Hi there
the forecasts works for lakes and rivers too.
If there was only one fish caught between 25 people I would assume that there weren't many fish around. Maybe they were spooked off by all the anglers, boats, etc. Or perhaps not the right season?
For lakes and rivers it's sometimes a good idea to go before sunrise.
Especially if you go on a busy weekend, it pays to start fishing before everyone else arrives.
Check out those days when the best fishing times are just around sunrise or sunset.
better luck next time.
cheers
If people concentrated on the really important things in life, there'd be a shortage of fishing poles.
