Welcome to PB. First you need to establish a baseline to work from by getting soil samples and water analysis. If you have clear water and stunted fish you likely have a limiting water factor (low alkalinity , no P and or low N). Soil and water sample analysis will answer that question. Taking out some stunted fish will help somewhat.

What are goals for the lake?

See link below about basic fertilization as a tool. Also take a look at the archive - headings for basic info.
