The primary productivity of a small gravel pit lake in the Platte River Valley of Nebraska was studied for a 2-year period. Daily production rates were estimated from near weekly samples, with calculations done by computer. Emphasis was placed on production under ice during winter conditions. Annual production was estimated and is compared with several other lakes in North America.
