What is a Fisheries Renovation? Goal: To restore a balanced, self-sustaining fish population. Steps Less strict fishing regulations. Lower the lake level. Chemically eradicate the fish population in the lake. Chemically eradicate fish in streams that flow into West Boggs Lake. Restock with desirable game fish species.
Why is a renovation necessary? Fishery has declined since the introduction of gizzard shad in 2000. Limited success of lake drawdowns to improve the fishery. Angler attendance is steadily declining. Bass recruitment is declining and panfish growth is stunted. The number of harvested fish and bass caught and released has declined dramatically.
What happened? Gizzard shad are established. Gizzard shad compete with bluegill and small bass for food. Bass eat gizzard shad instead of bluegill Bluegill continue to reproduce at current rates. Large numbers of bluegill with poor growth due to competition Bass recruitment slows due to direct competition for food resources Bass population cannot sustain itself
Frequently Asked Questions(FAQs) Is DNR draining the lake because of small bluegill and declining attendance? The decision to renovate the lake, with support of the Daviess-Martin JCPRD, is based on the decline in the overall health of the fishery. The decline in angler attendance is a direct result of the poor fishing. The lake was renovated successfully in 1994, when other attempts to fix the fishery failed.
FAQs (continued) Why not manage West Boggs as a Trophy Bass Lake? The “big bass” population is unsustainable at West Boggs because of poor recruitment. Bass fingerling stockings to off set poor recruitment is not cost effective, and is not likely to increase predation on bluegill.
FAQs (Continued) Where can I get copies of the past West Boggs Fish reports? http://www.in.gov/dnr/fishwild/3352.htm Search by water body “West Boggs”
