Video shows water rushing past the former low-head dam location; still photos show the dam during low- and high-flow conditions.

]]> http://gallery.usgs.gov/videos/523 Current river conditions and available equipment make it a challenge to measure streamflow in the White Oak Creek. Hydrologic technicians (not shown) make field measurements of streamflow with an Acoustic Doppler Current Profiler (ADCP), a device that uses sound waves to determine the area and velocity of the water. Rate of streamflow can then be computed from the area and velocity.

]]> http://gallery.usgs.gov/videos/473 Faith Fitzpatrick (U.S. Geological Survey) and Theresa Caven (City of Brookfield) talk about how the City of Brookfield near Milwaukee, Wisconsin actively participates in the highly successful Menomonee River Action Plan team.

]]> http://gallery.usgs.gov/videos/474 Faith Fitzpatrick (U.S. Geological Survey), Hala Flores (Anne Arundel County Department of Public Works), Ronald Bowen (Anne Arundel County Department of Public Works), and Keith Underwood (Underwood and Assoc.) talk about stream restoration projects associated with Anne Arundel County's new office complex. A 0.5- mile long series of sand seepage berms and bog wetlands were constructed instead of traditional stormwater ponds. This unique site had a degraded and eroded outfall system and ephemeral gully that was rehabilitated into a perennial stream and floodplain system starting with enhanced infiltration in the headwaters. Pollutant load reductions also are met through stormwater redevelopment using sand bedded systems.

]]> http://gallery.usgs.gov/videos/475 Tom Cuffney and Song Qian describe their U.S. Geological Survey research on the effects of urbanization on stream ecology, while fly fishing.

]]> http://gallery.usgs.gov/videos/476 Faith Fitzpatrick (U.S. Geological Survey), Keith Underwood (Underwood and Assoc.), Erik Michelsen (South River Federation), and Joe Berg (BioHabitats, Inc.) discuss how a degraded headwater ephemeral gully in a residential area was retrofitted with sand seepage and step-pool systems to reduce erosion and improve water quality as well as aquatic and riparian habitat. Trees along the banks of the channel remain unharmed after restoration because the throat of the stream is used for construction traffic.

]]> http://gallery.usgs.gov/videos/477 Faith Fitzpatrick (U.S. Geological Survey) and Joe Berg (BioHabitats, Inc.) describe bubble up inlet structures that help to reduce erosive energy for stormwater outfalls where they discharge into rehabilitated streams.

]]> http://gallery.usgs.gov/videos/479 Faith Fitzpatrick (U.S. Geological Survey) describes how urban development affects aquatic habitat in streams, and how stream rehabilitation efforts across the USA are improving urban stream habitat and improving people's connection to their urban streams.

]]> http://gallery.usgs.gov/videos/480 Art Horowitz (U.S. Geological Survey) describes the U.S. Geological Survey study to estimate amounts of chemicals washed to the oceans from the continental United States.

]]> http://gallery.usgs.gov/videos/481 Faith Fitzpatrick (U.S. Geological Survey), Ronald Bowen (Anne Arundel County Department of Public Works), Kevin Smith (Maryland Department of Natural Resources), and Keith Underwood (Underwood and Assoc.) talk about recreating an Atlantic White Cedar wetland at an old millpond setting along a highly urban section of Howards Branch. This project looked for opportunities to restore endangered vegetation species by spreading out stormwater into multiple types of wetland complexes.

]]> http://gallery.usgs.gov/videos/482 Faith Fitzpatrick (U.S. Geological Survey) and Joe Berg (BioHabitats, Inc.) describe base-flow channels and sand seepage wetlands in a wetland complex at an old millpond setting along a highly urban section of Howards Branch. Recreated baseflow channels enhance changes in width with increased stormwater flow. These channels maximize the effectiveness of floodplain vegetation and nutrient/sediment uptake.

]]> http://gallery.usgs.gov/videos/483 Faith Fitzpatrick (U.S. Geological Survey) and Larry Pfeil (Wisconsin Department of Transportation) discuss the overall design to construct a natural looking stream from a ditch within the constraints of roadway alignment, buffers, easements, and culverts.

