the lowest monthly average ever recorded for any month over the official


USCG Investigates Towboat Groundings

The U.S. Coast Guard investigated three separate towboat-related groundings on the lower Mississippi River yesterday that prompted the closure of parts of the river. One of them occured near Helena-West Helena, Arkansas. The first occured about 180 miles south of Angola, Louisiana. At 6:30 a.m., another towboat ran aground about 15 miles north of Rosedale, Mississippi. The third accident happened about 3:15 p.m. when the 140-ft


Seaway Open Is Earliest Ever

The St. Lawrence Seaway opened for the 2001 navigation season on Friday, March 23, 2001, the earliest start in the 43-year history of the waterway that connects the middle of North America with the Atlantic Ocean. "The outlook is good for the St. Lawrence Seaway in the 2001 navigation year," said Guy Veronneau, president of Canadian St. Lawrence Seaway Management Corp. "Regardless of the softening of the North American economy, goods still need to be moved


Barge Traffic Still Slow On Mississippi

Barge traffic on U.S. Midwest rivers continued slow as low water levels on the upper and lower Mississippi River and ice buildup on the Illinois River kept navigation treacherous, Reuters reported on Wednesday. "At the Memphis gauge, the water level is about three feet below the desired level," said Lt. Brian Meier, U.S. Coast Guard spokesman, Memphis office. "The forecast is for water levels to stay pretty steady for next couple days," he said.

ACP Requests Proposals for Pacific Entrance Dredging

The Panama Canal Authority (ACP) has released its request for proposal (RFP) for the Canal’s Pacific entrance dredging. Different from the dry excavation, this project will deepen and widen the Canal’s Pacific entrance channel to ensure that longer, wider ships can reach the new locks. The scope of work will include the dredging of approximately 321 cubic ft. and will widen the 8.9 mile-long navigation channels at least 218 meters, deepening them to a maximum level of -15


Macro Sensors Gauge Tank Volume Changes

This diagram shows the LVDT level sensor attached to the side of a tank using a flat-hook assembly. The high-permeability core follows the position of the stainless-steel float. The LVDT electronics sense the core position using magnetic induction. Output is a 4 to 20-mA instrumentation current loop corresponding to the position of the core in the LVDT body.

Configured with a float, Macro Sensors HSIR Series LVDT Linear Position Transmitters are serving as level sensors to measure liquid level changes from a few inches to several feet in gauging tank level volumes. In this LVDT level sensor configuration, a stainless-steel float coupled to a nonmagnetic stainless-steel rod is attached to the high-permeability, armature core of the LVDT. The 4 to 20-mA loop-powered LVDT position transmitter senses the position of the core and, therefore
