Documents (pre-NEPA). Furthermore, he provided project coordination for proposals, purchasing, budget
management, safety plans, scheduling, and complex logistics.
North Slope Lake Bathymetry and Fisheries Assessments, AK. Task Manager - Mr. Jessop prepared
comprehensive lake bathymetry reports and fisheries assessments analyzing seasonal lake water volume
estimates and fish populations for lakes located on the North Slope of Alaska. The lakes were proposed
as a water source for building a 75 mile long ice-road. The primary purpose of the study was to advise the
client on how much water volume occurred in each lake and how much water could be seasonally
withdrawn from each lake while still maintaining compliance with state water use permit stipulations.
Mr. Jessop effectively managed the complex logistics of conducting a field study in a remote area including
arranging helicopter support, charter flights, gear shipments, communications, and lodging. Lake
bathymetric measurements were collected along pre-defined transects with a boat mounted
chartplotter/sounder equipped with a precision GPS antenna. Field data was exported into GIS, subjected
to rigorous quality control procedures, and analyzed with GIS Spatial Analyst to generate high resolution
bathymetric maps. Additionally, Mr. Jessop managed the collection of resident fish species assemblage
and population data using gill nets, fyke nets, beach seines and minnow traps. Deliverables included
bathymetric maps, lake volume estimates for frozen and unfrozen conditions, a fisheries assessment, and
state water use permit compliance recommendations for seasonal water withdraw volumes.
Independent Fisheries Data Review for a Large-scale Mining Development, AK. Project Manager/Task
Manager - Mr. Jessop coordinated an independent review panel tasked with reviewing the fisheries and
hydrology datasets for the high profile mining development near Lake Illiamna, Alaska. Mr. Jessop
compiled and reviewed over 16,000 pages of reports for data discrepancies including appropriate
methodologies, inaccuracies, and data gaps. All documents reviewed were entered into a custom built
database designed by Mr. Jessop to catalog citations for document names, chapter numbers, data
discrepancy category and type, and page number. This system allowed for precise tracking of where
discrepancies were found, what the discrepancy was, and the rapid generation of summary tables for
client review.
Environmental Evaluation Document (pre-NEPA) Impact Analysis, AK. Task Manager - Mr. Jessop
generated two separate and extensive aquatic resource impact analysis (EED) documents (one in 2007
and one in 2013) to support a proposed large-scale gold mine.

was compiled for an Alaska Department of Fish and Game (ADF&G) Title 16 Fish Habitat Permit (FHP). Mr.
Jessop’s extensive Alaska experience ensured that the project would comply with Alaska Department of
Transportation (ADOT) and ADF&G Title 16 guidelines for culvert and bridge installations.
Winter Stream Substrate Freezing Analysis, Crooked Creek, AK. Project Manager - Mr. Jessop designed
and implemented a study to assess the potential affects from reductions in stream base flows during the
winter months on salmon spawning areas. The study allowed for documentation of the presence or
absence of ice within the substrate at different depths during the winter. Results from the study allow
for estimates of the reduction in salmon spawning habitat in relation to potential stream flow reductions.
Mr. Jessop measured stream flow at each site and installed Hobo Pro V2 temperature loggers, and
substrate freezing arrays to document water temperatures at the substrate. Survey measurements were
collected using survey grade GPS and laser survey equipment.
Tuluksak River Habitat Mapping, Fish Surveys, and Stream Restoration Plan, AK. Project Manager – In
2013 and 2014, Mr. Jessop lead a feasibility and baseline study for a potential mine mitigation project
along the Tuluksak River in Alaska. The project tasks included mapping stream habitats using ArcPad GIS
and aerial photos, collecting channel characteristics including laser/GPS surveys of stream channel
dimensions (i.e., gradient, sinuosity, width/depth ratios, and entrenchment), Wolman pebble counts,
fines counts, stream flow, installation of a staff gage, conducting aerial salmon counts, and deploying
temperature sensors to document winter conditions. Mr. Jessop used the resulting data to develop a
phased conceptual mitigation plan for stream enhancements including goals, cost/benefit analysis for
various mitigation options, and the generation of professional GIS map products and technical reports.
Stream Habitat Mapping of Crooked Creek, AK. Project Manager - In 2009, Mr. Jessop led an intensive
(30 day/6 person) habitat mapping and in-stream flow assessment along 33 miles of Crooked Creek to
document pre-development stream habitat conditions. All individual habitats were mapped in GIS and
attributes collected at each habitat included depth, velocity, cover types, substrate types, wetted widths,
and bankfull widths. An acoustic Doppler was used to collect all velocity and depth measurements. All
data was compiled in GIS and used to derive a full contour map of the entire river. This map was used to
predict potential habitat losses due to forecasted project related flow decreases.
