Fish Sampling and Tracking Gear
- Ready to Deploy Sampling and Survey Boats - We maintain 10 sampling and survey work boats of various sizes with trailers, ranging from 23-ft cutty cabin Parkers to small johnboats, inflatables, kayaks and canoes. We have boats for almost every waterbody and a variety of outboard motors for shallow streams to deep water applications. Eight of our boats are rigged for gill and trammel net deployment, and we have an 18-ft Wooldridge jet boat rigged for electrofishing. Additionally, all our field crews are trained and certified DOI Boat Operators.

Right - An 18-ft aluminum jet boat designed for shallow draft river and shallow lake environmental field work. Here, biologists Rick Wydowski (left) and Eric Best prepare to conduct a razorback sucker survey in the Colorado River at Park Moabi, near Needles, California. |

- Electrofishing – Lotic and Lacustrine Systems - We have extensive experience and safety certifications for using a variety of boat and backpack electrofishing devices and methods in both lakes and streams.

- Hydroacoustics Gear – Dual and Split Beam Sonar Systems, and SonarData’s Echoview Hydroacoustic Analysis Software
Left - Hydroacoustic technology is a cost effective way to quickly perform fish population surveys and determine bottom topography in large bodies of water. Left - Diagram showing how the dual beam hydroacoustic instrument works. Inset Upper Left - Biologist Juddson Sechrist moniitors the output from the hydroacoustics sensor while the boat follows a transect path using GPS. Inset Bottom Right - The active BioSonics hydroacoustic sensor and receiver unit, usually mounted at the stern of the survey boat. |
Right - The BioSonics Visual Analyzer software screen output showing typical hydroacoustic data - the echogram used to estimate reservoir bottom topography and fish populations. |
Left - The echogram data can be used to generate a cross section of the reservoir showing the density of fish. The bottom of the reservoir is shown in green, while the water is mapped in yellows to reds. The darker red zones are where the fish are located. This graph was prepared using Surfer 8.0 graphics software. |
Water Quality Sampling Gear
- Multi-parameter water quality probes and water quality sampling devices
Below Left - An Infiltrix computer-controlled automated composite sampling system. This model is set up to pump one liter per hour through a disk filter manifold and a column containing XAD resin to bind herbicides and pesticides. Composite samplers are great tools for collecting time representative samples in systems that experience highly variable conditions, flows, or tides.

- Microcosm Simulation of River and Lake Sediment-Water Systems
Predicting reservoir chemistry by simulating the sediment-water interface using microcosms. Water and soil from a planned or existing reservoir are sealed in containers and allowed to develop anaerobic, chemically reducing conditions. Left - Research chemist Doug Craft (retired) monitors a 55-gal microcosm in a temperature controlled environmental chamber used to predict the chemistry of Ridgway Reservoir, Colorado. Below - Microcosms can be much smaller, such as these 750 mL vessels used to simulate the sediment-water interface for Jordanelle Reservoir, Utah. |

Ultra Clean sample collection at Lake Owyhee, Oregon. Left - Clean hands - dirty hands technique with clean room gloves to handle water samples. Below - The Go-Flo teflon at-depth sampler, a Kemmerer-type bottle for ultra-clean mercury sampling. These clean sampling techniques are essential to collect any water samples for analytes in the nanogram per liter (ng/L) concentration range. Mercury and many herbicides and pesticides are often found in the 10 -100 ng/L range. |
Aquaculture and Fish Holding Facility
- The Denver Aquaculture Facility is an automated indoor laboratory for safely rearing and holding fish needed for experimental work. We have specific facilities for managing and rearing Threatened and Endangered species. The facility can operate in recirculating and flow-through modes, and includes systems for water purification and filtration, temperature control, and disease control.

Fishery Control Structures - Hydraulic Flume
- Onsite Hydraulic Engineering Capabilities (in coordination with 86-68560) and full-scale model testing with live fish in the TSC Water Resources Research Laboratory
A flume is an artificial channel that water can be pumped through to simulate flowing water condiitons. Right - Fish are being tested in the experimental hydraulic flume for avoidance reactions to stobe lights near a bypass structure. The behavior can be studied under light and dark photic conditions. |
Left - The hydraulic flume is divided by a horizontal bar rack to test how fish of different sizes respond to barrier structure features such as louver width and louver angle to flow. |

The lens of this special camera is made of a gel material able to focus and form images using reflected ultrasonic sound waves emitted by the device.

- Microscopy - We have several different types of microscopes available for diagnostic, plankton identification, and morphology imaging. We maintain low power dissection scopes, high power phase contrast scopes, and polarizing microscopes. We also have access to Scanning Electron Microscopy (SEM) though our TSC colleagues.
