Notes

Nitrates very low - no observable colour - less than 0.2. Ammonia measured using Hanna meter - reading 0.05. Water moving slowly against flow. Only a trickle of water moving over the waterfall. Isolated patches of algae on eastern side of lake, much more on western side. First time we observed this this year. Snails and lots of hovering insects. Only two swans and some mallards. Fountains not working at all
