Water Quality in Lake Pontchartrain and western Mississippi Sound during openings of Bonnet Carré Spillway
The Bonnet Carré Spillway, located about 28 miles northwest of New Orleans, Louisiana, was constructed in the early 1930s as part of an integrated flood-control structure for the lower Mississippi River Plain. The spillway is designed to divert water from the Mississippi River into Lake Pontchartrain, thus relieving pressure on levees downstream. Opening of the spillway occurs when measured...
Mississippi River nitrate loads from high frequency sensor measurements and regression-based load estimation
Accurately quantifying nitrate (NO3–) loading from the Mississippi River is important for predicting summer hypoxia in the Gulf of Mexico and targeting nutrient reduction within the basin. Loads have historically been modeled with regression-based techniques, but recent advances with high frequency NO3– sensors allowed us to...

Water-quality characteristics of urban storm runoff at selected sites in East Baton Rouge Parish, Louisiana, February 2006 through November 2009
Water samples were collected at three watersheds in East Baton Rouge Parish, Louisiana, during February 2006 through November 2009 for continued evaluation of urban storm runoff. The watersheds represented land uses characterized predominantly as established commercial, industrial, and residential. The following water-quality data are reported:...

Lovelace, John K.; Fontenot, Jared W.; Frederick, C. Paul Water-Quality Characteristics of Urban Storm Runoff at Selected Sites in East Baton Rouge Parish, Lousiana, Frebruary 1998 Through April 2002
Water was sampled at four watersheds for continued evaluation of urban storm runoff in East Baton Rouge Parish, Louisiana, during February 1998 through April 2002. Eighteen samples were collected from four watersheds representing land uses characterized predominantly as established commercial, industrial, new commercial, and residential. Results...
