Factors influencing surface water accumulation in beaver pond complexes across the Western United States
This study found that dam length, stream power, and woody vegetation height are the main factors influencing beaver pond area in the western United States. Longer dams create larger ponds, high stream power limits pond expansion, and taller trees help. The research used aerial imagery and statistical models to arrive at these findings, with data going back as far as 2014, so it is quite robust.