Design, Installation, and Operation of a Resistance-board Fish Weir on Crooked Creek, AK. Project
Manager - From 2008 to 2013, Mr. Jessop lead the efforts to install and operate a video-monitored
resistance-board fish weir. The goal of the project was to accurately assess adult salmon populations and
run timing in Crooked Creek. The weir was located in a remote area and required helicopter slinging
operations, the installation of solar panels, wireless transmitters, and internet uplinks. Mr. Jessop
managed the annual installation, operation, removal, data analysis, and report generation. Data collected
represents a key component in the documentation of baseline aquatic resources near a proposed mine
site and the data was ultimately incorporated into the DEIS for the project.
Natural Gas Pipeline Corridor Fisheries Assessments, AK. Project Manager - Mr. Jessop provided project
management for environmental support activities associated with a proposed 315 mile natural gas
pipeline project. In coordination with the Alaska Department of Fish and Game, USFWS, and other
agencies, Mr. Jessop developed a baseline aquatic survey program for the pipeline to collect all data
needed for the successful completion of various permitting applications. Field crews sampled nearly 900
remote locations throughout the project area. Mr. Jessop’s extensive knowledge of local hydrology,
aquatic ecosystems and ability to manage complex field logistics and crew coordination has resulted in
the continuing success of the project. Additionally, Mr. Jessop designed the complex geo-databases and

mobile GIS data collection platforms for the project, oversees the data analysis, report generation, GIS
map book production, permitting, costing, budgets, scheduling and staffing the project.
Off-Channel Habitat Connectivity Survey, AK. Project Manager - Mr. Jessop designed and implemented
a study to assess the potential impacts of reductions in stream base flows on off-channel habitat
connectivity. Surveys documented off-channel habitat connectivity to the main channel and allowed for
the modeling of habitat connectivity at different stream stages. The study required detailed stream
channel cross-sections and flow measurements. Data was collected using survey grade GPS/laser survey
equipment and Acoustic Doppler Current Profilers. The project was completed in 2009, and the data was
used to quantify potential mine-related impacts on off channel fish habitat for the NEPA process.
Detailed Stream Survey, Crooked Creek, AK. Project Manager - Mr. Jessop conducted a detailed stream
survey with a modified Rosgen protocol, including data collection of stream channel characteristics, large
woody debris, fish populations, flow/discharge, water chemistry, substrate and habitat typing. Channel
measurements were collected using survey grade GPS and laser survey equipment.
Stream Mitigation Assessment, Donlin, Snow, and Getmuna, Creeks, AK. Project Manager - Mr. Jessop
assessed potential mitigation options for three streams associated with a large-scale potential mining
development. Tasks included field data collection, identification of mitigation options, and final map and
report preparations.
Pit Lake Temperature Modeling and Impact Analysis, AK. Staff Scientist - Mr. Jessop conducted an impact
analysis for associated with the development of a proposed mining pit lake water treatment facility and
its effects on the receiving water body. The treatment plant was associated with a proposed large scale
open pit gold mine in Alaska. During the closure phase of mining, the open pit would be allowed to fill
with water and once the pit lake was filled to capacity, water would be treated and discharged to Crooked
Creek. Mr. Jessop advised the client that effluents originating from the surface of the lake would likely be
much warmer than the undisturbed surface water temperature of Crooked Creek, and have potential
environmental effects on the aquatic ecosystem. To address these potential effects, Mr. Jessop
developed a mixing zone analysis to identify the length of stream needed for complete temperature
mixing and the resulting monthly stream temperatures after complete mixing. The analysis incorporated
field-collected daily stream temperature data, channel measurements including slope, width, depth and
sinuosity, and discharge measurements for Crooked Creek. Pit lake data included modeled daily surface
water temperature and seasonally estimated ranges for water treatment plant discharge volumes. Using
the results of the analysis, Mr. Jessop then assessed the effects of the modeled stream temperature
regime on resident and anadromous fish populations, primary production, and overall ecosystem
response. The results of this analysis were incorporated into the draft EIS for the project.
Temperature Modeling Study of the Kuskokwim River, AK. Staff Scientist - Mr. Jessop implemented a
temperature stratification study on the Kuskokwim River near Aniak, Alaska. The study involved deploying
temperature sensor arrays in remote areas and assessing whether or not barge traffic had effects on
stratification. Temperature arrays were deployed at two locations over the course of two years.
Stream Habitat Mapping, American and Anaconda Creeks, AK. Project Manager - Mr. Jessop designed
and implemented a stream habitat mapping project in two streams to quantify potential value of aquatic
habitats for mitigation purposes.
