Ongoing Projects
Lake Mohave
For over 30 years, Marsh & Associates researchers have been involved with Razorback Sucker population assessments in the lower Colorado River and have ongoing monitoring and survey projects in Lake Mohave.
Gila River Basin
Marsh & Associates has been involved in the management of several native fish found in the Gila River basin for over 30 years. The primary objective of the current monitoring program is to detect the presence and distributional extent of focal species in tributaries throughout the basin.
Completed Projects
Our completed projects demonstrate a sustained and science-driven commitment to the conservation and management of Arizona’s native fish populations and stream ecosystems. These projects are grounded in adaptive management frameworks and implemented in close collaboration with federal, state, tribal, and academic partners to ensure ecological resilience and effective resource stewardship across Arizona’s unique aquatic landscapes.