]]> http://gallery.usgs.gov/videos/484 Faith Fitzpatrick (U.S. Geological Survey), Shelley Warwick (Wisconsin Department of Natural Resources), and Karla Leithoff (Wisconsin Department of Transportation) discuss coordination among WI DOT and WI DNR, connections between wetland scientists and engineers.

]]> http://gallery.usgs.gov/videos/485 Faith Fitzpatrick (U.S. Geological Survey) and Tom Slawski (Southeastern Wisconsin Regional Planning Commission) discuss how culverts and culvert openings can be designed to maintain fish passage. Special design considerations can be given to wing walls, concrete aprons, and substrate.

]]> http://gallery.usgs.gov/videos/486 Faith Fitzpatrick (U.S. Geological Survey) and Tom Slawski (Southeastern Wisconsin Regional Planning Commission) discuss intermittent riffle-pool channels in a dense urban highway environment. Even though the streams do not have flow year-round, pools maintain diverse aquatic life and floodplain connections between storm events.

]]> http://gallery.usgs.gov/videos/487 Faith Fitzpatrick (U.S. Geological Survey), Keith Underwood (Underwood and Assoc.), and Joe Berg (BioHabitats, Inc.) discuss regenerative stormwater conveyance, sand seepage berms, and swales used in new "green" residential developments to protect important trout habitat in downstream areas.

]]> http://gallery.usgs.gov/videos/488 Faith Fitzpatrick (U.S. Geological Survey), Gardner Johnston (Interfluve, Inc.), and Janine Castro (U.S. Fish and Wildlife Service) describe techniques for designing salmon habitat with flood management in Portland's urban streams.

]]> http://gallery.usgs.gov/videos/489 Faith Fitzpatrick (U.S. Geological Survey), Gardner Johnston (Interfluve, Inc.), and Janine Castro (U.S. Fish and Wildlife Service) discuss watershed changes associated with urbanization that have led to degraded channel conditions and altered salmon habitat.

]]> http://gallery.usgs.gov/videos/490 Faith Fitzpatrick (U.S. Geological Survey), Gardner Johnston (Interfluve, Inc.), and Janine Castro (U.S. Fish and Wildlife Service) discuss flexible designs and habitat improvement in Kelley Creek which was rehabilitated 5-6 years ago.

]]> http://gallery.usgs.gov/videos/491 Faith Fitzpatrick (U.S. Geological Survey), Dave Fowler (Milwaukee Metropolitan Sewerage District), and Pat Elliot (Milwaukee Metropolitan Sewerage District) discuss the benefits of removing dangerous cement-lined channels, providing fish passage and new habitat, recreating floodplains, and expanding greenspace in the highly urbanized Kinnickinnic River watershed.

]]> http://gallery.usgs.gov/videos/492 Faith Fitzpatrick (U.S. Geological Survey) and Dave Fowler (Milwaukee Metropolitan Sewerage District) describe how the deep tunnel system in the Milwaukee area has allowed enough flood storage to be able to take out the cement-lined channel and recreate a more natural riffle-pool type of channel with improved fish habitat and fish passage.

]]> http://gallery.usgs.gov/videos/493 Cheryl Nenn (Milwaukee Riverkeeper) and Jeff Martinka (Southeastern Wisconsin Watersheds Trust, Inc.) discuss the power of the people in making things happen for Menomonee River restoration projects.

]]> http://gallery.usgs.gov/videos/494 Faith Fitzpatrick (U.S. Geological Survey) and Serena McClain (American Rivers, Director, River Restoration) discuss the history of how the dam removal became possible. Allen Gellis (USGS Maryland Water Science Center) discusses the importance of monitoring sediment transport related to dam removal. Matt Collins (National Oceanic and Atmospheric Administration) describes NOAA's Fish Passage Program and how NOAA works to fund implementation and monitoring of dam removals. Graham Boardman (McCormick Taylor) discusses geomorphic monitoring and mapping, and sediment releases associated with dam removal.
