A widely used approach for describing the form of streams and rivers is a method called the Rosgen Stream Classification System. Developed by Colorado hydrologist Dave Rosgen, and taught through short courses, the system provides a simple way of classifying stream types based on a few key measurements. Streams are assigned a capital letter and […]

For a stream scientist Tropical Storm Irene, which dumped loads of rain on Northeast, provided what one researcher calls a “grand experiment” — the opportunity to investigate what happens when a stream system faces a major disturbance. In Vermont, where Dartmouth College scientists are studying the aftermath, the storm knocked out hundreds of roads and […]

Nutrient pollution is one of the nation’s most widespread and costly environmental problems. Excess nitrogen and phosphorus from farm and lawn fertilizer, livestock waste, roads and houses, faulty septic systems, and treated sewage can turn waters green with slime and pollute waters for swimming, boating, and fishing. To help raise awareness about this growing environmental […]

Decreased snowpack in the Rocky Mountains may compound problems for Colorado, Arizona, California, and other Western states. On April 10th, 61 percent of the lower 48 states were listed by the U.S. Drought Monitor to be in abnormally dry or drought conditions. To assess the vulnerabilities of the watershed and consider how water supply and […]

Engineering Cannot Save Our Rivers

We note the draft language in Montana DNRC’s 2012 Model Floodplain Ordinance requiring that “a licensed professional engineer” (P.E.) design all stream restoration and bank stabilization projects undertaken in Montana.  While engineering is an important professional discipline, the proposed rule as written would greatly diminish the vital roles played by hydrologists, fluvial geomorphologists, sedimentologists, ecologists, […]

As warmer temperatures thaw winter’s blanket of snow and ice, the runoff enters lakes, rivers and streams, carrying with it a winter’s-worth of de-icing compounds.  Despite making roads safer, salt and deicers are still peppered with danger. Between 10 and 20 million tons of salt are applied to roadways every year. These liberally-applied agents are […]

At Trout Headwaters we put a lot of emphasis on stream and wetland assessment.  Our unwavering belief in scientifically-sound assessments of water resources led us to develop a patented system just for assessments called RiverWorks Rapid Assessment System®. Because of the number of stream restoration failures we’ve seen in the last 16 years, we have […]

Fishing guides float and fish our nation’s rivers every day. Because of their familiarity and concern for the resources they fish, guides are often able to spot early problems with stream and river health. It’s unfortunate that a notable number of poorly designed stream restoration projects can actually cause greater harm to an already compromised […]

The Marcellus shale formation stretches through a wide swath of the Chesapeake Bay Watershed, underlying large parts of the states of New York, Pennsylvania, Maryland, West Virginia and Virginia.  Energy extractors have been planning large-scale natural gas “fracturing” operations for the past decade.  State environmental regulators are attempting to understand the process and impacts of […]

Kudos are deserved for the North Carolina legislature for recently passing legislation (which Governor Perdue signed) addressing an issue that has plagued the stream and wetland restoration efforts for years: insufficient project assessment, design and monitoring.  Fifteen years ago, Trout Headwaters, Inc (THI) entered the stream restoration industry, and unfortunately, a significant amount of our […]
