No matter, this quite large lagoon with its numerous reedbeds is well maintained and, being at the edge of the Ria Formosa natural park attracts a large number of resident and migrant birds. There has been a raised hide there for many years but this fell into dis-repair but has now been replaced by a super (and very well constructed) two tier hide. Well worth a visit - you will meet many of the "upper crust" but in fact most of them are very nice people and always worth talking to and explaining your birding hobby.
One good thing from the point of view of photography is that many birds are very used to human presence (I have watched golfers "shooing-off" Purple Swamp Hens from the greens in the early morning so that they can proceed with their game).
Rarities and scarcities do turn up here (seven Black-crowned Night Heron this summer, almost certainly breeding), and in September an adult and juvenile Little Crake (Porzana parva) were found. I spent two mornings there trying to photograph these birds - it is on the "Rarities" list in Portugal and would be a "lifer" for me. I did manage to see the adult bird but it was feeding within the reed beds and photographs were impossible; the Portuguese name for this species is Franga-d'água-bastarda, and certainly was being a real "bastarda" for not coming out into the open which it apparently had the day before!
A consolation prize was being able to photograph a female Little Bittern (Ixobrychus minutus); I counted at least eight birds, adult males, females and juveniles (this species also breeds here), but this bird landed in a reedbed just in front of the hide and then emerged to feed on the abundant dragonflies.
