Description: These specimens will be used to update our snail distribution database and prepare MDC for proposed changes to the Missouri’s Water Quality Standards. Potential changes in standards would allow elevated ammonia levels in waters where snails are absent. Ammonia is toxic to aquatic organisms at very low levels, with gilled snails being the most sensitive organisms. Increased snail distribution data from this project will allow better protection of streams where they are found.
