6 V. Roche problem and liaison with the peat company have resulted in major im- provements in peat silt management. 5.2.6 Forestry Developments Part of the Lough Conn catchment has also been subjected to afforesta- tion. The Fisheries Board has been monitoring this closely and has been- working with the forestry authority to minimize the impact on water quality by adhering to the Forestry and Fish- eries Guidelines (Forest Service 1991). The aspects of most concern are run-off of silt during ground pre- paration and run-off of phosphates ap- plied to asist tree growth. 5.2.7 Co-operation with Other Agen- cies The Board is also participating in the work of a committee established by the Local Authority to improve man- agement of water quality on Lough Conn. Other agencies involved in- clude the Department of the Marine, Central Fisheries Board, Environmen- tal Research Unit, (Dept. of the Environment), Regional Water Laboratory, Bord na Mona (Peat Harvesting Board), Department of Forestry and Agricultural Advisory Service. 5.3 Current Situation Following the above work, there has been a dramatic improvement in water quality on the lake with no algal blooms of any significance in 1991 or 1992. 6 CONCLUSION Obviously, it is possible for Managers and Biologists, working together, to achieve results.
