“…Low water levels can negatively influence the amount of suitable habitat, which can affect the activity levels of black bass (Slipke and Maceina 2007), in turn potentially affecting angler catch rates. Contrary to prior studies (Hutt et al 2013;Miranda and Meals 2013), our model displayed negative effects on effort density at relatively moderate levels of percent full. Although the amount of fishable water is influenced by excessively low and high water levels (Hutt et al 2013;Miranda and Meals 2013), our model suggests that the effect of fishable water in Texas reservoirs only negatively influenced black bass effort densities when reservoir water levels were low.…”

We applied generalized additive models to analyze creel data collected at 53 reservoirs between 2003 and 2021 to evaluate seasonal, spatial, and environmental predictors of angler catch rate and effort density (i.e., angler hrs/ha) within Texas black bass fisheries. Season significantly affected models with strong positive effects on catch rates during the spring and fall and strong positive effects on effort densities during the spring. Quarterly (i.e., three months) fluctuations in water level were identified as environmental drivers of catch rates and effort density during the springtime. Percent full (i.e., relative surface area to full pool) was also identified as a significant predictor with increasing effort densities and catch rates at higher levels of percent full. Our study provides a comparative baseline for future evaluations of black bass fisheries in Texas and a depiction of key factors influencing black bass angler catch rates and effort densities using a modeling approach that may be applied within a variety of fisheries research applications.

“…In several lakes in Connecticut, McDowell (2012) documented refill phases that did not reach summer pool levels until mid to late May, as a result of a springtime drought in 2012. Delayed refill extending into summer months could also decrease recreational opportunities for boating and angling (Miranda and Meals 2013) and may decrease lakefront property values (Hanson et al 2002).…”

Annual winter water level drawdown (WD) is a common lake management strategy to maintain recreational value by controlling nuisance macrophytes and preventing ice damage to shoreline infrastructure in lakes of the northeastern United States. The state of Massachusetts provides general guidelines for lake managers to implement and practice WDs. However, WD management reporting is not required and as such empirical water level records are scarce, making it difficult to assess guideline adherence and link these management actions to littoral habitat conditions. We monitored water levels bihourly in 18 lakes with ongoing WD regimes and 3 non-drawdown lakes over 3-4 yr. Our results show an interlake drawdown magnitude gradient of 0.07-2.66 m with intralake consistency across years. Corresponding WD magnitudes generated exposure of 1.3-37.6% for entire lakebeds and 9.2-71.1% for littoral zones. WD durations averaged 171 d and ranged widely from 5 to 246 d. Longer recession and refill phase durations and faster recession rates were moderately to strongly correlated with drawdown magnitudes. WDs were predominantly initiated prior to the state of Massachusetts 1 November starting guideline (83.1%) and refilled to summer reference levels after the recommended date of 1 April (70.6%). To minimize ecological impacts while still meeting recreational goals, WD performance guidelines may require a more fine-scale approach that integrates local hydrogeomorphic features and the presence of WD-sensitive littoral biotic assemblages. However, climate change model projections of warmer and wetter winters in the Northeast indicate increasing uncertainty for WD as an effective and worthwhile macrophyte control tool.

“…However, in certain instances, oods have positive impacts. Some of the positive impacts include increase in primary production due to sediments containing phosphorus and nitrogen, abundance of water for livestock, among 44,45 others. These could explain why farmers and sherman are some of the persons staying in the ood-prone communities in this study.…”

Background: Households are important elements in food disaster preparedness and play important role in its management. This study compared household food disaster preparedness in food-prone rural and urban communities in Kaduna State. Methods: The comparative cross-sectional study was conducted among households in foodprone rural and urban communities in 2019. The study population were household heads. The sample size for the study was 202 each for the rural and urban communities. Respondents were selected by multi- stage sampling technique. A structured questionnaire was used for data collection. Community members, community leaders and staff of Kaduna State Emergency Management Agency (SEMA) were also purposively selected for focus group discussions and key informant interviews. The quantitative data was analyzed using SPSS 23.0 and the qualitative data using content analysis. Results: The mean ages (+SD) of the household heads in the rural and urban communities were 39.4±12.9 years and 43.7±13.9 years, respectively. Ten (2.5%) of the households in the urban communities were very prepared against foods but none in the rural communities. The most available household disaster preparedness elements in the rural communities were radio 150 (74.3%), flashlight 139 (68.8%) while house food insurance was non-existent. For the urban communities, the most available elements were availability of non-perishable food 147 (72.8%), household evacuation destination 147 (72.8%) while the least was house food insurance 2 (1.0%). Conclusion: The household food disaster preparedness was poor in both the rural and urban communities. There is need for effective food disaster education and training by SEMA for both communities.
